Giant Steps is a landmark composition by John Coltrane, first recorded in 1959 and released on the album of the same name on Atlantic Records in 1960. The piece is built on what became known as Coltrane changes, a harmonic system that cycles through three tonal centers separated by major thirds, creating rapid modulations that demand extraordinary technical facility from improvisers. The tune required two recording sessions two months apart before Coltrane approved the final take, and the blazing tempo tested even the elite musicians in the studio, including pianist Tommy Flanagan, whose hesitant solo became one of the most discussed moments in jazz history. Within Coltrane's body of work, Giant Steps represents the culmination of his sheets of sound era, connecting to related compositions like Countdown and Central Park West that explore similar intervallic relationships. The composition has become one of the most important test pieces in jazz, a rite of passage for aspiring improvisers and a staple of jazz education. Its compact sixteen-bar form packs an extraordinary density of harmonic motion into a brief cycle, making each chorus a demanding sprint through shifting key centers. The AllSolos database features the iconic 1959 recording with Coltrane on tenor saxophone alongside Tommy Flanagan on piano, as well as a 2021 tribute performance by the Chad LB Quartet with Chad Lefkowitz-Brown on tenor saxophone and Steven Feifke on piano.
