リズム・アンド・ブルース
Tresillo, the habanera, and related African-based single-celled figures have long been heard in the left hand-part of piano compositions by New Orleans musicians, such as Louis Moreau Gottschalk ("Souvenirs from Havana", 1859) and Jelly Roll Morton ("The Crave", 1910). One of Longhair's great contributions was the adaptation of Afro-Cuban two-celled, clave-based patterns in New Orleans blues. Michael Campbell stated, "Rhythm and blues influenced by Afro-Cuban music first surfaced in New Orleans. Professor Longhair's influence was ... far reaching. In several of his early recordings, Professor Longhair blended Afro-Cuban rhythms with rhythm and blues. The most explicit is 'Longhair's Blues Rhumba,' where he overlays a straightforward blues with a clave rhythm." The guajeo-like piano part for the rumba-boogie "Mardi Gras in New Orleans" (1949) employs the 2-3 clave onbeat/offbeat motif. The 2-3 clave time line is written above the piano excerpt for reference.
