It would be nice if I had been practicing the Stravinsky Concerto for Strings for months.
That way my intenstines wouldn't have to get all upset as we near the second movement. They tense and send signals to my right shoulder, which would apparently like to hide in my ear. The next in this mutiny of the body is my brain, which decides there are just too...many...notes.... and refuses to translate any more accidentals or remember any fingerings. A-flat or A-natural? Huh?! HUH?! Hey, is my bow still moving?
It's better today, but of course today we rehearsed the Brahms instead. Sigh.
