"Can you make that sound better?"
Hmm, so simple it seems silly. But.....it worked.
I tried it today in a few lessons. When the student seemed to be wrapped up in some detail or other, I'd simply suggest, "Can you make that sound good?" or "Make those notes sound good."
..... it worked every time.
Shouldn't this be obvious??
Still, I even tried it on myself and...it worked.
Sometimes the simple stuff is the most profound.
In your next practice session, remind yourself, "Make each note sound good."
As Jacobs would say, "Make every note worth $50."
(of course, with inflation, each note has probably risen to $72.50 or, if you're using gas prices as a model, $465.99)
