Mature amateur player here, aspiring to playing lead and improving tone on solos. I’ve been practicing daily trying to do at least an hour where possible, my high range has become more consistent and I’ve noticed improvement in endurance and embouchure strength. I’ve had an overbite and somewhat weak lower jaw, which I have been trying to work on moving forward to keep the lower lip more engaged. Can you pros recommend good exercises to help further improve this? It seems like I can keep it engaged for a while and this maintains my usual good tone, but later in long sections or concerts it gets more difficult and I sound sloppier. Your thoughts are appreciated.
