Although Chihuahua is primarily identified with the Chihuahuan Desert for namesake, it has more forests than any other state in Mexico, with the exception of Durango. Due to its variant climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, an extension of the Rocky Mountains, dominates the state's terrain and is home to the state's greatest attraction, Las Barrancas del Cobre, or Copper Canyon, a canyon system larger and deeper than the Grand Canyon. On the slope of the Sierra Madre Occidental mountains (around the regions of Casas Grandes, Cuauhtémoc and Parral), there are vast prairies of short yellow grass, the source of the bulk of the state's agricultural production. Most of the inhabitants live along the Rio Grande Valley and the Conchos River Valley.

Public opinion pressured the U.S. government to bring Villa to justice for the raid on Columbus, New Mexico; U.S. President Wilson sent Gen. John J. Pershing and some 5,000 troops into Mexico in an unsuccessful attempt to capture Villa. It was known as the Punitive Expedition. After nearly a year of pursuing Villa, American forces returned to the United States. The American intervention had been limited to the western sierras of Chihuahua. Villa had the advantage of intimately knowing the inhospitable terrain of the Sonoran Desert and the almost impassable Sierra Madre mountains and always managed to stay one step ahead of his pursuers. In 1923 Villa was assassinated by a group of seven gunmen who ambushed him while he was sitting in the back seat of his car in Parral.

La Cueva De Las Ventanas (The Cave of Windows), a series of cliff dwellings along an important trade route, and Las Jarillas Cave scrambled along the canyons of the Sierra Madre in Northwestern Chihuahua date between AD 1205 and 1260 and belong to the Paquimé culture. Cuarenta Casas is thought to have been a branch settlement from Paquime to protect the trade route from attack. Archaeologists believe the civilization began to decline during the 13th century and by the 15th century the inhabitants of Paquime sought refuge in the Sierra Madre Occidental while others are thought to have emigrated north and joined the Ancestral Pueblo peoples.

and Camargo. In 1631 Juan Rangel de Biezma discovered a rich vein of silver, and subsequently established San Jose del Parral near the site. Parral remained an important economic and cultural center for the next 300 years. On December 8, 1659 Fray García de San Francisco founded the mission of Nuestra Señora de Guadalupe de Mansos del Paso del Río del Norte and founded the town El Paso Del Norte (present day Ciudad Juárez) in 1667. The Spanish society that developed in the region replaced the sparse population of indigenous peoples. The absence of servants and workers forged the spirit of northern people as self-dependent, creative people that defended their European heritage. In 1680 settlers from Santa Fe, New Mexico sought refuge in El Paso Del Norte for twelve years after fleeing the attacks from Pueblo tribes, but returned to Santa Fe in 1692 after Diego de Vargas recaptured the city and vicinity. In 1709, Antonio de Deza y Ulloa founded the state capital Chihuahua City; shortly after, the city became the headquarters for the regional mining offices of the Spanish crown known as Real de Minas de San Francisco de Cuéllar in honor of the Viceroy of New Spain, Francisco Fernández de la Cueva Enríquez, Duke of Alburquerque and the Marquee of Cuéllar..

In the constituent legislature or convention, the conservative and liberal elements formed using the nicknames of Chirrines and Cuchas. The military entered as a third party. The elections for the first regular legislature were disputed, and it was not until May 1, 1826, that the body was installed. The liberals gained control and the opposition responded by fomenting a conspiracy.

In 1562 Francisco de Ibarra headed a personal expedition in search of the mythical cities of Cibola and Quivira; he traveled through the present-day state of Chihuahua. Francisco de Ibarra is thought to have been the first European to see the ruins of Paquime. In 1564 Rodrigo de Río de Loza, a lieutenant under Francisco de Ibarra, stayed behind after the expedition and found gold at the foot of the mountains of the Sierra Madre Occidental; he founded the first Spanish city in the region, Santa Barbara in 1567 by bringing 400 European families to the settlement. A few years later in 1569 Franciscan missionaries led by Fray Agustín Rodríguez from the coast of Sinaloa and the state of Durango founded the first mission in the state in Valle de San Bartolomé (present-day Valle de Allende).

The general features of the preceding occurrence applied also to Chihuahua, although in a modified form. The first person elected under the new constitution of 1825 was Simón Elías Gonzalez, who being in Sonora, was induced to remain there. José Antonio Arcé took his place as ruler in Chihuahua. In 1829, González became general commander of Chihuahua, when his term of office on the west coast expired. Arcé was less of a yorkino than his confrere of Durango. Although unable to resist the popular demand for the expulsion of the Spaniards, he soon quarreled with the legislature, which declared itself firmly for Guerrero, and announcing his support of Bustamante's revolution, he suspended, in March 1830, eight members of that body, the vice-governor, and several other officials, and expelled them from the state. The course thus outlined was followed by Governor José Isidro Madero, who succeeded in 1830, associated with J. J. Calvo as general commander, stringent laws being issued against secret societies, which were supposed to be the main spring to the anti-clerical feeling among liberals.

The state seemed at relative calm compared to the rest of the country due to its close ties to the United States until 1841. In 1843 the possibility of war was anticipated by the state government and it began to reinforce the defense lines along the political boundary with Texas. Supplies of weapons were sent to fully equip the military and took steps to improve efficiency at the presidios. Later, the Regimen for the Defenders of the Border were organized by the state which were made up of: light cavalry, four squads of two brigades, and a small force of 14 men and 42 officials at the price of 160,603 pesos per year. During the beginning of the 1840s, private citizens took it upon themselves to stop the commercial caravans of supplies from the United States, but being so far away from the large suppliers in central Mexico the caravan was allowed to continue in March 1844. Continuing to anticipate a war, the state legislature on July 11, 1846 by decree enlisted 6,000 men to serve along the border; during that time Ángel Trías quickly rose to power by portraying zealous anti-American rhetoric. Trías took the opportunity to dedicate important state resources to gain economic concessions from the people and loans from many municipalities in preparation to defend the state; he used all the money he received to equip and organize a large volunteer militia. Ángel Trías took measures for state self-dependence in regards to state militia due to the diminishing financial support from the federal government.

