Input (English): Context: Los Angeles (Spanish for "The Angels"), officially the City of Los Angeles and often known by its initials L.A., is the second-most populous city in the United States (after New York City), the most populous city in California and the county seat of Los Angeles County. Situated in Southern California, Los Angeles is known for its mediterranean climate, ethnic diversity, sprawling metropolis, and as a major center of the American entertainment industry. Los Angeles lies in a large coastal basin surrounded on three sides by mountains reaching up to and over ., West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. West Africa has been defined as including 18 countries: Benin, Burkina Faso, the island nation of Cape Verde, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, the island of Saint Helena, Senegal, Sierra Leone, São Tomé and Príncipe and Togo., Ragtime  also spelled rag-time or rag time  is a musical genre that enjoyed its peak popularity between 1895 and 1918. Its cardinal trait is its syncopated, or "ragged", rhythm. The genre has its origins in African-American communities like St. Louis years before being published as popular sheet music for piano. Ernest Hogan (18651909) was a pioneer of ragtime music and was the first to compose ragtime into sheet music. The composition was called "LA Pas Ma LA" and it was released in 1895. Hogan has also been credited for coining the term "ragtime". The term is actually derived from his hometown "Shake Rag" in Bowling Green, Kentucky. Ben Harney, who is also a Kentucky native has often been credited for introducing the music to the mainstream public. His first ragtime composition "You've been a good old wagon but you done broke" helped popularize the musical genre. The composition was published in 1895 but released in 1896. Ragtime was also a modification of the march made popular by John Philip Sousa, with additional polyrhythms coming from African music. The ragtime composer Scott Joplin ("ca." 18681917) became famous through the publication of the "Maple Leaf Rag" (1899) and a string of ragtime hits such as "The Entertainer" (1902), although he was later forgotten by all but a small, dedicated community of ragtime aficionados until the major ragtime revival in the early 1970s. For at least 12 years after its publication, "Maple Leaf Rag" heavily influenced subsequent ragtime composers with its melody lines, harmonic progressions or metric patterns., A chord progression or harmonic progression is a succession of musical chords. Chord progressions are the foundation of harmony in Western musical tradition., The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world., Geary Boulevard (designated as Geary Street east of Van Ness Avenue) is a major east-west long thoroughfare in San Francisco, California, United States, beginning downtown at Market Street near Market Street's intersection with Kearny Street, and running westbound through downtown, the Civic Center area, the Western Addition, and running for most of its length through the predominantly residential Richmond District. Geary Boulevard terminates near Sutro Heights Park at 48th Avenue, close to the Cliff House above Ocean Beach at the Pacific Ocean. At 40th Avenue, Geary intersects with Point Lobos Avenue, which takes through traffic to the Cliff House, Ocean Beach and the Great Highway. It is a major commercial artery through the Richmond District; it is lined with stores and restaurants, many of them catering to the various immigrant groups (Chinese, Russian, and Irish, among many others) who live in the area. The boulevard borders Japantown between Fillmore and Laguna Streets., In jazz and blues, a blue note (also "worried" note) is a note thatfor expressive purposesis sung or played at a slightly different pitch than standard. Typically the alteration is between a quartertone and a semitone, but this varies among performers and genres., Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove., Beefy Red was an American , San Francisco Bay Area music band ( 1969 -- 1972 ) based in Marin County , California , United States , which played at various Bay Area venues , including Bill Graham 's Fillmore West from October 22 -- 25 in 1970 . Beefy Red performed frequently at San Anselmo 's ' The Lion 's Share ' , a club often cited as one of the most historic in the history of the Marin County music scene . The group was most noted for playing `` swinging R&B '' but played other syles like blues and jazz . In 2008 Beefy Red was included by Paul Liberatore , of the Marin Independent Journal , on a list of potential nominees for a proposed ' Marin Music Museum ' ., Improvisation is broad term referring to the process of devising an atypical method of solving a problem due to lack of time or resources. In a technical context, this can mean adapting a device for some use other than that which it was designed for, or building a device from unusual components in an ad-hoc fashion. Improvisation, within the context of performing arts, is a very spontaneous performance without specific or scripted preparation. The skills of improvisation can apply to many different faculties, across all artistic, scientific, physical, cognitive, academic, and non-academic disciplines., Polyrhythm is the simultaneous use of two or more conflicting rhythms, that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic conflict may be the basis of an entire piece of music (cross-rhythm), or a momentary disruption. