Many composers use the piano as their compositional tool, even when writing for other instruments (winds, voice, mallet percussion, etc.). Of course, you don't have to use piano to write, but if there's one instrument you should know how to play, at least a little, it's the piano. You'd be hard pressed to find a credible composer—or musician for that matter—who wouldn't agree with this sentiment. This section outlines the most salient elements of the piano together with some suggestions on how to write piano music in a variety of styles.
