Soul Jazz came partly from the funky subcategory of hard bop. Its earthy, bluesy melodic concept and the repetitive, dance-like rhythmic aspects stood as higher priorities than the invention of complex harmonies and intricate solo improvisations jazz swing feeling was foremost. Considerably simplified-often only a hint of bebop harmony or rhythmic complexity remained--soul-jazz became the form of hard bop known to the largest audience, particularly in the music of Jimmy Smith, Shirley Scott, Jack McDuff, Richard "Groove" Holmes, Jimmy McGriff, Ramsey Lewis, Les McCann, Hank Crawford, Stanley Turrentine and Houston Person. Soul Jazz combined the urban, electrified Chicago harp style with that of California swing bands and added a touch of Philadelphia tenor sax jazz from the 1960s.
