Hello, first time poster here. Being that I am 57 years old now I feel that I have a limited time to play the trumpet or even trying to improve, I feel limited there too.All that being said maybe a little background, I played 1-3 chair in the trumpet section in high school, I could have been 1st chair consistently if I would have practised more and wasn't fearful of competition. Since high school I have been hit or miss with playing, my playing consist of playing in church and that might be just 4-5 times a year. I would like to improve my playing in the upper registry some, (nothing crazy high though) but a couple or three notes above high c. Right now I play LaBlanc 707 sonic, and to tell you the truth, I don't know if it is a decent trumpet or not, but I believe I have good tone quality with it as long as I practise consistently. After looking at youtube videos about proper mouth/lip position I'm not sure that I have ever been taught that, which has lead me to consider the pencil method. Would I see a difference in anything with a higher end trumpet?
