What's truly exciting is that science has begun to explore these ancient rhythmic connections that have stood at the heart of culture, spirituality, and healing for millennia. Today, the study of music in medicine is a rapidly expanding field, and it's taking it beyond complementary, supportive therapy. A growing number of published studies show that music can play an active role in health and disease. An even larger number of books have been written for general readers, highlighting the numerous and remarkable benefits of music and sound. From increased healing, spirituality, and personal growth to improved cognitive ability and greater emotional stability, music and sound therapy can make a powerful difference in people's lives. --Isaac Eliaz, M.D., integrative medicine pioneer.
