From its early development until the present, jazz has also incorporated music from 19th and 20th century American popular music, which is based on European music traditions.[2] 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; for the origin and history, see Jazz (word).
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 later developments such as acid jazz.
