Learn all the noises your instrument can make and learn to use them musically. This skill is often underappreciated for no good reason. Learn to play "random notes", they sometimes sound much less expected then the ussual Yngwie runs. If you tap them, it sounds like a 50's SF movie spaceship interior. Contrast control with madness.

P.S. Try playing a piano that's badly out of tune. It's better than farting, everyone suffers while you enjoy.
