context_page_description: The music of the United States reflects the country's pluri-ethnic population through a diverse array of styles. It is a mixture of music influenced by music of the United Kingdom, West African, Irish, Latin American, and mainland European cultures among others. The country's most internationally renowned genres are jazz, blues, country, bluegrass, rock, rock and roll, R&B, soul, gospel, ragtime, funk, hip hop, doo wop, pop, techno, house, folk music, americana, disco, boogaloo, reggaeton, and salsa. American music is heard around the world. Since the beginning of the 20th century, some forms of American popular music have gained a near-global audience.
  Native Americans were the earliest inhabitants of the land that is today known as the United States and played its first music. Beginning in the 17th century, immigrants from the United Kingdom, Ireland, Spain, Germany, and France began arriving in large numbers, bringing with them new styles and instruments. African slaves brought their own musical traditions, and each subsequent wave of immigrants contributed to a melting pot.
context_section_description: Jazz is a kind of music characterized by swung and blue notes, call and response vocals, polyrhythms and improvisation. Though originally a kind of dance music, jazz has been a major part of popular music, and has also become a major element of Western classical music. 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. Early jazz was closely related to ragtime, with which it could be distinguished by the use of more intricate rhythmic improvisation. The earliest jazz bands adopted much of the vocabulary of the blues, including bent and blue notes and instrumental "growls" and smears otherwise not used on European instruments. Jazz's roots come from the city of New Orleans, Louisiana, populated by Cajuns and black Creoles, who combined the French-Canadian culture of the Cajuns with their own styles of music in the 19th century. Large Creole bands that played for funerals and parades became a major basis for early jazz, which spread from New Orleans to Chicago and other northern urban centers.
  Though jazz had long since achieved some limited popularity, it was Louis Armstrong who became one of the first popular stars and a major force in the development of jazz, along with his friend pianist Earl Hines. Armstrong, Hines, and their colleagues were improvisers, capable of creating numerous variations on a single melody. Armstrong also popularized scat singing, an improvisational vocal technique in which nonsensical syllables (vocables) are sung. Armstrong and Hines were influential in the rise of a kind of pop big band jazz called swing. Swing is characterized by a strong rhythm section, usually consisting of double bass and drums, medium to fast tempo, and rhythmic devices like the swung note, which is common to most jazz. Swing is primarily a fusion of 1930s jazz fused with elements of the blues and Tin Pan Alley. Swing used bigger bands than other kinds of jazz, leading to bandleaders tightly arranging the material which discouraged improvisation, previously an integral part of jazz. Swing became a major part of African American dance, and came to be accompanied by a popular dance called the swing dance.
  Jazz influenced many performers of all the major styles of later popular music, though jazz itself never again became such a major part of American popular music as during the swing era. The later 20th-century American jazz scene did, however, produce some popular crossover stars, such as Miles Davis. In the middle of the 20th century, jazz evolved into a variety of subgenres, beginning with bebop. Bebop is a form of jazz characterized by fast tempos, improvisation based on harmonic structure rather than melody, and use of the flatted fifth. Bebop was developed in the early and mid-1940s, later evolving into styles like hard bop and free jazz. Innovators of the style included Charlie Parker and Dizzy Gillespie, who arose from small jazz clubs in New York City.