Santa Bárbara became the launching place for expeditions into New Mexico by Spanish conquistadors like: Antonio de Espejo, Gaspar Castaño, Antonio Gutiérrez de Umaña, Francisco Leyba de Bonilla, and Vicente de Zaldívar. Several expeditions were led to find a shorter route from Santa Barbara to New Mexico. In April 1598, Juan de Oñate finally found a short route from Santa Barbara to New Mexico which came to be called El Paso del Norte (The Northern Pass). The discovery of El Paso Del Norte was important for the expansion of El Camino Real de Tierra Adentro (The Inner Land Royal Road) to link Spanish settlements in New Mexico to Mexico City; El Camino Real de Tierra Adentro facilitated transport of settlers and supplies to New Mexico.

Hidalgo is hailed as the Father of the Nation even though it was Agustin de Iturbide and not Hidalgo who achieved Mexican Independence in 1821. Shortly after gaining independence, the day to celebrate it varied between September 16, the day of Hidalgo's Grito, and September 27, the day Iturbide rode into Mexico City to end the war. Later, political movements would favor the more liberal Hidalgo over the conservative Iturbide, so that eventually September 16, 1810 became the officially recognized day of Mexican independence. The reason for this is that Hidalgo is considered to be "precursor and creator of the rest of the heroes of the (Mexican War of) Independence." Hidalgo has become an icon for Mexicans who resist tyranny in the country. Diego Rivera painted Hidalgo's image in half a dozen murals. José Clemente Orozco depicted him with a flaming torch of liberty and considered the painting among his best work. David Alfaro Siqueiros was commissioned by San Nicolas University in Morelia to paint a mural for a celebration commemorating the 200th anniversary of Hidalgo's birth. The town of his parish was renamed Dolores Hidalgo in his honor and the state of Hidalgo was created in 1869. Every year on the night of 15–16 September, the president of Mexico re-enacts the Grito from the balcony of the National Palace. This scene is repeated by the heads of cities and towns all over Mexico. The remains of Miguel Hidalgo y Costilla lie in the column of the Angel of Independence in Mexico City. Next to it is a lamp lit to represent the sacrifice of those who gave their lives for Mexican Independence.

On February 8, 1847, Doniphan continued his march with 924 men mostly from Missouri; he accompanied a train of 315 wagons of a large commercial caravan heading to the state capital. Meanwhile, the Mexican forces in the state had time to prepare a defense against the Americans. About 20 miles (32 km) north of the capital where two mountain ranges join from east to west is the only pass into the capital; known as Sacramento Pass, this point is now part of present-day Chihuahua City. The Battle of Sacramento was the most important battle fought in the state of Chihuahua because it was the sole defense for the state capital. The battle ended quickly because of some devastating defensive errors from the Mexican forces and the ingenious strategic moves by the American forces. After their loss at the Battle of Sacramento, the remaining Mexican soldiers retreated south, leaving the city to American occupation. Almost 300 Mexicans were killed in the battle, as well as almost 300 wounded. The Americans also confiscated large amounts of Mexican supplies and took 400 Mexican soldiers prisoners of war. American forces maintained an occupation of the state capital for the rest of the Mexican–American War.

On July 20, Governor Elorriaga was reinstated, and Baca along with the legislative minority were brought back to form a new legislature, which met on September 1. Chihuahua showed no desire to imitate the revolutionary movement and Urrea prepared to invade the state. Comandante-general J.J.Calvo threatened to retaliate, and a conflict seemed imminent.

Under threat from the conservative forces, Governor Terrazas was deposed, and the state legislature proclaimed martial law in the state in April 1864 and established Jesús José Casavantes as the new governor. In response, José María Patoni decided to march to Chihuahua with presidential support. Meanwhile, Maximilian von Habsburg, a younger brother of the Emperor of Austria, was proclaimed Emperor Maximilian I of Mexico on April 10, 1864 with the backing of Napoleon III and a group of Mexican conservatives. Before President Benito Juárez was forced to flee, Congress granted him an emergency extension of his presidency, which would go into effect in 1865 when his term expired, and last until 1867. At the same time, the state liberals and conservatives compromised to allow the popular Ángel Trías take the governorship; by this time the French forces had taken control over the central portions of the country and were making preparations to invade the northern states.

The state united behind the Plan of Ayutla and ratified the new constitution in 1855. The state was able to survive through the Reform War with minimal damage due to the large number of liberal political figures. The 1858 conservative movement did not succeed in the state even after the successful military campaign of the conservative Zuloaga with 1,000 men occupied the cities of Chihuahua and Parral. In August 1859, Zuloaga and his forces were defeated by the liberal Orozco and his forces; Orozco soon after deposed the state governor, but had to flee to Durango two months later. In the late 1860s the conservative General Cajen briefly entered the state after his campaign through the state of Jalisco and helped establish conservative politicians and ran out the liberal leaders Jesús González Ortega and José María Patoni. Cajen took possession of the state capital and established himself as governor; he brooked no delay in uniting a large force to combat the liberal forces which he defeated in La Batalla del Gallo. Cajen attained several advantages over the liberals within the state, but soon lost his standing due to a strong resurgence of the liberal forces within the state. The successful liberal leaders José María Patoni of Durango and J.E. Muñoz of Chihuahua quickly strengthened their standing by limiting the political rights of the clergy implementing the presidential decree. The state elected General Luis Terrazas, a liberal leader, as governor; he would continue to fight small battles within the state to suppress conservative uprisings during 1861.

After running imperial military affairs in the states of Coahuila and Durango, General Agustín Enrique Brincourt made preparations to invade the state of Chihuahua. On July 8, 1865 Brincourt crossed the Nazas River in northern Durango, heading toward Chihuahua. On July 22 Brincourt crossed the banks of Río Florido into Ciudad Jiménez; one day later he arrived at Valle de Allende where he sent Colonel Pyot with a garrison to take control of Hidalgo del Parral. Brincourt continued through Santa Rosalia de Camargo and Santa Cruz de Rosales. President Juárez remained in the state capital until August 5, 1865 when he left for El Paso del Norte (present-day Ciudad Juárez) due to evidence that the French were to attack the city. On the same day, the President named General Manuel Ojinaga the new governor and placed him in charge of all the republican forces. Meanwhile, General Villagran surprised the imperial forces in control of Hidalgo de Parral; after a short two-hour battle, Colonel Pyot was defeated and forced to retreat. At the Battle of Parral, the French lost 55 men to the Republican forces. On August 13, 1865, the French forces with an estimated 2,500 men arrived at the outskirts of Chihuahua City, and on August 15, 1865, General Brincourt defeated the republican forces, taking control of the state capital. Brincourt designated Tomás Zuloaga as Prefect of Chihuahua. Fearing the French would continue their campaign to El Paso del Norte, President Juárez relocated to El Carrizal, a secluded place in the mountains near El Paso del Norte, in August 1865, . It would have been easy for the French forces to continue in pursuit of President Juárez across the border, but they feared altercations with American forces. General François Achille Bazaine ordered the French troops to retreat back to the state of Durango after only reaching a point one days travel north of Chihuahua City. General Brincourt asked for 1,000 men to be left behind to help maintain control over the state, but his request was denied. After the death of General Ojinaga, the Republican government declared General Villagran in charge of the fight against the Imperial forces. The French left the state on October 29, 1865. President Juárez returned to Chihuahua City on November 20, 1865 and remained in the city until December 9, 1865 when he returned to El Paso del Norte.

