In high school band (I was 10th or 11th grade I think), I played the alto sax, but since I could also play piano, my director switched me over to Glockenspiel for one particular song. I may have initially oversold my skill at piano (I'm really not that good), but as a brown noser and suck up, I was determined to make this work, so I stayed after school and spent free periods in the band room practicing. So I was pretty proud of myself when I could make it through the song without *too* many mistakes. A few weeks before our concert (so we were all pretty good but not fantastic yet), our band director wanted to record us so that we could all hear what we sound like together (you can't really hear that when you're playing individual instruments) and so she could play it for the parents at an upcoming parent/teacher night. I can't for the life of me remember what song it was, but it was very fast tempo, and the ending was pretty awesome for me - I had a cool run that (if played correctly) sounded really awesome, and the last beat I was told to hit the last note as hard as I could. So we run through it, it's sounding pretty good, but somewhere towards the end I somehow get a beat behind (and don't realize it). Everyone is supposed to end on this short staccato note together. One beat, everyone finishes together, then a split second later I come in and hit that damn bell/key/whatever you wanna call it HARD. And then a split second later (realizing what I've done), I yell "SHIT!" to a completely silent classroom. And was recorded. Whoops. I'm not sure if she ended up playing it for the parents or managed to cut my mistake out, but I got the stunned "LIS!" from our director and roaring laughter from everyone else.
