Nat Hentoff in a jazz.com article revealed that the late jazz musician Louis Armstrong, believed strongly in the healing power of music and sent recordings of jazz and classical music to a hospital in New Orleans to be played for women during childbirth.
In addition, there is a Louis Armstrong Department of Music Therapy at New York's Beth Israel Hospital funded in part by the Louis Armstrong Foundation. It treats patients in pediatrics, oncology and other specialities.