General Aguirre moved to the deserts of the southeastern portion of the state and defeated the French forces in Parral, led by Colonel Cottret. By the middle of 1866, the state of Chihuahua was declared free of enemy control; Parral was the last French stronghold within the state. On June 17, 1866, President Juárez arrived in Chihuahua City and remained in the capital until December 10, 1866. During his two years in the state of Chihuahua, President Juárez passed ordinances regarding the rights of adjudication of property and nationalized the property of the clergy. The distance of the French forces and their allies allowed the Ministry of War, led by General Negrete, to reorganize the state's national guard into the Patriotic Battalion of Chihuahua, which was deployed to fight in the battle of Matamoros, Tamaulipas against the French. After a series of major defeats and an escalating threat from Prussia, France began pulling troops out of Mexico in late 1866. Disillusioned with the liberal political views of Maximilian, the Mexican conservatives abandoned him, and in 1867 the last of the Emperor's forces were defeated. Maximilian was sentenced to death by a military court; despite national and international pleas for amnesty, Juárez refused to commute the sentence.

The United States Congress declared war on Mexico on May 13, 1846 after only having a few hours to debate. Although President José Mariano Paredes's issuance of a manifesto on May 23 is sometimes considered the declaration of war, Mexico officially declared war by Congress on July 7. After the American invasion of New Mexico, Chihuahua sent 12,000 men led by Colonel Vidal to the border to stop the American military advance into the state. The Mexican forces being impatient to confront the American forces passed beyond El Paso del Norte about 20 miles (32 km) north along the Rio Grande. The first battle that Chihuahua fought was the battle of El Bracito; the Mexican forces consisting of 500 cavalry and 70 infantry confronted a force of 1,100–1,200 Americans on December 25, 1846. The battle ended badly by the Mexican forces that were then forced to retreat back into the state of Chihuahua. By December 27, 1846, the American forces occupied El Paso Del Norte.

Despite the internal stability (known as the paz porfiriana), modernization, and economic growth in Mexico during the Porfiriato from 1876 to 1910, many across the state became deeply dissatisfied with the political system. When Díaz first ran for office, he committed to a strict “No Re-election” policy in which he disqualified himself to serve consecutive terms. Eventually backtracking on many of his initial political positions Díaz became a de facto dictator. Díaz became increasingly unpopular due to brutal suppression of political dissidents by using the Rurales and manipulating the elections to solidify his political machine. The working class was frustrated with the Díaz regime due to the corruption of the political system that had increased the inequality between the rich and poor. The peasants felt disenfranchised by the policies that promoted the unfair distribution of land where 95% of the land was owned by the top 5%.

In response to Madero's letter to action, Pascual Orozco (a wealthy mining baron) and Chihuahua Governor Abraham González formed a powerful military union in the north, taking military control of several northern Mexican cities with other revolutionary leaders, including Pancho Villa. Against Madero's wishes, Orozco and Villa fought for and won Ciudad Juárez. After militias loyal to Madero defeated the Mexican federal army, on May 21, 1911, Madero signed the Treaty of Ciudad Juárez with Díaz. It required that Díaz abdicate his rule and be replaced by Madero. Insisting on a new election, Madero won overwhelmingly in late 1911, and he established a liberal democracy and received support from the United States and popular leaders such as Orozco and Villa. Orozco eventually became disappointed with the Madero's government and led a rebellion against him.

The situation became so tense that war with the United States seemed imminent. On April 22, 1914, on the initiative of Felix A. Sommerfeld and Sherburne Hopkins, Pancho Villa traveled to Juárez to calm fears along the border and asked President Wilson's emissary George Carothers to tell "Señor Wilson" that he had no problems with the American occupation of Veracruz. Carothers wrote to Secretary William Jennings Bryan: "As far as he was concerned we could keep Vera Cruz [sic] and hold it so tight that not even water could get in to Huerta and . . . he could not feel any resentment". Whether trying to please the U.S. government or through the diplomatic efforts of Sommerfeld and Carothers, or maybe as a result of both, Villa stepped out from under Carranza’s stated foreign policy.

The state of Chihuahua is the largest state in the country and is known as El Estado Grande (The Big State); it accounts for 12.6% of the land of Mexico. The area is landlocked by the states of Sonora to the west, Sinaloa to the south-west, Durango to the south, and Coahuila to the east, and by the U.S. states of Texas to the northeast and New Mexico to the north. The state is made up of three geologic regions: Mountains, Plains-Valleys, and Desert, which occur in large bands from west to east. Because of the different geologic regions there are contrasting climates and ecosystems.

The climate in the state depends mainly in the elevation of the terrain. According to Köppen climate classification the state has five major climate zones. The Sierra Madre Occidental dominates the western part of the state; there are two main climates in this area: Subtropical Highland (Cfb) and Humid Subtropical (Cwa). There are some microclimates in the state due to the varying topology mostly found in the western side of the state. The two best known microclimates are: Tropical savanna climate (Aw) in deep canyons located in the extreme southern part of the state; Continental Mediterranean climate (Dsb) in the extremely high elevations of the Sierra Madre Occidental. Satellite image to the right shows the vegetation is much greener in the west because of the cooler temperatures and larger amounts of precipitation as compared to the rest of the state.

