Mongo Santamaria recorded his composition "Afro Blue" in 1959 when playing with the Cal Tjader Sextet.[1] "Afro Blue" was the first jazz standard built on a typical African 3:2 cross-rhythm, or hemiola.Since the main beats are grouped as four sets of three pulses (dotted quarter-notes in the top example), the bell pattern significantly contradicts the meter.Coltrane and Jones reversed the metric hierarchy of Santamaria's composition, by performing in 34 swing (2:3), instead of 68 or 128 (3:2).Roberta Flack's vocal recording of "Afro Blue" (on the 2020 reissue of 1969's First Take) uses Coltrane's arrangement.
