Music in the Key of Om is an album by Jack DeJohnette. It was recorded in 2003 and issued in 2005 by DeJohnette's Golden Beams Productions as the label's inaugural release. The album features DeJohnette on synthesizer, bells, and a new line of instruments developed in conjunction with the Sabian cymbal company, and consists of a single, hour-long track of ambient music intended for meditation and relaxation, a departure from DeJohnette's typical work in the jazz style.

Jack DeJohnette is an American jazz drummer, pianist, and composer.
