Fats Waller (1904-1943) was a pianist, organist, composer, and vocalist whose infectious energy and harmonic sophistication shaped American jazz and popular music. His stride piano technique and gift for comedic vocal delivery made him one of the most recorded artists of the 1930s, while his compositions like 'Honeysuckle Rose' and 'Ain't Misbehavin'' remain standards in the jazz repertoire.
Waller's music bridges concert and vernacular traditions, making him particularly valuable in educational settings where students encounter authentic jazz language and swing idioms. His melodic sense is direct and memorable, yet his harmonic choices reveal a trained musician with deep knowledge of classical music fundamentals.
