A number of experiments of the kind desired by Goblot had already been made by A. de Rochas in a book, copiously illustrated by very numerous instantaneous photographs, entitled _Les Sentiments, la Musique et la Geste_, 1900. Chapter III. De Rochas experimented on a single subject, Lina, formerly a model, who was placed in a condition of slight hypnosis, when various simple fragments of music were performed: recitatives, popular airs, and more especially national dances, often from remote parts of the world. The subject's gestures were exceedingly marked and varied in accordance with the character of the music. It was found that she often imitated with considerable precision the actual gestures of dances she could never have seen. The same music always evoked the same gestures, as was shown by instantaneous photographs. This subject, stated to be a chaste and well-behaved girl, exhibited no indications of definite sexual emotion under the influence of any kind of music. Some account is given in the same volume of other hypnotic experiments with music which were also negative as regards specific sexual phenomena. It must be noted that, as a physiological stimulus, a single musical note is effective, even apart from rhythm, as is well shown by Féré's experiments with the dynamometer and the ergograph.[94] It is, however, the influence of music on muscular work which has been most frequently investigated, and both on brief efforts with the dynamometer and prolonged work with the ergograph it has been found to exert a stimulating influence. Thus, Scripture found that, while his own maximum thumb and finger grip with the dynamometer is 8 pounds, when the giant's motive from Wagner's _Rheingold_ is played it rises to 8¾ pounds.[95] With the ergograph Tarchanoff found that lively music, in nervously sensitive persons, will temporarily cause the disappearance of fatigue, though slow music in a minor key had an opposite effect.[96] The varying influence on work with the ergograph of different musical intervals and different keys has been carefully studied by Féré with many interesting results. There was a very considerable degree of constancy in the results. Discords were depressing; most, but not all, major keys were stimulating; and most, but not all, minor keys depressing. In states of fatigue, however, the minor keys were more stimulating than the major, an interesting result in harmony with that stimulating influence of various painful emotions in states of organic fatigue which we have elsewhere encountered when investigating sadism.[97] "Our musical culture," Féré remarks, "only renders more perceptible to us the unconscious relationships which exist between musical art and our organisms. Those whom we consider more endowed in this respect have a deeper penetration of the phenomena accomplished within them; they feel more profoundly the marvelous reactions between the
