Hmm, I'm play percussion in my high school band, so i have to say that. However, I really like techno/electronic/house music so electronic is another possibility. In addition, I like the ability and feel of a guitar and I'm also a big fan of classic rock, so that too.
I could go on but I'm going to have to say I love each instrument and all types of music. I'm very big on music (even if my parents aren't). It will be the only thing or one of the things that I will force on my children. They'd gotta at least play a instrument.
