I am 60 now and have played music since I was about 6, playing professionally, on and off, from age 14, and like MetaGeorge, music is very visual for me. I see scales, keys, timbre, rhythm, timbre, everything.
But for me a photograph is a glimpse into silence, even photographs of scenes that are noisy. I have never associated music with anything visual, not painting, sculpture, photography, nothing.
And I never listen to music in the darkroom. It is either silence or talk radio. After a long session, I often play some music (not a recording, I mean an instrument) to relax.
