The physiological effects of music and breathing, both together and individually, have been studied for decades. But in recent years clinical testing has come up with some very impressive results.
These results have been published in respected medical journals around the world including Circulation, the journal of the American Heart Association, the Journal of Clinical Hypertension, American Journal of Hypertension, Journal of Human Hypertension, Hypertension Research (Japan) and many others.
Slow breathing with music has won considerable medical recognition. It is used, endorsed and/or taught by leading institutions including Harvard, Medical School, The Mayo Clinic, John Hopkins, Rush Presbyterian Hospital and the American Heart Association among many others.
It's easy to see summaries and results of testing for yourself. What follows below is just a small sample of the available documentation. Just click on any of the links to access the actual journal articles, most of them posted on the website of the National Library of Medicine and the National Institutes of Health:
