The hope of music's healing powers

Yes, yes, it hath charms to soothe a savage breast (or beast, if you prefer to repeat a common mistake). But researchers are finding that music may be an effective balm for many other afflictions: the isolation of conditions such as autism and Alzheimer's disease, the disability that results from stroke, the physical stress of entering the world too early.

The hope of music's curative powers has spawned a community in the United States of some 5,000 registered music therapists, who have done post-college study in psychology and music to gain certification. Active primarily in hospitals, nursing homes, special needs classrooms and rehabilitation units, music therapists aim to soothe, stimulate and support the development or recovery of abilities lost to illness or injury.
