Erroll Louis Garner (June 15, 1921 – January 2, 1977) was an American jazz pianist and composer whose distinctive and melodic style brought him both popular acclaim and the admiration of peers. Of note, Garner was never able to read or write sheet music.

What makes Garner's playing easy to recognize is his trademark introductions, which seem to make no sense until breaking dramatically into his exposition of the tune he will play, and the guitar strumming sound of his left hand, playing crotchet accompaniment to his rich sounding right hand. He places his chords and octaves on syncopated beats that swing very hard and can be used to build excellent tension, such as between phrases. The approach also suggests he was influenced by the iconic rhythm guitar work of Count Basie's long time guitarist, Freddie Green. But discerning listeners could find that while his even four left hand was a fixture, it was far from being the only rhythmic approach he took to playing.
