Ferdinand "Jelly Roll" Morton (September 20, 1885 ? July 10, 1941) was an American ragtime and early jazz pianist, bandleader and composer.
Widely recognized as a pivotal figure in early jazz, Morton claimed, in self-promotional hyperbole, to have invented jazz outright in 1902. Morton was the first serious composer of jazz, naming and popularizing the "Spanish tinge" of exotic rhythms and penning such standards as "Wolverine Blues", "Black Bottom Stomp", and "Buddy Bolden's Blues".
Morton's piano style was formed from early secondary ragtime and "shout," which also evolved separately into the New York school of stride piano. Morton's playing, however, was also close to barrelhouse, which produced boogie woogie.
Morton often played the melody of a tune with his right thumb, while sounding a harmony above these notes with other fingers of the right hand. This added a rustic or 'out-of-tune' sound (due to the playing of a diminished 5th above the melody). This may still be recognized as belonging to New Orleans. Morton also walked in major and minor sixths in the bass, instead of tenths or octaves. He played basic swing rhythms in both the left and right hand.
