When did John Coltrane add the soprano saxophone to his list of jazz instruments?
1960. From Wikipedia: His first record with his new group was also his debut playing the soprano saxophone, the hugely successful ‘My Favorite Things’. Around the end of his tenure with Davis, Coltrane had begun playing soprano saxophone, an unconventional move considering the instrument’s near obsolescence in jazz at the time. His interest in the straight saxophone most likely arose from his admiration for Sidney Bechet and the work of his contemporary, Steve Lacy, even though Miles Davis claimed to have given Coltrane his first soprano saxophone. The new soprano sound was coupled with further exploration. For example, on the Gershwin tune “But Not for Me”, Coltrane employs the kinds of restless harmonic movement (Coltrane changes) used on Giant Steps (movement in major thirds rather than conventional perfect fourths) over the A sections instead of a conventional turnaround progression.
