I have been playing trumpet for many, many years. I have always had difficulty building up the strenght in my emboucher corners so that I could play comfortably in the upper register. I am thinking about changing my practice habits so that I can get more time for my muscles to recuperate. I am going to start practicing every other day. I am playing correctly - at least I thnk so. I find that when I am well rested, I start to have an easier time with playing above the staff and my sound is richer, and fuller. Changing mouthpieces has made no difference but the longer rest period has. I would welcome any oberservations or comments on this. Thank you.