Villa and Carranza had different political goals causing Villa to become an enemy of Carranza. After Carranza took control in 1914, Villa and other revolutionaries who opposed him met at what was called the Convention of Aguascalientes. The convention deposed Carranza in favor of Eulalio Gutiérrez. In the winter of 1914 Villa's and Zapata's troops entered and occupied Mexico City. Villa was forced from the city in early 1915 and attacked the forces of Gen. Obregón at the Battle of Celaya and was badly defeated in the bloodiest battle of the revolution, with thousands dead. With the defeat of Villa, Carranza seized power. A short time later the United States recognized Carranza as president of Mexico. Even though Villa's forces were badly depleted by his loss at Celaya, he continued his fight against the Carranza government. Finally, in 1920, Obregón—who had defeated him at Celaya—finally reached an agreement with Villa end his rebellion.

The plains at the foot of the Sierra Madre Occidental is an elongated mesa known as Altiplanicie Mexicana that exhibits a steppe climate and serves as a transition zone from the mountain climate in the western part of the state to the desert climate in the eastern side of the state. The steppe zone accounts for a third of the state's area, and it experiences pronounced dry and wet seasons. The pronounced rainy season in the steppe is usually observed in the months of July, August, and September. The steppe also encounters extreme temperatures that often reach over 100 °F in the summer and drop below 32 °F in the winter. The steppe zone is an important agriculture zone due to an extensive development of canals exploiting several rivers that flow down from the mountains. The steppe zone is the most populated area of the state.

The state has a great diversity due to the large number of microclimates found and dramatic varying terrain. The flora throughout the Sierra Madre Occidental mountain range varies with elevation. Pine (Pinus) and oak (Quercus) species are usually found at an elevation of 2,000 m (6,560 ft) above sea level. The most common species of flora found in the mountains are: Pinus, Quercus, Abies, Ficus, Vachellia, Ipomoea, Acacia, Lysiloma, Bursera, Vitex, Tabebuia, Sideroxylon, Cordia, Fouquieria, Pithecellobium. The state is home to one of the largest variation species of the genus Pinus in the world. The lower elevations have a steppe vegetation with a variety of grasses and small bushes. Several species of Juniperus dot the steppe and the transition zone.

The state has one city with a population exceeding one million: Ciudad Juárez. Ciudad Juárez is ranked eighth most populous city in the country and Chihuahua City was ranked 16th most populous in Mexico. Chihuahua (along with Baja California) is the only state in Mexico to have two cities ranked in the top 20 most populated. El Paso and Ciudad Juárez comprise one of the largest binational metropolitan areas in the world with a combined population of 2.4 million. In fact, Ciudad Juárez is one of the fastest growing cities in the world in spite of the fact that it is "the most violent zone in the world outside of declared war zones". For instance, a few years ago the Federal Reserve Bank of Dallas published that in Ciudad Juárez "the average annual growth over the 10-year period 1990–2000 was 5.3 percent. Juárez experienced much higher population growth than the state of Chihuahua and than Mexico as a whole". Chihuahua City has one of the highest literacy rates in the country at 98%; 35% of the population is aged 14 or below, 60% 15-65, and 5% over 65. The growth rate is 2.4%.

The French forces tried to subdue and capture the liberal government based in Saltillo. On September 21, 1864, José María Patoni and Jesús González Ortega lost against the French forces at the Battle of Estanzuelas; the supreme government led by President Juárez was forced to evacuate the city of Saltillo and relocate to Chihuahua. Juárez stopped in Ciudad Jiménez, Valle de Allende, and Hidalgo de Parral, in turn. He decreed Parral the capital of Mexico from October 2–5, 1864. Perceiving the threat from the advancing French forces, the president continued his evacuation through Santa Rosalía de Camargo, Santa Cruz de Rosales, and finally Chihuahua, Chihuahua. On October 12, 1864, the people of the state gave President Juárez an overwhelmingly supportive reception, led by Governor Ángel Trías.

President Benito Juárez was re-elected in the general election of 1867 in which he received strong liberal support, especially in Chihuahua. Luis Terrazas was confirmed by the people of Chihuahua to be governor of the state. But soon after the election, President Juárez had another crisis on his hands; the Juárez administration was suspected to be involved in the assassination of the military chief José María Patoni executed by General Canto in August 1868. General Canto turned himself over to Donato Guerra. Canto was sentenced to death, but later his sentence changed to 10 years imprisonment. The sense of injustice gave rise to a new rebellion in 1869 that threatened the federal government. In response, the Juárez administration took drastic measures by temporarily suspending constitutional rights, but the governor of Chihuahua did not support this action. Hostilities continued to increase especially after the election of 1871 which was perceived to be fraudulent. A new popular leader arose among the rebels, Porfirio Díaz. The federal government was successful in quelling rebellions in Durango an Chihuahua. On July 18, 1872, President Juárez died from a heart attack; soon after, many of his supporters ceased the fighting. Peace returned to Chihuahua and the new government was led by Governor Antonio Ochoa (formerly a co-owner of the Batopilas silver mines) in 1873 after Luis Terrazas finished his term in 1872.

The Díaz administration made political decisions and took legal measures that allowed the elite throughout Mexico to concentrate the nation's wealth by favoring monopolies. During this time, two-fifths of the state's territory was divided among 17 rich families which owned practically all of the arable land in Chihuahua. The state economy grew at a rapid pace during the Porfiriato; the economy in Chihuahua was dominated by agriculture and mining. The Díaz administration helped Governor Luis Terrazas by funding the Municipal Public Library in Chihuahua City and passing a federal initiative for the construction of the railroad from Chihuahua City to Ciudad Júarez. By 1881, the Central Mexican Railroad was completed which connected Mexico City to Ciudad Juárez. In 1883 telephone lines were installed throughout the state, allowing communication between Chihuahua City and Aldama. By 1888 the telephone services were extended from the capital to the cites of Julimes, Meoqui, and Hidalgo del Parral; the telecommunication network in the state covered an estimated 3,500 kilometers. The need of laborers to construct the extensive infrastructure projects resulted in a significant Asian immigration, mostly from China. Asian immigrants soon become integral to the state economy by opening restaurants, small grocery stores, and hotels. By the end of the Terrazas term, the state experienced an increase in commerce, mining, and banking. When the banks were nationalized, Chihuahua became the most important banking state in Mexico.

