Well You Needn't is a jazz standard written by Thelonious Monk in 1944 for his singer-student Charlie Beamon, who replied “Well You Needn’t” when Monk said he’d name the tune after him. The piece uses chromatically moving dominant chords, giving it a distinctive, sly swing. There are two known bridge changes: Monk’s original progression and the Miles Davis version that has become widely played in jam sessions. Miles Davis’s version is particularly popular in practice rooms and is often learned from the Real Book. The tune is a staple of the jazz repertoire, with chord charts available for multiple instruments, and the album listing is not provided in the given content.
