Vaschide and Vurpas state (Archives de Neurologie, May, 1904) that in their experience music may facilitate sexual approaches in some cases of satiety, and that in certain pathological cases the sexual act can only be accomplished under the influence of music.
Féré, L'Instinct Sexuel, p. 137. Bloch (Beiträge, etc., vol. ii, p. 355) quotes some remarks of Kistemaecker's concerning the sound of women's garments and the way in which savages and sometimes civilized women cultivate this rustling and clinking. Gutzkow, in his Autobiography, said that the frou-frou of a woman's dress was the music of the spheres to him.
The voice is doubtless a factor of the first importance in sexual attraction among the blind. On this point I have no data. The expressiveness of the voice to the blind, and the extent to which their likes and dislikes are founded on vocal qualities, is well shown by an interesting paper written by an American physician, blind from early infancy, James Cocke, "The Voice as an Index to the Soul," Arena, January, 1894.
Long before Darwin had set forth his theory of sexual selection Laycock had pointed out the influence which the voice of the male, among man and other animals, exerts on the female (Nervous Diseases of Women, p. 74). And a few years later the writer of a suggestive article on "Woman in her Psychological Relations" (Journal of Psychological Medicine, 1851) remarked: "The sonorous voice of the male man is exactly analogous in its effect on woman to the neigh and bellow of other animals. This voice will have its effect on an amorous or susceptible organization much in the same way as color and the other visual ovarian stimuli." The writer adds that it exercises a still more important influence when modulated to music: "in this respect man has something in common with insects as well as birds."
