dissatisfied

I just got home from my rehearsal. Well, I met Matt for coffee after I finished, so it's not just after my rehearsal really. But I was not happy. I felt like my playing sucked, like I was tense, and I was having trouble hearing. Partly that is due to the acoustics in the space, and partly because the piano I was playing, a nine-foot Kawai concert grand, has a tinny harsh sound in the upper register, and it was making me recoil. The only good thing about that piano is that it has ivory keys, and a nine-foot-concert-grand has great bass notes. But a bad rehearsal usually means a good performance, and vice-versa. So I should be happy that I thought it was bad. I guess...
