For the majority of last week (unwillingly) I took a break from playing .
I was working at a camping concert festival and wasn't willing to bring any of my horns (don't have a beater ... yet)
My main observation about this came yesterday - I did not lose any of the important parts of my playing. Sound, music, majority of my technique (including range) were unaffected. I just lost the extremes - hence my once again realization:
Trumpet playing is not about muscle, or beating yourself up. Its about refining the balance of breathing and knowing what you want to hear.
That said, my endurance has been shot and I'll spend the next couple of weeks getting it back...
