Thomas "Fats" Waller (1904–1943) was a pianist, organist, and composer who shaped early jazz and popular song. His technical brilliance at the keyboard matched his gift for melody and harmony; he could voice chords with sophistication while keeping the bounce and swing that made his records so infectious. Waller wrote dozens of standards that remain central to the jazz repertoire, and his recordings reveal a musician equally comfortable with stride piano technique and sophisticated arranging.
Waller's influence on music education extends beyond jazz tradition. His compositions teach voice leading, jazz harmony, and the interplay between melody and accompaniment. Teachers use his work to show students how playfulness and technical command can coexist in serious musicianship.
