I’ve returned to the basics recently….. Backswing, Slingshot, and Tissue exercises. I’m probably doing about 100 of these per day and the results have been amazing.
I would suggest that you reinforce the basics before trying to move ahead.
I perform on a cruise ship and we had around a week of rough seas. Since it was difficult to practice, I decided to spend more time on the basics without the horn. It helped so much.
