The same principles of stress, distress, diseases, disorders, and disabilities apply to adults, but there is an even greater variety of problems, a more complex overlap between these categories in the adult human animal.  So far as the “Three-D’s” (disease, disorder, disability) are concerned, someone has said that the average adult in the USA today has at least one “chronic” disability, disease, or disorder in youth, two in middle-age, and three or more in old age.  Music in therapy with adults has had its most important development and widest acceptance in the realm of behavior disorders.  Music therapy with older persons, “geriatrics,” was reviewed as a useful, constructive, and rehabilitative therapy as well as a possible vehicle fro influencing a change in attitude on the part of the general public in this country toward older persons.  This attitude, on of “obsolescence” toward aging people, needs to be changed if older citizens are to enjoy their later years and continue to make the contribution to society as a whole, of which they are capable.
