Since ancient times music has been used as an accompaniment to meals. The instruments used by the ancients for this purpose were usually those which emitted soft sounds. Voltaire said that our purpose in going to the opera was to promote digestion. During the preceding century, dinner music became stylized and consisted largely of semi-classical pieces or waltzes played softly in slow tempo by string ensembles. During the past twenty-five years there has evolved a form of dinner music which is not only a marked departure from the old, but has come to be used as a source for dancing between and during courses. Whether the physiologic and psychologic effects of dancing during a meal are harmful, beneficial, or of no moment remains undecided. Certainly there seems to have been little interest in analyzing its effects. During the period when dinner-dance music was available only in a few places, the number of those who could be affected by it was very small. But, with the more recent installations of “juke” boxes, and other forms of mechanically reproduced music, into all varieties of dining places, the problem is worthy of investigation. Most people derive pleasure from the consumption of appetizing food. Most people derive pleasure from music played to their taste. Although the logic of the following thought is subject to criticism, it does sound reasonable to state that two pleasurable experiences enjoyed simultaneously, should add up to a greater happiness than that afforded by either individually. Food has received thorough study with respect to preservation, preparation, serving, and the time of day when each item is most satisfying. Some of the conclusions have been arbitrary, but for the most part, people eat the food that agrees with them physiologically and psychologically. There is no especially good reason why cereals should be eaten by adults only in the morning. It has become a matter of custom or advertising, and the minds of the masses have become conditioned to feel that cereal is especially good at breakfast time. A generation ago the breakfast menu in some homes differed little from the present day dinner fare. Eating habits have become set in the minds of most people and there is little that can be done to change them rapidly. Daily routines have given rise to certain music conventions as well. Until recently, music at breakfast was uncommon. Bernard Shaw[65] wrote, “Music after dinner is pleasant: Music before breakfast is so unpleasant as to be clearly unnatural.” With the advent of radio this has changed even if Shaw has not. Lunch rooms, barbershops and other public places where people spend time inactively, are equipped with mechanisms for reproducing music. The practice of reading or even studying school work at home with the radio on has become increasingly prevalent. The tempo of living has stepped up to the point where most people, especially the younger, like to do
