Yup, you can practice playing Tacet bars.
Practice being fully where you are and doing what's necessary in that moment.
Attention and focus are your most important tools as a musician. And it's not even close.
So, stop dithering around, driving everyone else around you to distraction and being a general nuisance. Show up on time, be relaxed, still and quiet and speak when you have something relevant to ask or say. Contribute intelligently and listen more. Listen more. When given a task, go diligently about your work. Help others with theirs once you've completed it. Be excellent at being in class.
I 100% Money Back Guarantee that will make you a much better musician.
Oh, and provide rim shots if anyone says anything funny.
