Music in an american high school?

It is not uncool to do music! Do it! But anyway, if you own the instruments, then you can use those, but if you need an instrument, the school should either provide you with one or you'd have to rent one from an music store the school is using. Where I go to school, you can either rent or buy the instrument from the music store that the school uses. that's where I also get my piano lessons, so the music store should have private lessons. At my school, they also have music theory cles, three school bands, a jazz band, br choir, marching band (woo!), pit band for the musical, and there's probably more there I forgot about. With choir, we have three or four choirs, and the musical which I just auditioned for yesterday! Band like in movies about high schools make them look geeky, but there are a ton of popular kids in band. You meet a lot of new people through musical stuff at my school, and band and choir is so much fun! Good luck, keep tooting that horn, belting those notes, and welcome to the US! :)
