Hello everyone of TM!
Just recently, i was practicing the lead trumpet chart for the song 'killer Joe' (ed wilson arrangement). There are a lot of High C's for long stands, and it is a true chop burner. Anyway, i just realised that i find it really hard to hold notes for a long time (on any level). I dont know whether it is a relaxation problem, or an embouchure problem. It is really a toll on any of my endurance and my playing.
When i play i have a really stressed looking face looking very similar to this: at 2:34 Lab 2011 HD Video Montage by the One O'Clock Lab Band - YouTube . I dont really know whether it is bad or not.
I also found out that when tuning my high 'c' (2 ledger lines), it is extremely sharp (almost a C#). I dont know how to bring it back, any tips?
Thanks a lot everyone for your help.
