Largely self-taught, by age fifteen, Carter was already sitting in at Harlem night spots. From 1924 to 1928, Carter gained valuable professional experience as a sideman in some of New York's top bands. As a youth, Carter lived in Harlem around the corner from Bubber Miley who was Duke Ellington's star trumpeter, Carter was inspired by Miley and bought a trumpet, but when he found he couldn't play like Miley he traded the trumpet in for a saxophone. For the next two years he played with such jazz greats as cornetist Rex Stewart, clarinetist-soprano saxophonist Sidney Bechet, pianists Earl Hines, Willie "The Lion" Smith, pianist Fats Waller, pianist James P. Johnson, pianist Duke Ellington and their various groups.
