Thomas "Fats" Waller (1904-1943) was a pianist, organist, and composer who became one of jazz's most influential figures. His harmonic sophistication and stride piano technique set the standard for a generation of players, while his wit and showmanship made him a beloved entertainer on both stage and screen.
Waller's compositions, including "Ain't Misbehavin'" and "Honeysuckle Rose," remain standards in the jazz repertoire. His conception of "When It's Sleepy Time Down South" showcases his gift for reharmonization and his ability to reimagine familiar melodies with fresh harmonic and rhythmic ideas.
