just for you, i went to barnes and noble and looked only in the music section. i found a book entitled: 'Music, physician for times to come' which is an anthology compiled by Don Campbell. He is also a best-selling author of 'The Mozart Effect'
Some of the contributing authors include Roberto Assagioli, MD was a psychiatrist in italy who developed a comprehensive psychology he called "psychosynthesis."
Barry T. Brodie, Ph.D. leads a drama group called the earthstage actors.
Swami Chentanananada who studies and practices meditation and spiritual life, and is an initiate of the ancient saraswati order of monks.
Manfred Clynes, D.Sc. an academic leader in the study of emotional responses to music.
these are just a few.
now, for a little insight as to how involved you can get in this subject..."there is a pronounced idealization of the pre-natal environment in tomatis' work, an image of the womb as an auditory paradise, a condition of 'super hearing' to which we aspire throughout our lives to return." now, i don't really know how true this is since our ears are one of the last things to develop, but it sounds interesting! then it goes on to say "zoologists know something else well, that the ear, the vibration sensor, serves to charge the organism with electrical potential. it is thanks to the ear that external stimuli are able to charge the cortical battery." i've always felt charged by music, but never quite knew how to express this.
the book's a good read.