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm., A music venue is any location used for a concert or musical performance. A music venue range in size and location, from an outdoor bandshell or bandstand or a concert hall to an indoor sports stadium. Typically, different types of venues host different genres of music. Opera houses, bandshells, and concert halls host classical music performances, whereas public houses, nightclubs, and discothèques offer music in contemporary genres, such as rock, dance, country and pop., A chant (from French ', from Latin ', "to sing") is the rhythmic speaking or singing of words or sounds, often primarily on one or two main pitches called reciting tones. Chants may range from a simple melody involving a limited set of notes to highly complex musical structures, often including a great deal of repetition of musical subphrases, such as Great Responsories and Offertories of Gregorian chant. Chant may be considered speech, music, or a heightened or stylized form of speech. In the later Middle Ages some religious chant evolved into song (forming one of the roots of later Western music)., The San Francisco Bay Area (referred to locally as the Bay Area) is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the major cities and metropolitan areas of San Jose, San Francisco, and Oakland, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.65 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels and commuter rail. The combined statistical area of the region is the second-largest in California (after the Greater Los Angeles area), the fifth-largest in the United States, and the 43rd-largest urban area in the world., Popular music is music with wide appeal that is typically distributed to large audiences through the music industry. These forms and styles can be enjoyed and performed by people with little or no musical training. It stands in contrast to both art music and traditional or "folk" music. Art music was historically disseminated through the performances of written music, although since the beginning of the recording industry, it is also disseminated through recordings. Traditional music forms such as early blues songs or hymns were passed along orally, or to smaller, local audiences., Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms"., The Jazz Age was a period in the 1920s, ending with the Great Depression, in which jazz music and dance styles became popular, mainly in the United States, but also in Britain, France and elsewhere. Jazz originated in New Orleans as a fusion of African and European music and played a significant part in wider cultural changes in this period, and its influence on pop culture continued long afterwards. The Jazz Age is often referred to in conjunction with the Roaring Twenties., Commuter rail, also called suburban rail, is a passenger rail transport service that primarily operates between a city centre, and the middle to outer suburbs beyond 15 km (10 miles) and commuter towns or other locations that draw large numbers of commuterspeople who travel on a daily basis. Trains operate following a schedule, at speeds varying from 50 to 200 km/h (30 to 125 mph). Distance charges or zone pricing may be used., Van Ness Avenue is a north-south thoroughfare in San Francisco, California, running from Market St north to the Bay. Originally named Marlette Street, the street was renamed Van Ness Avenue in honor of the city's seventh mayor, James Van Ness. Van Ness Avenue begins at Market Street near the Civic Center, and extends north to end at Bay Street at Fort Mason. Of the more striking landmarks along the route are the San Francisco City Hall, the War Memorial Opera House, and Louise M. Davies Symphony Hall., The term musical form (or musical architecture) refers to the overall structure or plan of a piece of music, and it describes the layout of a composition as divided into sections. In the tenth edition of "The Oxford Companion to Music", Percy Scholes defines musical form as "a series of strategies designed to find a successful mean between the opposite extremes of unrelieved repetition and unrelieved alteration.", Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music. "Traditional folk music" has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles., Nevada (Spanish for "snowy"; see pronunciations) is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, and the 9th least densely populated of the 50 United States. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las VegasParadise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital is Carson City. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State", because it achieved statehood during the Civil War (the words "Battle Born" also appear on the state flag); as the "Sage-brush State", for the native plant of the same name; and as the "Sage-hen State". Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east., Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition., Arizona (O'odham: "Al onak" [ai onak]) is a state in the southwestern region of the United States. It is also part of the Western United States and the Mountain West states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is one of the Four Corners states. It has borders with New Mexico, Utah, Nevada, California, and Mexico, and one point in common with the southwestern corner of Colorado. Arizona's border with Mexico is 389 miles (626 km) long, on the northern border of the Mexican states of Sonora and Baja California., California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City. The state also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County., The Deep South is a cultural and geographic subregion in the Southern United States. Historically, it is differentiated