Lady Bird is a sixteen-bar bebop jazz standard composed by Tadd Dameron around 1939 and first released in 1948. The tune features a suave, mellow theme and is known as the origin of the Tadd Dameron turnaround. It is written in binary form (AABC) and uses ii-V turnarounds that briefly move to Eb, Ab, and G before resolving back to C. The piece has been widely recorded by many great players and appears on numerous albums, with no single original album attached to it. The harmonic language influenced Miles Davis, whose Half Nelson uses a nearly identical chord progression, and the track has been performed by Art Blakey, Stan Getz, Dexter Gordon, Chet Baker, Gerry Mulligan and many others. Lyrics were later added by Stanley Cornfield, with the opening line We fit together like two birds of a feather.
