"This music was composed specifically for the birth of my son Taro (January 13, 1993), and is intended to be used during the birthing process.The recording is a single track
"I started in Mary's obstetrician's office, by recording Taro's heartbeat on a Nagra portable field recorder, with a fetal pulse monitor attached to Mary's stomach. Back in the studio, the stereo tape was then transferred to a 16-track recorder and overdubbed. Rhythms were improvised on a Brazilian surdo, a low-pitched resonant double membrane drum. Next, Bobby Vega added bass harmonies. And finally Steve Douglas contributed subtle shadings on a western flute.
"The intent of this music is to facilitate and coordinate rhythmic breathing cycles, assisting the mother's concentration and focus before, during and after delivery."
