First of all, let's define healing: "the ameliaoration or lessening or improvement of symptoms as reported by patient." (definition by Dr. Cash) Healing does not mean curing. No one can claim to have a 100% cure for anything. Life is full of exceptions but guess what? As many people report healing from alternative or complimentary therapies as report healing from traditional Western medicine techniques, i.e., surgery, antibiotics, psychotherapy, etc.
If music is so powerful, why don't more people turn to it? Because they don't realize it's power despite the fact that 99% of people on the planet will tell you what kind of music they like...and don't like! Every culture that we know of has music that reflects that culture whether it's gamelan music in Asia, hip-hop in South L.A., or Western classical music in London or Vienna. We are hard-wired to produce and respond to music.
Soooo, is it that surprising that music can also be healing? Doesn't music help you to relax, to forget your troubles for a while at least? Doesn't music bring back wonderful memories and those old feelings or love or infatuation? Music therapist and music researchers in the health field have documented music's power to boost the immune system, lower blood pressure, and stabilize the heartbeat and breathing. Music connects people heart-to-heart.
So what are you waiting for?
