"All of You" is a popular song composed by Cole Porter for the Broadway musical Silk Stockings, which premiered in 1955. The song was introduced on stage by Don Ameche and later performed by Fred Astaire in the 1957 film adaptation. Porter's melody is built on a distinctive rhythmic motif of a dotted half note followed by a quarter note, spanning a wide range from low to high registers while remaining lyrical and singable. The harmony is notably rich and chromatic, featuring a recurring minor IV chord that lends the piece an unexpected sophistication uncommon in popular songs of the era. The chord movement walks down by half steps, creating a sense of harmonic restlessness beneath the surface of an otherwise warm and romantic song. These qualities have made "All of You" particularly attractive to jazz musicians, and it became a widely performed standard in both vocal and instrumental settings. Miles Davis recorded a landmark version on his 1957 album Round About Midnight, featuring solos by John Coltrane and Red Garland, while Ella Fitzgerald included it on her celebrated Cole Porter Song Book. Bill Evans, Ahmad Jamal, the Modern Jazz Quartet, Sarah Vaughan, and Keith Jarrett have all recorded notable interpretations. The composition's inclusion in the Real Book confirms its place as a core piece of the jazz repertoire, representing a mature and harmonically inventive work from Porter's later career.
