My theory isn't terrible...well, when I was actually studying and in the groove of things I was decent for a singer with little instrumental background but what would mostly kill me is rhythms...some of that stuff you guys choke down boggles my mind. Like I'm sure I could get used to recognizing and reproducing it if I worked hard to get more acclimated at it, but dear lord I look at a band score and cry half the time.
Can you do Bulgarian rhythm? It's 2+2+3. I find it easy. I'm just good with rhythms for some reason.
