Funk originated in the mid-1960s, with James Brown's development of a signature groove that emphasized the downbeat—with heavy emphasis on the first beat of every measure ("The One"), and the application of swung 16th notes and syncopation on all basslines, drum patterns, and guitar riffs—and rock and psychedelia-influenced musicians Sly and the Family Stone and Jimi Hendrix, fostering improvisation in funk. Other musical groups, including Kool and the Gang, B.T. Express, Fatback Band, Slave, Cameo, Con Funk Shun, the Bar-Kays, and Ohio Players, began to adopt and develop Brown's innovations during the 1970s while others like Parliament-Funkadelic followed Hendrix's path.
