supports: A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet). Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds and percussion instruments, or the concert band, which uses brass, woodwinds and percussion.  A horn section is a group of musicians playing horns. In an orchestra or concert band, it refers to the musicians who play the "French" horn, and in a British-style brass band it is the tenor horn players. In many popular-music genres the term is applied loosely to any group of woodwind or brass instruments, or a combination of woodwinds and brass.

A jazz band (jazz ensemble or jazz combo) is a musical ensemble that plays jazz music. Jazz bands vary in the quantity of its members and the style of jazz that they play but it is common to find a jazz band made up of a rhythm section and a horn section. A rhythm section (also called a backup band) is a group of musicians within a music ensemble or band who provide the underlying rhythm and pulse of the accompaniment, providing a rhythmic reference and "beat" for the rest of the band. Many of the rhythm section instruments, such as keyboard instruments and guitars, are also used to play the chord progression upon which the song is based. The bass instrument (either double bass or electric bass, or another low-register instrument, such as synth bass, depending on the group and its style of music) plays the low-pitched bassline that supports the chord progression, typically by emphasizing the roots of the chords (and to a lesser degree the fifths and thirds of the chords). 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".
