I practice piano and drums daily, except Sundays when I rest. This summer I'm practicing bass. My student Barb asked me, "how do you practice?" This is what I said.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
I'm a professional pianist and music educator in West Toronto Ontario. I'm also a devoted student and teacher of the drums.
