I am a grade 8 pianist, and i'm interested in composing some small (half, 1 page) easy pieces for solo piano. This will be for my own pleasure, I don't want to be the next Chopin

. Having never composed before, or had any lessons in composition, i'd like some tips on how to achieve my aim. I'd assume my first step would be to choose a key in which to compose the piece, and a time signature. Once I have decided this, would it be better to compose the melody first, and then the accompanying left hand? Are there any golden rules I should know? Any help whatsoever would be good, thanks
