Yeah, I served up a pretty big clam this moring during Palm Sunday mass. The opening hymn had the adult and kids choirs, drums, brass, and strings playing together. There were some high C's spattered here and there in the trumpet part, and it was nice and bright and festive. The tune ends on a little run up to a high C# that's held for about 8 beats. Well, the C# came out nice and bright and loud as it should...and then it clammed down to about an A on beat 7 1/2. It wasn't nerves or lack of preparation, just a little extra spit in the mouthpiece that I didn't compensate for. Total user error on my part. I was mentally shot for the rest of the morning. All I can remember is that clam.
