Thomas "Fats" Waller (1904-1943) was a pianist, organist, and composer who shaped the sound of jazz and popular music in the 1920s and 1930s. His technical mastery at the keyboard combined with an irrepressible sense of humor made him one of the era's most recorded and celebrated musicians. Waller composed prolifically for stage and film, leaving behind standards that remain central to the jazz and theater repertoire.
As both performer and bandleader, Waller demonstrated how swing rhythm and harmonic sophistication could coexist with accessibility and joy. His approach to the keyboard influenced generations of jazz pianists and continues to inform how musicians think about comping, voicing, and rhythmic feel.
