Other trends
There was a resurgence of interest in jazz and other forms of African American cultural expression during the Black Arts Movement and Black nationalist period of the early 1970s. Musicians such as Pharoah Sanders, Hubert Laws and Wayne Shorter began using African instruments such as kalimbas, cowbells, beaded gourds and other instruments not traditional to jazz. Musicians began improvising jazz tunes on unusual instruments, such as the jazz harp (Alice Coltrane), electrically-amplified and wah-wah pedaled jazz violin (Jean-Luc Ponty), and even bagpipes (Rufus Harley). Jazz continued to expand and change, influenced by other types of music, such as world music, avant garde classical music, and rock and pop music. Guitarist John McLaughlin's Mahavishnu Orchestra played a mix of rock and jazz infused with East Indian influences. The ECM record label began in Germany in the 1970s with artists including Keith Jarrett, Paul Bley, the Pat Metheny Group, Jan Garbarek, Ralph Towner, Kenny Wheeler, John Taylor, John Surmand Eberhard Weber, establishing a new chamber music aesthetic, featuring mainly acoustic instruments, and sometimes incorporating elements of world music and folk music.

Jazz fusion
In the late 1960s and early 1970s the hybrid form of jazz-rock fusion was developed by combining jazz improvisation with rock rhythms, electric instruments, and the highly amplified stage sound of rock musicians such as Jimi Hendrix. Miles Davis made the breakthrough into fusion in 1970s with his album Bitches Brew, and by 1971, two influential fusion groups formed: Weather Report and the Mahavishnu Orchestra. Although jazz purists protested the blend of jazz and rock, some of jazz's significant innovators crossed over from the contemporary hard bop scene into fusion. Jazz fusion music often uses mixed meters, odd time signatures, syncopation, and complex chords and harmonies. In addition to using the electric instruments of rock, such as the electric guitar, electric bass, electric piano, and synthesizer keyboards, fusion also used the powerful amplification, "fuzz" pedals, wah-wah pedals, and other effects used by 1970s-era rock bands. Notable performers of jazz fusion included Miles Davis, keyboardists Joe Zawinul, Chick Corea, Hiromi Uehara, Herbie Hancock, vibraphonist Gary Burton, drummer Tony Williams, guitarists Larry Coryell and John McLaughlin, Frank Zappa, saxophonist Wayne Shorter, and bassists Jaco Pastorius and Stanley Clarke.

Soul jazz

Soul jazz was a development of hard bop which incorporated strong influences from blues, gospel and rhythm and blues in music for small groups, often the organ trio which partnered a Hammond organ player with a drummer and a tenor saxophonist. Unlike hard bop, soul jazz generally emphasized repetitive grooves and melodic hooks, and improvisations were often less complex than in other jazz styles. Horace Silver had a large influence on the soul jazz style, with his songs that used funky and often gospel-based piano vamps. Important soul jazz organists included Jimmy McGriff and Jimmy Smith and Johnny Hammond Smith, and influential tenor saxophone players included Eddie "Lockjaw" Davis and Stanley Turrentine.

Jazz Music in 1960-70s

Latin jazz
Latin jazz combines rhythms from African and Latin American countries, often played on instruments such as conga, timbale, güiro, and claves with jazz and classical harmonies played on typical jazz instruments (piano, double bass, etc.). There are two main varieties: Afro-Cuban jazz was played in the US directly after the bebop period, while Brazilian jazz became more popular in the 1960s. Afro-Cuban jazz began as a movement in the mid-1950s as bebop musicians such as Dizzy Gillespie and Billy Taylor started Afro-Cuban bands influenced by such Cuban and Puerto Rican musicians as Xavier Cugat, Tito Puente, and Arturo Sandoval. Brazilian jazz such as bossa nova is derived from samb, with influences from jazz and other 20th century classical and popular music styles. Bossa is generally moderately paced, with melodies sung in Portuguese or English. The style was pioneered by Brazilians João Gilberto and Antônio Carlos Jobim. The related term jazz-samba describes an adaptation of bossa nova compositions to the jazz idiom by American performers such as Stan Getz and Charlie Byrd.

About Jazz

Jazz is a primarily American musical art form which originated at the beginning of the 20th century in African American communities in the Southern United States from a confluence of African and European music traditions.
The word jazz began as a West Coast slang term of uncertain derivation and was first used to refer to music in Chicago in about 1915.
Jazz has, from its early 20th century inception, spawned a variety of subgenres, from New Orleans Dixieland dating from the early 1910s, big band-style swing from the 1930s and 1940s, bebop from the mid-1940s, a variety of Latin jazz fusions such as Afro-Cuban and Brazilian jazz from the 1950s and 1960s, jazz-rock fusion from the 1970s and late 1980s developments such as acid jazz, which blended jazz influences into funk and hip-hop. As the music has spread around the world it has drawn on local national and regional musical cultures, its aesthetics being adapted to its varied environments and giving rise to many distinctive styles.
