Hey Burning Down, nice to meet you!
Well I just make compositions on my piano, the kicker is trying to write them down on sheet music, there's so many rules you have to follow. I play fairly well by ear but I really would love to be able to chart out everything I do on paper just because it will help me write more complex pieces in the future.
I was just recently studying music at a university, but I came to the realization that there was nothing the school was teaching me that I couldn't tech myself, and IMHO I just feel you don't need schooling to be a great musician. Plus I felt like I was being held back from my writing because school took up most of my day.
That's pretty awesome that your arranging music of your university........ but it's a shame your only doing pop songs. lol
Well here's to hoping you'll get to compose your own music in the future!
Good luck!
