Well, I'm glad to read that there may be some other issue at work here. I have heard harmonic dissonance caused by instruments playing out of tune with one another, but I just wrote it off to...well...harmonic dissonance caused by instruments playing out of tune. Maybe this is an issue of words or wording...

...or who knows, maybe it's my hearing that needs to be tested. How many concussions can you have before it starts to effect your hearing?
