I started matching the pitch of middle C and am slowly working my way up the treble clef. The race between the Turtle and the Hare is quite appropriate at this time. The interesting part of being human, is the urge to run when we can barely crawl. There is a lot of humility involved when learning to crawl.
I try to match the pitch with the mouthpiece. I use the trumpet to check my embouchure – that my facial muscles are set in the exact way I need to produce the middle C pitch. This activity provides hours of entertainment.
Remember: a growth mindset!
