Soul jazz or funky jazz is a subgenre of jazz that incorporates strong influences from hard bop, blues, soul, gospel and rhythm and blues. Soul jazz is often characterized by organ trios featuring the Hammond organ and small combos including saxophone, brass instruments, electric guitar, bass, drums, piano, vocals and electric organ. Its origins were in the 1950s and early 1960s, with its heyday with popular audiences preceding the rise of jazz fusion in the late 1960s and 1970s. Prominent names in fusion ranged from bop pianists including Bobby Timmons and Junior Mance to a wide range of organists, saxophonists, pianists, drummers and electric guitarists including Jack McDuff, Eddie "Lockjaw" Davis, and Grant Green.

Hard bop is a subgenre of jazz that is an extension of bebop music. Journalists and record companies began using the term in the mid-1950s to describe a new current within jazz that incorporated influences from rhythm and blues, gospel music, and blues, especially in saxophone and piano playing.
