I've been playing for about 4 years now, and recently i feel as though i cant play for very long playing through concerts ( I have to cut back on my playing and even take breaks to conserve for My solo [Remembrance day])
You know how when you learned to play and all the guide i find, it's start with just your lips buzzing...right? Well, When i first joined band.... I could do that.
Now when ever I do it it either is just air, or something just out of this world.
I'am not quite sure what to do now, no i don't have a trumpet teacher.
