Chameleon (composition)

"Chameleon" is a jazz fusion standard composed by Herbie Hancock with Bennie Maupin, Paul Jackson and Harvey Mason, all of whom also performed the original 15:44 full-length version on the 1973 album Head Hunters, and featuring solos by Hancock and Maupin. The 9:41 edit omits an out-of-tune segment, features a new bassline added in at around 6:40 and new instruments added in post-production.

Background
The song has a characteristic bass line and is set to a funk beat. For the most part, it is built entirely on a two-chord vamp: a i-IV in B♭ Dorian (B♭m7 and E♭7). The piece's signature 12-note bass line was played by Hancock on an ARP Odyssey, as was one of the keyboard solos. The other keyboard solo was played on a Rhodes piano.
