I have found little evidence to show that music, except in occasional cases, exerts even the slightest specifically sexual effect on men, whether musical or unmusical. But I have ample evidence that it very frequently exerts to a slight but definite extent such an influence on women, even when quite normal. Judging from my own inquiries it would, indeed, seem likely that the majority of normal educated women are liable to experience some degree of definite sexual excitement from music; one states that orchestral music generally tends to produce this effect; another finds it chiefly from Wagner's music; another from military music, etc. Others simply state—what, indeed, probably expresses the experience of most persons of either sex—that it heightens one's mood. One lady mentions that some of her friends, whose erotic feelings are aroused by music, are especially affected in this way by the choral singing in Roman Catholic churches.[[127]]
In the typical cases just mentioned, all fairly normal and healthy women, the sexual effects of music though definite were usually quite slight. In neuropathic subjects they may occasionally be more pronounced. Thus, a medical correspondent has communicated to me the case of a married lady with one child, a refined, very beautiful, but highly neurotic, woman, married to a man with whom she has nothing in common. Her tastes lie in the direction of music; she is a splendid pianist, and her highly trained voice would have made a fortune. She confesses to strong sexual feelings and does not understand why intercourse never affords what she knows she wants. But the hearing of beautiful music, or at times the excitement of her own singing, will sometimes cause intense orgasm.
Vaschide and Vurpas, who emphasize the sexually stimulating effects of music, only bring forward one case in any detail, and it is doubtless significant that this case is a woman. "While listening to a piece of music X changes expression, her eyes become bright, the features are accentuated, a smile begins to form, an expression of pleasure appears, the body becomes more erect, there is a general muscular hypertonicity. X tells us that as she listens to the music she experiences sensations very like those of normal intercourse. The difference chiefly concerns the local genital apparatus, for there is no flow of vaginal mucus. On the psychic side the resemblance is marked." (Vaschide and Vurpas, "Du Coefficient Sexual de l'Impulsion Musicale," Archives de Neurologie, May, 1904.)
It is sometimes said, or implied, that a woman (or a man) sings better under the influence of sexual emotion. The writer of an article already quoted, on "Woman in her Psychological Relations" (Journal of Psychological Medicine, 1851), mentions that "a young lady remarkable for her musical and poetical talents naïvely remarked to a friend who complimented her upon her singing: 'I never sing half so well as when I've had a love-fit.'" And George Eliot says. "There is no feeling, perhaps, except the extremes of fear and grief, that does not make a man sing or play the better." While, however, it may be admitted that some degree of general emotional exaltation may exercise a favorable influence on the singing voice, it is difficult to believe that definite physical excitement at or immediately before the exercise of the voice can, as a rule, have anything but a deleterious effect on its quality. It is recognized that tenors (whose voices resemble those of women more than basses, who are not called upon to be so careful in this respect) should observe rules of sexual hygiene; and menstruation frequently has a definite influence in impairing the voice (H. Ellis, Man and Woman, fourth edition, p. 290). As the neighborhood of menstruation is also the period when sexual excitement is most likely to be felt, we have here a further indication that sexual emotion is not favorable to singing. I agree with the remarks of a correspondent, a musical amateur, who writes: "Sexual excitement and good singing do not appear to be correlated. A woman's emotional capacity in singing or acting may be remotely associated with hysterical neuroses, but is better evinced for art purposes in the absence of disturbing sexual influences. A woman may, indeed, fancy herself the heroine of a wanton romance and 'let herself go' a little in singing with improved results. But a memory of sexual ardors will help no woman to make the best of her voice in training. Some women can only sing their best when they think of the other women they are outsinging. One girl 'lets her soul go out into her voice' thinking of jamroll, another thinking of her lover (when she has none), and most, no doubt, when they think of nothing. But no woman is likely to 'find herself' in an artistic sense because she has lost herself in another sense—not even if she has done so quite respectably."
The reality of the association between the sexual impulse and music—and, indeed, art generally—is shown by the fact that the evolution of puberty tends to be accompanied by a very marked interest in musical and other kinds of art. Lancaster, in a study of this question among a large number of young people (without reference to difference in sex, though they were largely female), found that from 50 to 75 per cent of young people feel an impulse to art about the period of puberty, lasting a few months, or at most a year or two. It appears that 464 young people showed an increased and passionate love for music, against only 102 who experienced no change in this respect. The curve culminates at the age of 15 and falls rapidly after 16. Many of these cases were really quite unmusical.[[128]]
