APPENDIX D
Evidence in Regard to Musical Imagination[165]
The question asked above,[166] Does the experiencing of purely musical sounds evoke images, universally, and of what nature and under what conditions? seemed to me to enter a more general field—the affective imagination—which I intend to study elsewhere in a special work. For the time being I limit myself to observations and information that I have gathered, picking from them several that I give here for the sake of shedding light on the question. I give first the replies of musicians; then, those of non-musicians.
1. M. Lionel Dauriac writes me: "The question that you ask me is complex. I am not a 'visualizer;' I have infrequent hypnagogic hallucinations, and they are all of the auditory type.
"... Symphonic music aroused in me no image of the visual type while I remained the amateur that you knew from 1876 to 1898. When that amateur began to reflect methodically on the art of his taste, he recognized in music a power of suggesting:
"1. Sonorous, non-musical images—thunder, clock. Example, the overture of William Tell.
"2. Psychic images—suggestion of a mental state—anger, love, religious feeling.
