What ways are there to view and or record growth in musicianship and trumpet playing? I've heard about recording tounging speeds, marking music to show endurance, ect. I'm looking for just little things I can do to keep the spirits up on days where I'm not feeling too hot with playing. Something I can pull out to prove to myself that I am getting better and motivate myself. Also just to see personal growth so I can really push myself to grow more everytime I pick up the horn. Thoughts?
