Does positive musical vibrations activate some genetic materials in the brain?

Which genes are sensitive to the sound and resonance of music?

If it helps relieve stress, then I could see habitual exposure to music acting to change hormone levels and therefore possibly epigenetic expression as well. We know that fear can be inherited epigenetically in mice, so I wouldn't be surprised if something like this could have some heritable effect as well. I don't think it can actually affect the DNA sequence directly, however.

I would assume that all of the physiological responses to music happen at the receptor signaling level.  These responses COULD conceivably lead to temporary changes in gene EXPRESSION, but not ACTUAL genetic alterations.  I suppose that in the case of EXTREME (and likely repeated) exposure to a certain stimulus like music, epigenetic changes could occur that would be more permanent, but the DNA itself would still be unaltered.
