What defines a "musical experience," I wonder?
Let's assume it is primarily but not exclusively an auditory experience, from a sensory perspective. Air molecules are pushed around, exciting one's tympanic membrane, and the mechanism of your inner ear sends a tiny electrical pulse to your brain, which not only perceives but interprets the sound. That's of course a clinical description of hearing, but doesn't describe what happens to the person who is listening.
I'm making this a short entry today, because I want to follow up in more depth in a future posting.
