A thorough search of the history of medicine will show that almost all phenomena and substances have at one time or another been tried in an attempt to combat disease. Many of these agents were abandoned when they became unfashionable to a more sophisticated civilization, or were recognized as unwholesome by a more educated generation. The fact that few were given up merely because of their ineffectiveness can be seen in the great number of quack nostrums which still enjoy an active sale among the ignorant, and by the impossible claims of highly organized cults which continue to gain in numbers and followers in this country. Healing schemes based upon the use of herbs because they are delivered right from nature’s womb, or the fanciful notion that all diseases arise from the imaginary displacements of the spinal bones, are still in their ascendency. The liberal system we call democracy has not only permitted their growth but has rewarded their ingenuous and ingenious development. Exposure of the fraudulent methods involved serves little purpose because the mentality which is so susceptible to warped reasoning responds poorly or even antagonistically to enlightening guidance. There are, however, certain valuable features in herb and spinal doctrines which have been partially ignored by reputable physicians because of the intimate relation of these ideas to cult practice. In spite of a spirited rebirth of the movement towards the establishment of a system of healing based on music, there are many valuable uses of music in medicine which might suffer a like fate unless a critical analysis of the worth of music as a therapeutic agent is effected before Musical Therapy reaches the dubious distinction of classification as a healing cult. This book has been written with a view to preserving for medicine that which is good for patients, and in an attempt to aid musicians under medical guidance in using music to help the sick. Primitive peoples throughout the world still use music in association with the healing arts. This of course is an indication that they have probably used it for more centuries than are recorded in the pages of written history. Ancient civilizations frequently associated music with the divine, but placed diminished emphasis upon its association with healing. Even so, the Hebrews accredited to music curative and inspirational powers[7], as can be seen by the reference in Scripture: “And it came to pass when the evil spirit from God was upon Saul that David took a harp and played with his hand; so Saul was refreshed and was well and the evil spirit departed from him.”[63]
