My lips are swelling after each session so I’m having to take long breaks. I’ve made sure my setup is good, there’s adequate pressure but not excessive, correct horn angle, and a warm-up session.
I’m using the time for ear training and working on fingerings but I feel like I need more time on the horn. This is my longest rest session: 3 hours. I’ll work on low chromatics and I’ll rest as much as I play (a favorite phrase of Claude Gordon).
