I'm really irritated when I mess up practicing piano. The slightest mistake will make me awfully frustrated and I'll get really angry. I hate hearing noise other than the piano when I'm practicing. I'm quite sensitive to noise when I'm playing the piano. Sometimes my Dad will whistle or snap his fingers when I'm playing piano and I'll get really mad. Usually, when I'm practicing, the outside noises are pretty quiet, but sometimes a door slams and really surprises me. It's funny when that happens, because all of a sudden there's this humongous noise that shocks my ear-drums. I usually stop playing for a few seconds because I'm so surprised.
When I get frustrated at something, I bang on the keys quite loudly.

Each time I make a mistake playing the piano, I learn something from the mistake I made. Every time I mess up, practicing the piano, I can pinpoint the places I need to learn better. Making mistakes is a learning experience for me. I like hearing loud noises when I'm playing the piano, because it makes me less prone to distraction when I'm playing at a concert or recital. It also builds up my tolerance of loud noises. Every time a door slams, I am less prone to distraction than I was a minute ago. So when I'm playing at recitals and concerts, I can focus on the music instead of the noises from the audience.
