Here's some information from the MHTP site:

"The founders of MHTP had a clear vision as to the purpose of the program. MHTP's objectives are charitable and educational, which include: Serving the critically ill and dying with live music to promote healing or assisting in the life/death transition; Providing the same service to all those for whom it is of benefit; Teaching the practice of this service; Establishing programs and centers for service and education at various locations; Publishing information, research findings and other material concerning the service; Developing affiliations with healing, charitable and educational organizations where this service may be given and learned."