The main mountain range in the state is the Sierra Madre Occidental reaching a maximum altitude of 10,826 ft (3,300 m) known as Cerro Mohinora. Mountains account for one third of the state's surface area which include large coniferous forests. The climate in the mountainous regions varies Chihuahua has more forests than any other state in Mexico making the area a bountiful source of wood; the mountainous areas are rich in minerals important to Mexico's mining industry. Precipitation and temperature in the mountainous areas depends on the elevation. Between the months of November and March snow storms are possible in the lower elevations and are frequent in the higher elevations. There are several watersheds located in the Sierra Madre Occidental all of the water that flows through the state; most of the rivers finally empty into the Río Grande. Temperatures in some canyons in the state reach over 100 °F in the summer while the same areas rarely drop below 32 °F in the winter. Microclimates found in the heart of the Sierra Madre Occidental in the state could be considered tropical, and wild tropical plants have been found in some canyons. La Barranca del Cobre, or Copper Canyon, a spectacular canyon system larger and deeper than the Grand Canyon; the canyon also contains Mexico's two tallest waterfalls: Basaseachic Falls and Piedra Volada.

During the Mexican Revolution, Álvaro Obregón invited a group of Canadian German-speaking Mennonites to resettle in Mexico. By the late 1920s, some 7,000 had immigrated to Chihuahua State and Durango State, almost all from Canada, only a few from the U.S. and Russia. Today, Mexico accounts for about 42% of all Mennonites in Latin America. Mennonites in the country stand out because of their light skin, hair, and eyes. They are a largely insular community that speaks a form of German and wear traditional clothing. They own their own businesses in various communities in Chihuahua, and account for about half of the state's farm economy, excelling in cheese production.

Nueva Vizcaya (New Biscay) was the first province of northern New Spain to be explored and settled by the Spanish. Around 1528, a group of Spaniard explorers, led by Álvar Núñez Cabeza de Vaca, first entered the actual territory of what is now Chihuahua. The conquest of the territory lasted nearly one century, and encountered fierce resistance from the Conchos tribe, but the desire of the Spanish Crown to transform the region into a bustling mining center led to a strong strategy to control the area.

Hidalgo was turned over to the Bishop of Durango, Francisco Gabriel de Olivares, for an official defrocking and excommunication on July 27, 1811. He was then found guilty of treason by a military court and executed by firing squad on July 30 at 7 in the morning. Before his execution, he thanked his jailers, Private Soldiers Ortega and Melchor, in letters for their humane treatment. At his execution, Hidalgo placed his right hand over his heart to show the riflemen where they should aim. He also refused the use of a blindfold. His body, along with the bodies of Allende, Aldama and José Mariano Jiménez were decapitated, and the heads were put on display on the four corners of the Alhóndiga de Granaditas in Guanajuato. The heads remained there for ten years until the end of the Mexican War of Independence to serve as a warning to other insurgents.

Because of the general instability of the federal government during 1828, the installation of the new legislature did not take place until the middle of the following year. It was quickly dissolved by Governor Santiago de Baca Ortiz, who replaced it with a more pronounced Yorkino type. When Guerrero's liberal administration was overthrown in December, Gaspar de Ochoa aligned with Anastasio Bustamante, and in February 1830, organized an opposition group that arrested the new governor, F. Elorriaga, along with other prominent Yorkinos. He then summoned the legislature, which had been dissolved by Baca. The civil and military authorities were now headed by J. A.

During the American occupation of the state, the number of Indian attacks was drastically reduced, but in 1848 the attacks resumed to such a degree that the Mexican officials had no choice but to resume military projects to protect Mexican settlements in the state. Through the next three decades the state faced constant attacks from indigenous on Mexican settlements. After the occupation the people of the state were worried about the potential attack from the hostile indigenous tribes north of the Rio Grande; as a result a decree on July 19, 1848, the state established 18 military colonies along the Rio Grande. The new military colonies were to replace the presidios as population centers to prevent future invasions by indigenous tribes; these policies remained prominent in the state until 1883. Eventually the state replaced the old state security with a state policy to form militias organized with every Mexican in the state capable to serve between the ages of 18 and 55 to fulfill the mandate of having six men defending for every 1000 residents.

The liberal political forces maintained strong control over the state government until shortly after the French Intervention which turned the tables in favor to the conservative forces once again. The intervention had serious repercussions for the state of Chihuahua. President Juárez, in an effort to organize a strong defense against the French, decreed a list of national guard units that every state had to contribute to the Ministry of War and the Navy; Chihuahua was responsible for inducting 2,000 men. Regaining power, Governor Luis Terrazas assigned the First Battalion of Chihuahua for integration into the national army led by General Jesús González Ortega; the battalion was deployed to Puebla. After the defeat of the army in Puebla, the Juárez administration was forced to abandon Mexico City; the president retreated further north seeking refuge in the state of Chihuahua.

President Juárez once again based his government in the state of Chihuahua and it served as the center for the resistance against the French invasion throughout Mexico. On March 25, 1866, a battle ensued in the Plaza de Armas in the center of Chihuahua City between the French imperial forces that were guarding the plaza and the Republican forces led by General Terrazas. Being completely caught off guard, the French imperial forces sought refuge by bunkering themselves in the Cathedral of the Holy Cross, Our Lady of Regla, and St Fancis of Assisi and made it almost impossible to penetrate their defenses. General Terrazas then decided to fire a heavy artillery barrage with 8 kg cannonballs. The first cannon fired hit a bell in the tower of the church, instantly breaking it in half; soon after, 200 men of the imperial army forces surrendered. The republican forces had recovered control over the state capital. The bell in the church was declared a historical monument and can be seen today in the Cathedral. By April 1866, the state government had established a vital trading route from Chihuahua City to San Antonio, Texas; the government began to replenish their supplies and reinforce their fight against the Imperial forces.

The officials in Mexico City reduced the price of corn from six cents to two cents a pound. The northern portion of the state continued to decline economically which led to another revolt led by G. Casavantes in August 1879; Governor Trías was accused of misappropriation of funds and inefficient administration of the state. Casavantes took the state capital and occupied it briefly; he was also successful in forcing Governor Trías to exile. Shortly afterwards, the federal government sent an entourage led by Treviño; Casavantes was immediately ordered to resign his position. Casavantes declared political victory as he was able to publicly accuse and depose Governor Trías. At the same time the states of Durango and Coahuila had a military confrontation over territorial claims and water rights; this altercation between the state required additional federal troops to stabilize the area. Later a dispute ensued again among the states of Coahuila, Durango, and Chihuahua over the mountain range area known as Sierra Mojada, when large deposits of gold ore was discovered. The state of Chihuahua officially submitted a declaration of protest in May 1880 that shortly after was amicably settled.

