How High the Moon was composed by Morgan Lewis with lyrics by Nancy Hamilton for the 1940 Broadway revue Two for the Show. Originally conceived as a romantic ballad, the song features a soaring melody over a harmonically rich chord progression that moves through unexpected key areas, making it irresistible to jazz improvisers. Benny Goodman and His Orchestra with vocalist Helen Forrest recorded the first hit version in February 1940, and the song quickly entered the jazz mainstream. Its chord changes proved so fertile for improvisation that they became one of the most frequently borrowed harmonic frameworks in bebop and post-bop jazz, serving as the foundation for Charlie Parker's Ornithology, John Coltrane's Satellite, and other well-known contrafacts. Ella Fitzgerald's 1947 performance, in which she scatted freely over the changes and quoted Ornithology, helped cement the tune's place in the jazz vocabulary. Les Paul and Mary Ford's innovative multi-tracked recording topped the Billboard charts for nine weeks in 1951, demonstrating the song's appeal across genres. How High the Moon remains one of the essential jazz standards, performed in settings ranging from intimate duo to big band and studied by musicians for its elegantly constructed harmonic movement.
