I am so grateful for all of this great information from other players. I have studied with many good players and non of them ever mentioned any of this to me. I decided to break my playing down into heavy days and light days. The light day(today) was spent playing from the Mitchell Trumpet Method Bk1. I have had this book for several years and never touched it until today. What a great book. I got in 21/2 hours and my chops felt great. Tomorrow is my "heavy" day. I will work on Lesson I from the Maggio Studies. I studied with Carlton MacBeth, very briefly, 30 years ago. I am definitely going to watch my fatigue levels tomorrow. Thank you all so very much. Peace and many gigs.
