When I was 18, science, physics, and math were my favorite. I was a bit of a nerd - the only girl with a lot of boys at chess championships.
BjorkI've written arrangements for choirs and strings in the past, but I usually write music with my voice or a keyboard and then I'll get someone who is good at writing scores to write it out. Or, if I have the luxury of time, I will go in a room and hear the people perform and then change it through what I hear, not on paper. I can read music OK, but I probably rebelled a little - music changes into something else when you read it.
