I'm interested in learning what happens to people while they experience music & sound; what specific role sound & music has on human consciousness and what happens to musicians as they create music, like during an improvised jazz solo for example. I'm waiting on a few music psychology books that will hopefully lead me through my research this semester. Also a book suggested to me called "The Feeling of What Happens" by Antonio Damasio. An interesting site with some visual-music info: http://rhythmiclight.com/archives/timeline.html Here are some interesting theories I've stumbled upon... Synesthesia: http://en.wikipedia.org/wiki/Synesthesia#Sound_.E2.86.92_color_synesthesia http://en.wikipedia.org/wiki/File:Newton's_colour_circle.png Shepard Tone: http://en.wikipedia.org/wiki/Shepard_tone Damasio quotes T.S Eliot on consciousness saying that it is "music heard so deeply, that it is not heard at all."
