Metamorphosis is a hard bop composition by pianist and composer Horace Silver, written for his quintet and first recorded on May 8, 1957, at Rudy Van Gelder Studio in Hackensack, New Jersey, for the Blue Note album The Stylings of Silver. The original session featured Art Farmer on trumpet, Hank Mobley on tenor saxophone, Teddy Kotick on bass, and Louis Hayes on drums, with Alfred Lion producing. The tune follows an AAB form over an expansive 80-bar structure, making it one of the more extended compositions on the album and allowing considerable room for melodic development within its written sections. The piece features Silver's signature blend of lyrical melody and blues-inflected harmony, with a mid-tempo swinging groove that includes a shout chorus emphasizing rhythmic accents caught by piano and drums while the bass walks in four. It is not a contrafact but a fully original composition. Metamorphosis sits within Silver's prolific 1950s output at Blue Note, a period that produced some of hard bop's defining recordings. The tune shares the album with other Silver originals including No Smokin', Soulville, and Home Cookin', all recorded at the same session. While it has not been widely adopted as a jazz standard and remains primarily associated with the original recording and subsequent Silver reissues, the composition demonstrates Silver's range as a writer capable of working in extended forms while maintaining the soulful, funky sensibility that defined his contribution to the hard bop idiom.
