This family is the jazz-club core: horn-led heads, dense harmony, walking bass, ride cymbal time, fast lines, blues feeling, and the primacy of improvisation.
History
Bebop broke away from dance-band priorities in Harlem jam sessions, hard bop re-grounded it in blues and gospel, and straight-ahead/mainstream practice kept the acoustic modern-jazz center alive against fusion and free-jazz competition. Most of what many listeners casually mean by “jazz combo” lives somewhere in this family.
