Right now, my emphasis in all my pieces is how not to make them boring. But I still need quite a bit of understanding about what gives music the energy to move forward.  Sometimes harmony (which is a vast mystery to me) and sometimes rhythm.   We’re supposed to somehow know. One of the reasons I love this process is that it not only helps me with cello, but gives me an appreciation of how music  ‘works’ in all genres.   The more I don’t know, the less I’m bored.  It’s a good time to be alive.
