Practice Makes Perfect?

A Drabble (exactly 100 words) about a horn.

My friends are going to do it, so why not, I figured. Learn to play an instrument, and try out for the school band. My dad played a tuba in high school, and his old one now sits in the garage attic. Oom pah, oom pah. I mean, how hard could that be?

After about three days I'd learned how hard. My cheeks hurt, my fingers hurt, and the cat was now hiding under the sofa. But the school year starts in a month, and I really want to be in the band.

So maybe I should try the tambourine.