from the "Upper South" as being the states most dependent on plantation-type agriculture and considered slave societies during the preCivil War period. The Deep South was also commonly referred to as the Lower South or the Cotton States, for their production of cotton as the primary commodity crop., Fillmore West was a historic rock and roll music venue in San Francisco, California which became famous under the direction of concert promoter Bill Graham from 1968-1971. Named after Graham's original "Fillmore" location at the intersection of Fillmore Street and Geary Boulevard, it stood at the southwest corner of Market Street and South Van Ness Avenue. There is now a Honda automobile dealership at that location., Honda has been the world's largest motorcycle manufacturer since 1959, as well as the world's largest manufacturer of internal combustion engines measured by volume, producing more than 14 million internal combustion engines each year. Honda became the second-largest Japanese automobile manufacturer in 2001. Honda was the eighth largest automobile manufacturer in the world behind General Motors, Volkswagen Group, Toyota, Hyundai Motor Group, Ford, Nissan, and PSA Peugeot Citroën in 2011., Rhythm and blues, often abbreviated as R&B or RnB, is a genre of popular African-American music that originated in the 1940s. The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when "urbane, rocking, jazz based music with a heavy, insistent beat" was becoming more popular.
In the commercial rhythm and blues music typical of the 1950s through the 1970s, the bands usually consisted of piano, one or two guitars, bass, drums, saxophone, and sometimes background vocalists. R&B lyrical themes often encapsulate the African-American experience of pain and the quest for freedom and joy. Lyrics focus heavily on the themes of triumphs and failures in terms of relationships, freedom, economics, aspirations, and sex., The 12-bar blues or "blues changes" is one of the most prominent chord progressions in popular music. The blues progression has a distinctive form in lyrics, phrase, chord structure, and duration. In its basic form, it is predominantly based on the I-IV-V chords of a key., A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its "Category II" type of protected areas., Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northernmost and westernmost of the 31 states which, with Mexico City, comprises the 32 Federal Entities of Mexico. Before becoming a state in 1953, the area was known as the North Territory of Baja California ("El Territorio Norte de Baja California"). It has an area of , or 3.57% of the land mass of Mexico and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean, on the east by Sonora, the U.S. State of Arizona, and the Gulf of California (also known as the "Sea of Cortez"), and on the south by Baja California Sur. Its northern limit is the U.S. state of California., The term blues scale refers to several different scales with differing numbers of pitches and related characteristics., The field holler or field call is a mostly historical type of vocal music sung by southern labourers to accompany their work, to communicate usefully or to vent feelings. It differs from the collective work song in that it was sung solo, though early observers noted that a holler, or cry, might be echoed by other workers. Though commonly associated with cotton cultivation, the field holler was also sung by levee workers, and field hands in rice and sugar plantations. Field hollers are also known as corn-field hollers, water calls, and whoops. An early description is from 1853 and the first recordings are from the 1930s. The holler is closely related to the call and response of work songs, and arhoolies, to Afro-American and ultimately influenced strands of African American music, such as the blues, rhythm and blues, and spirituals., Rock and roll (often written as rock & roll or rock 'n' roll) is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s, from African-American musical styles such as gospel, jazz, boogie woogie, and rhythm and blues, with country. While elements of rock and roll can be heard in blues records from the 1920s and in country records of the 1930s, the genre did not acquire its name until the 1950s., A work song is a piece of music closely connected to a form of work, either sung while conducting a task (usually to coordinate timing) or a song linked to a task which might be a connected narrative, description, or protest song., A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions. It is to be distinguished from "musical form" and "musical style", although in practice these terms are sometimes used interchangeably. Recently, academics have argued that categorizing music by genre is inaccurate and outdated., African-American music is an umbrella term covering a diverse range of musics and musical genres largely developed by African Americans. Their origins are in musical forms that arose out of the historical condition of slavery that characterized the lives of African Americans prior to the American Civil War., Subject: beefy red, Relation: genre, Options: (A) agriculture (B) art (C) automobile (D) blues (E) concert (F) country (G) dance (H) economics (I) economy (J) education (K) entertainment (L) fashion (M) folk music (N) genre (O) gregorian chant (P) history (Q) james (R) japanese (S) jazz (T) march (U) mass (V) military band (W) music (X) musical (Y) nature (Z) protest song ([) ragtime (\) rhythm and blues (]) rock (^) rock and roll (_) song (`) symphony (a) travel (b) urban (c) various (d) war (e) western (f) world music
