Well, I used to be in school color guard but I was really bad at it. ;-;
I've been playing the bassoon in the school band since sixth grade - I've been playing for almost three years. XD I wanted to play the flute in the beginning, but I just could not, for the love of potatoes, get any sound to come out of it. However, someone had me try the clarinet and I apparently was really good with the reed. Then that someone was like "You have long fingers. You should play the bassoon!"
I don't regret choosing to play it. Best, most fun instrument ever.
However, if I were to choose another instrument, I would choose the dizi (it's like a bamboo flute, usually seen in Asian cultures), the contrabassoon, or the bass clarinet.
