I'm going to ask you for the impossible but please take my question seriously. I need your help in teaching myself to get from the F on the top line to the high C. I know that's not just G, A, B, C, it's all the notes in between but I want to think about it as only four notes (which is incorrect but please bear with me).
Anyway, I just posted in another fresh self-study thread about my experience. Over the course of two years I studied trumpet on my own on and off. I now can hit the F on top of the stuff. I don't push myself, I use minimal MP pressure and I try to play relaxed as much as possible.
I don't remember how I got to F on the top line though I remember hardly hitting the middle G two years ago but also I don't remember what was in between. I remember that I tried to reach a little higher from time to time, when I felt it was possible. I don't know how I determined the exact moment but it worked... so far.
Now, when I got to the top line F about two months ago my progress stopped. It feels like I can play the F (not always in a stable relaxed manner but it comes out) but it feels like the G on top of the stuff is in another dimention. I've been trying to find the new moment to go for the G and every time I've been trying it over the course of last two months I failed.
I play D-F - it works, I try to play E-G and it simply locks up on G.
Any advice including 'find yourself a teacher' is appreciated
