Giant Steps is the fifth studio album by jazz musician John Coltrane as leader. It was released in February 1960 on Atlantic Records. This was his first album as leader for Atlantic Records, with which he had signed a new contract the previous year. The record is regarded as one of the most influential jazz albums of all time. Many of its tracks have become practice templates for jazz saxophonists. In 2004, it was one of fifty recordings chosen that year by the Library of Congress to be added to the National Recording Registry. It attained gold record status in 2018, having sold 500,000 copies. Two tracks, "Naima" and "Syeeda's Song Flute", are respectively named after Coltrane's wife at the time and her daughter, whom he adopted. A third, "Mr. P.C.", takes its name from the initials of bassist Paul Chambers, who played on the album. A fourth, "Cousin Mary", is named in honor of Mary Lyerly, Coltrane's younger cousin. Background In 1959, Miles Davis's business manager Harold Lovett negotiated a record contract for Coltrane with Atlantic, the terms of which included a $7,000 annual guarantee (). Initial sessions for this album, the second recording date for Coltrane under his new contract after a January 15 date led by Milt Jackson, took place on March 26, 1959. Coltrane was dissatisfied with the results of this session with Cedar Walton and Lex Humphries, and hence they were not used for the album, but appeared on subsequent compilations and reissues. Principal recording for the album took place on May 4 and 5, two weeks after Coltrane had participated in the final session for Kind of Blue. The track "Naima" was recorded on December 2 with Coltrane's bandmates, the rhythm section from the Miles Davis Quintet, who would provide the backing for most of his next album, Coltrane Jazz. Coltrane's improvisation exemplifies the melodic phrasing that came to be known as sheets of sound, and features his explorations into third-related chord movements that came to be known as Coltrane changes. The Giant Steps chord progression consists of a distinctive set of chords that create key centers a major third apart. Jazz musicians ever since have used it as a practice piece, its difficult chord changes presenting a "kind of ultimate harmonic challenge", and serving as a gateway into modern jazz improvisation. Several pieces on this album went on to become jazz standards, most
