Sing opera - or at least I'd like to. I did the foundation course (one evening a week plus a lot of extra time learning music) in academic year 2007/08 and loved it.
I didn't get into the diploma course because I have problems with my breath support and with acute stage fright, both of which I'm working on. The jury is out on whether the support will ever get sorted; if it doesn't, then I'll have to find a different style of music to sing.
None of this is in a professional context.
