“Underneath of the story is the rest point. The place inside yourself undivided...”

Restore Your Field.

BioTune™ is the Sound Frequency methodology created and independently developed by Cass Phelps, integrating original sound-frequency recordings with somatic awareness, meditation, Biological Breath™, vocal sounding, and subtle fluid-body movement.

Phelps began developing this distinct body of work under the BioTune name in 1998, introduced it publicly in 2003, and has offered BioTune recordings, programs, instruction, and related services in commerce since 2007.