A handful of families owned large estates (known as haciendas) and controlled the greater part of the land across the state while the vast majority of Chihuahuans were landless. The state economy was largely defined by ranching and mining. At the expense of the working class, the Díaz administration promoted economic growth by encouraging investment from foreign companies from the United Kingdom, France, Imperial Germany and the United States. The proletariat was often exploited, and found no legal protection or political recourse to redress injustices.

On March 26, 1913, Venustiano Carranza issued the Plan de Guadalupe, which refused to recognize Huerta as president and called for war between the two factions. Soon after the assassination of President Madero, Carranza returned to Mexico to fight Huerta, but with only a handful of comrades. However, by 1913 his forces had swelled into an army of thousands, called the División del Norte (Northern Division). Villa and his army, along with Emiliano Zapata and Álvaro Obregón, united with Carranza to fight against Huerta. In March 1914 Carranza traveled to Ciudad Juárez, which served as rebellion's capital for the remainder of the struggle with Huerta. In April 1914 U.S. opposition to Huerta had reached its peak, blockading the regime's ability to resupply from abroad. Carranza trying to keep his nationalistic credentials threatened war with the United States.

The desert zone also accounts for about a third of the state's surface area. The Chihuahuan Desert is an international biome that also extends into the neighboring Mexican state of Coahuila and into the U.S. states of Texas and New Mexico. The desert zone is mainly of flat topography with some small mountain ranges that run north to south. The desert in the state varies slightly with a small variant in climate. The lower elevations of the desert zone are found in the north along the Rio Grande which experience hotter temperatures in the summer and winter while the southern portion of the desert zone experiences cooler temperatures due to its higher elevation. The Samalayuca dunes cover an area of about 150 km2; it is an impressive site of the Chihuahuan Desert and is a protected area by the state due to unique species of plants and animals.

The desert zone accounts for how much of the state's surface area?

about a third

The Chihuahuan Desert also extends into which neighboring Mexican state?

Coahuila

The desert zone's topography is mostly what shape?

flat

Lower elevations and higher temperature are found in which region of the state; north, south, east, or west?

north

Which well-known river runs in the northern part of the state?

Rio Grande


The fauna in the state is just as diverse as the flora and varies greatly due to the large contrast in climates. In the mountain zone of the state the most observed mammals are: Mexican fox squirrel (Sciurus nayaritensis), antelope jackrabbit (Lepus alleni), raccoon (Procyon lotor), hooded skunk (Mephitis macroura), wild boar (Sus scrofa), collared peccary (Pecari tajacu), white-tailed deer (Odocoileus virginianus), mule deer Odocoileus hemionus, American bison Bison bison, cougar (Puma concolor), eastern cottontail Sylvilagus floridanus, North American porcupine Erethizon dorsatum, bobcat Lynx rufus, Mexican wolf Canis lupus baileyi, and coyote Canis latrans. American black bear Ursus americanus is also found but in very small numbers. The Mexican wolf, once abundant, has been extirpated. The main cause of degradation has been grazing. Although there are many reptilian species in the mountains the most observed species include: Northern Mexican pine snake, Pituophis deppei jani, Texas horned lizard (Phrynosoma cornutum), rock rattlesnake (Crotalus lepidus), black-tailed rattlesnake (Crotalus molossus), and plateau tiger salamander Ambystoma velasci, one of possibly many amphibians to be found in the mountains.

American black bear

The main cause of degradation has been what?

grazing

What type of snake is most popular in the region with many different species?

The last census in Mexico that asked for an individual's race, which was taken in 1921, indicated that 50.09% of the population identified as Mestizo (mixed Amerindian and European descent). The second-largest group was whites at 36.33% of the population. The third-largest group was the "pure indigenous" population, constituting 12.76% of the population. The remaining 0.82% of the population of Chihuahua was considered "other", i.e., neither Mestizo, indigenous, nor white. The most important indigenous tribes of the state of Chihuahua are:

During the 1990s after NAFTA was signed, industrial development grew rapidly with foreign investment. Large factories known as maquiladoras were built to export manufactured goods to the United States and Canada. Today, most of the maquiladoras produce electronics, automobile, and aerospace components. There are more than 406 companies operating under the federal IMMEX or Prosec program in Chihuahua. The large portion of the manufacturing sector of the state is 425 factories divided into 25 industrial parks accounting for 12.47% of the maquiladoras in Mexico, which employ 294,026 people in the state. While export-driven manufacturing is one of the most important components of the state's economy, the industrial sector is quite diverse and can be broken down into several sectors, which are: electronics, agro-industrial, wood base manufacturing, mineral, and biotech. Similar to the rest of the country, small businesses continue to be the foundation of the state’s economy. Small business employs the largest portion of the population.[citation needed]

Shias believe that Imamah is of the Principles of Faith (Usul al-Din).As the verse 4:165 of quran expresses the necessity to the appointment of the prophets; so after the demise of the prophet who will play the role of the prophet; till the people have not any plea against Allah.So the same logic that necessitated the assignment of prophets also is applied for Imamah.That is Allah Must assign someone similar to prophet in his attributes and Ismah as his successor to guide the people without any deviation in religion. They refer to the verse (...This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion...) 5:3 of Quran which was revealed to the prophet when he appointed Ali as his successor at the day of Ghadir Khumm.

Imamah (Arabic: إمامة) is the Shia Islam doctrine (belief) of religious, spiritual and political leadership of the Ummah. The Shia believe that the Imams are the true Caliphs or rightful successors of Muhammad, and further that Imams are possessed of divine knowledge and authority (Ismah) as well as being part of the Ahl al-Bayt, the family of Muhammad. These Imams have the role of providing commentary and interpretation of the Quran as well as guidance to their tariqa followers as is the case of the living Imams of the Nizari Ismaili tariqah.

What is the Shia Islam doctrine called?

Imamah

Who do the Shia believe are the true successors of Muhammad?

Imams

What is the role of Imams?

providing commentary and interpretation of the Quran

Who do the Shia believe are possessed of divine knowledge and authority?

Imams


Within Shia Islam (Shiism), the various sects came into being because they differed over their Imams' successions, just as the Shia - Sunni separation within Islam itself had come into being from the dispute that had arisen over the succession to Muhammad. Each succession dispute brought forth a different tariqah (literal meaning 'path'; extended meaning 'sect') within Shia Islam. Each Shia tariqah followed its own particular Imam's dynasty, thus resulting in different numbers of Imams for each particular Shia tariqah. When the dynastic line of the separating successor Imam ended with no heir to succeed him, then either he (the last Imam) or his unborn successor was believed to have gone into concealment, that is, The Occultation.

