Oliver performed mostly on cornet, but like many cornetists he switched to trumpet in the late 1920s. He credited jazz pioneer Buddy Bolden as an early influence, and in turn was a major influence on numerous younger cornet/trumpet players in New Orleans and Chicago, including Tommy Ladnier, Paul Mares, Muggsy Spanier, Johnny Wiggs, Frank Guarente and, the most famous of all, Armstrong. One of his protégés, Louis Panico (cornetist with the Isham Jones Orchestra), authored a book entitled "The Novelty Cornetist", which is illustrated with photos showing some of the mute techniques he learned from Oliver.
