There can be no doubt whatever that music has the most remarkable effect, not only on our minds, but on our bodies. Physiologists tell us that different kinds of mental activity are carried on in different parts of the brain, and that, in order to recover from fatigue, we need not rest altogether, but merely take up some other kind of work. Hundreds of times I have found that, however much I may be fatigued by a day's brain work, I can play all the evening, or attend a concert or opera, without in the least adding to my fatigue. On the contrary, in most cases it disappears altogether, the music acting on the mind as a surf bath does on the body. Like many others, I have found that the best way to cure a headache is to attend an orchestral concert. It works like a charm. It stirs up the circulation in the brain as a brisk walk does in the body. Even brain disease is eased in this way. The power of music even to cure insanity altogether, was frequently maintained in ancient and mediaeval times. This claim is doubtless exaggerated, yet there is more than a grain of truth in it. There can be no doubt that violent maniacs can be calmed, and melancholy ones cheered and soothed, by music. To get an authoritative opinion on this subject, I wrote to Dr. Hammond. He answered: "I know of no cases of insanity that have been cured by music, but I have seen many cases in which music has quieted insane persons, exerting the same calming influence that it does on most of us when we are irritated by petty annoyances." "When we are irritated by petty annoyances." It is then that music becomes a medicine and a moral tonic. Writers on ethics have, hitherto, too much overlooked the moral importance of health. Where there is a lack of health, we rarely find any moral sweetness of temper. The vices may be small and peevish, but in their aggregate they are enough to poison the happiness of the household. If a man comes to ruin from drink and the crimes it leads him to commit, we call him immoral. But is he not also immoral if, from excess of work and worry, and wilful neglect of exercise, rest, and recreation, he breaks down and beggars his family, becoming a burden to them instead of a help? I think he is, and that, instead of pitying such a man, we should censure him. Ignorance of the laws of hygiene, physical and mental, is no valid excuse. He can buy a book on the subject for one dollar. But he does not even need to do that. Music, we read in Shakespere, has the power of "killing care and grief of heart," and what he needs, therefore, is to hear some good music every evening, at home or at the opera. This will draw the blood from the over-worked part of his brain to another part, and by thus relieving it of the tormenting persistency of worrying thoughts and business cares, enable him to enjoy refreshing, dreamless sleep afterward. In this way music may help to restore his health, cure his dyspepsia, and sweeten his moral temper.