It is forbidden for the Divine Leader not to be from the family of Muhammad.[citation needed] According to Ali al-Ridha, since it is obligatory to obey him, there should be a sign to clearly indicate the Divine Leader. That sign is his well-known ties of kinship with Muhammad and his clear appointment so that the people could distinguish him from others, and be clearly guided toward him. Otherwise others are nobler than Muhammad's offspring and they are to be followed and obeyed; and the offspring of Muhammad are obedient and subject to the offspring of Muhammad’s enemies such as Abi Jahl or Ibn Abi Ma’eet.[original research?] However, Muhammad is much nobler than others to be in charge and to be obeyed. Moreover, once the prophethood of Muhammad is testified they would obey him, no one would hesitate to follow his offspring and this would not be hard for anyone. While to follow the offspring of the corrupted families is difficult.[original research?] And that is maybe why the basic characteristic of Muhammad and other prophets was their nobility.[original research?] For none of them, it is said, were originated from a disgraced family.[citation needed] It is believed that all Muhammad's ancestors up to Adam were true Muslims. [a][citation needed] Jesus was also from a pious family, as it is mentioned in Quran that after his birth, people said to Mary: O sister of Aaron, your father was not a man of evil, nor was your mother unchaste."[b][improper synthesis?]

The word "Imām" denotes a person who stands or walks "in front". For Sunni Islam, the word is commonly used to mean a person who leads the course of prayer in the mosque. It also means the head of a madhhab ("school of thought"). However, from the Shia point of view this is merely the basic understanding of the word in the Arabic language and, for its proper religious usage, the word "Imam" is applicable only to those members of the house of Muhammad designated as infallible by the preceding Imam.

Although all these different Shia tariqahs belong to the Shia group (as opposed to the Sunni group) in Islam, there are major doctrinal differences between the main Shia tariqahs. After that there is the complete doctrinal break between all the different Shia tariqahs whose last Imams have gone into Occultation and the Shia Nizari Ismailis who deny the very concept of Occultation. The Shia Nizari Ismailis by definition have to have a present and living Imam until the end of time.[citation needed] Thus if any living Nizari Ismaili Imam fails to leave behind a successor after him then the Nizari Ismailism’s cardinal principle would be broken and it’s very raison d'être would come to an end.

Shia

What has happened to some of the Shia tariqahs last Imams?

Occultation

According to Ismā‘īlīsm, Allah has sent "seven" great prophets known as “Nātıq” (Spoken) in order to disseminate and improve his Dīn of Islam. All of these great prophets has also one assistant known as “Sāmad (Silent) Imām”. At the end of each seven “Sāmad” silsila, one great “Nātıq” (Spoken) has ben sent in order to reimprove the Dīn of Islam. After Adam and his son Seth, and after six “Nātıq” (Spoken) – “Sāmad” (Silent) silsila (Noah–Shem), (Abraham–Ishmael), (Moses–Aaron), (Jesus–Simeon), (Muhammad bin ʿAbd Allāh–Ali ibn Abu Tālib); the silsila of “Nātıqs and Sāmads have been completed with (Muhammad bin Ismā‘īl as-ṣaghīr (Maymûn’ûl-Qaddāh)–ʿAbd Allāh Ibn-i Maymûn and his sons).

The Shia tariqah with a majority of adherents are the Twelvers who are commonly known as the "Shia". After that come the Nizari Ismailis commonly known as the Ismailis; and then come the Mustalian Ismailis commonly known as the "Bohras" with further schisms within their Bohri tariqah. The Druze tariqah (very small in number today) initially were of the Fatimid Ismailis and separated from them (the Fatimid Ismailis) after the death of the Fatimid Imam and Caliph Hakim Bi Amrillah. The Shia Sevener tariqah no longer exists. Another small tariqah is the Zaidi Shias, also known as the Fivers and who do not believe in The Occultation of their last Imam.

During the Minor Occultation (Ghaybat al-Sughrá), it is believed that al-Mahdi maintained contact with his followers via deputies (Arab. an-nuwāb al-arbaʻa or "the Four Leaders"). They represented him and acted as agents between him and his followers. Whenever the believers faced a problem, they would write their concerns and send them to his deputy. The deputy would ascertain his verdict, endorse it with his seal and signature and return it to the relevant parties. The deputies also collected zakat and khums on his behalf.

The Ismailis differ from Twelvers because they had living imams for centuries after the last Twelver Imam went into concealment. They followed Isma'il ibn Jafar, elder brother of Musa al-Kadhim, as the rightful Imam after his father Ja'far al-Sadiq. The Ismailis believe that whether Imam Ismail did or did not die before Imam Ja'far, he had passed on the mantle of the imamate to his son Muḥammad ibn Ismail as the next imam. Thus, their line of imams is as follows (the years of their individual imamats during the Common Era are given in brackets):

The line of imams of the Mustali Ismaili Shia Muslims (also known as the Bohras/Dawoodi Bohra) continued up to Aamir ibn Mustali. After his death, they believe their 21st Imam Taiyab abi al-Qasim went into a Dawr-e-Satr (period of concealment) that continues to this day. In the absence of an imam they are led by a Dai-al-Mutlaq (absolute missionary) who manages the affairs of the Imam-in-Concealment until re-emergence of the Imam from concealment. Dawoodi Bohra's present 53rd Da'i al-Mutlaq is His Holiness Syedna Mufaddal Saifuddin (TUS) who succeeded his predessor the 52nd Da'i al-Mutlaq His Holiness Syedna Mohammed Burhanuddin (RA). Furthermore, there has been a split in the Dawoodi Bohra sect which has led to the formation of Qutbi Bohra sect which was formed and led by Khuzaima Qutbuddin.

All Muslims believe that Muhammad had said: "To whomsoever I am Mawla, Ali is his Mawla." This hadith has been narrated in different ways by many different sources in no less than 45 hadith books[citation needed] of both Sunni and Shia collections. This hadith has also been narrated by the collector of hadiths, al-Tirmidhi, 3713;[citation needed] as well as Ibn Maajah, 121;[citation needed] etc. The major point of conflict between the Sunni and the Shia is in the interpretation of the word 'Mawla'. For the Shia the word means 'Lord and Master' and has the same elevated significance as when the term had been used to address Muhammad himself during his lifetime. Thus, when Muhammad actually (by speech) and physically (by way of having his closest companions including Abu Bakr, Umar and Uthman [the three future Caliphs who had preceded Ali as Caliph] publicly accept Ali as their Lord and Master by taking Ali's hand in both of theirs as token of their allegiance to Ali) transferred this title and manner of addressing Ali as the Mawla for all Muslims at Ghadiri Khum Oasis just a few months before his death, the people that came to look upon Ali as Muhammad's immediate successor even before Muhamamd's death came to be known as the Shia. However, for the Sunnis the word simply means the 'beloved' or the 'revered' and has no other significance at all.

By the verse Quran, 2:124, Shias believe that Imamah is a divine position always Imamah is accompanied by the word guidance, of course a guidance by God's Command.A kind of guidance which brings humanity to the goal. Regarding 17:71, no age can be without an Imam. So, according to the upper verse 1.Imamah is a position which is appointed by God and must be specified by Him 2.Imam is protected by a divine protection and no one exceles him in nobility 3. No age can be without an Imam and finally Imam knows everything which is needed for human being to get to the truth and goal.

According to the majority of Shī'a, namely the Twelvers (Ithnā'ashariyya), the following is a listing of the rightful successors to Muḥammad. Each Imam was the son of the previous Imam except for Hussayn ibn 'Alī, who was the brother of Hassan ibn 'Alī.The belief in this succession to Muḥammad stems from various Quranic verses which include: 75:36, 13:7, 35:24, 2:30, 2:124, 36:26, 7:142, 42:23.[citation needed] They support their discussion by citing Genesis 17:19–20 and Sunni hadith:Sahih Muslim, Hadith number 4478, English translation by Abdul Hamid Siddiqui.[original research?]

Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower.

What type of sensation is pitch?

auditory

What is pitch closely related to?

frequency

Each persons perception of sound is called?

Pitch


This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69. (See Frequencies of notes.) Distance in this space corresponds to musical intervals as understood by musicians. An equal-tempered semitone is subdivided into 100 cents. The system is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C♯ (61) can be labeled 60.5.

Octaves in linear pitch are what size?

Semitones in linear pitch are what size?

The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems. In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is 880 Hz (info).

What is the most common method of organization?

twelve-note chromatic scale

The pitch ratio between any two successive notes is?

the twelfth root of two

All these different methods have what in common?

the octave


According to the American National Standards Institute, pitch is the auditory attribute of sound according to which sounds can be ordered on a scale from low to high. Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation. Despite that, the idiom relating vertical height to sound pitch is shared by most languages. At least in English, it is just one of many deep conceptual metaphors that involve up/down. The exact etymological history of the musical sense of high and low pitch is still unclear. There is evidence that humans do actually perceive that the source of a sound is slightly higher or lower in vertical space when the sound frequency is increased or decreased.

Pitch is the auditory attribute to what?

sound

Pitch is a close proxy for what?

frequency

High pitch is what type of oscillation?

rapid

Low pitch is what type of oscillation?

slower


A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once. The vibration with the lowest frequency is called the fundamental frequency; the other frequencies are overtones. Harmonics are an important class of overtones with frequencies that are integer multiples of the fundamental. Whether or not the higher frequencies are integer multiples, they are collectively called the partials, referring to the different parts that make up the total spectrum.

This produces many modes of vibration that occur simultaneously?

sound generated

A listener can hear how many frequencies at once?

numerous

Harmonics are an important class of what?

overtones

Integer multiples are collectively called?

the partials


The pitch of complex tones can be ambiguous, meaning that two or more different pitches can be perceived, depending upon the observer. When the actual fundamental frequency can be precisely determined through physical measurement, it may differ from the perceived pitch because of overtones, also known as upper partials, harmonic or otherwise. A complex tone composed of two sine waves of 1000 and 1200 Hz may sometimes be heard as up to three pitches: two spectral pitches at 1000 and 1200 Hz, derived from the physical frequencies of the pure tones, and the combination tone at 200 Hz, corresponding to the repetition rate of the waveform. In a situation like this, the percept at 200 Hz is commonly referred to as the missing fundamental, which is often the greatest common divisor of the frequencies present.

The pitch of complex tones can be?

ambiguous

A complex tone is composed of how many waves?

two

The percept at 200 Hz is commonly referred to as?

the missing fundamental

the percept at 200 Hz is commonly referred to as the missing fundamental, which is often?

divisor of the frequencies present


The just-noticeable difference (jnd) (the threshold at which a change is perceived) depends on the tone's frequency content. Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if the two tones are played simultaneously as the listener is then able to discern beat frequencies. The total number of perceptible pitch steps in the range of human hearing is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120.

The just-noticeable difference, at which a change is perceived depends on what?

the tone's frequency content

The jnd is typically tested by?

playing two tones in quick succession

What is the range of perceptible pitch steps to human hearing?


It is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another. For instance, a snare drum sounds higher pitched than a bass drum though both have indefinite pitch, because its sound contains higher frequencies. In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but sounds of indefinite pitch do not neatly correspond to any specific pitch. A special type of pitch often occurs in free nature when sound reaches the ear of an observer directly from the source, and also after reflecting off a sound-reflecting surface. This phenomenon is called repetition pitch, because the addition of a true repetition of the original sound to itself is the basic prerequisite.

Which drum has a higher perceived pitch even though they both have indefinite pitch?

snare drum

Repetition pitch is caused by what phenomenon?

the addition of a true repetition of the original sound

It is possible and often easy to roughly discern the relative pitches of two sounds of what?

indefinite pitch


For example, one might refer to the A above middle C as a', A4, or 440 Hz. In standard Western equal temperament, the notion of pitch is insensitive to "spelling": the description "G4 double sharp" refers to the same pitch as A4; in other temperaments, these may be distinct pitches. Human perception of musical intervals is approximately logarithmic with respect to fundamental frequency: the perceived interval between the pitches "A220" and "A440" is the same as the perceived interval between the pitches A440 and A880. Motivated by this logarithmic perception, music theorists sometimes represent pitches using a numerical scale based on the logarithm of fundamental frequency. For example, one can adopt the widely used MIDI standard to map fundamental frequency, f, to a real number, p, as follows

The notion of pitch is insensitive to what?

spelling

The description "G4 double sharp" refers to the same pitch as what?
