Matthew,
Good work this week! I know it’s a little frustrating getting your new-ish embouchure set up but as you proved to yourself in your lesson – it’s working!
This week work on short regular practice sessions 5-10 minutes max! Work on smaller chunks of the low F study and Georgia on my mind (2-4 bars at a time) focusing on your sound. Make sure you are taking a full breath and that your head is balanced on your shoulders.
Also, take a listen to a few of these clips to get an idea of what you are working towards (long term) with your sound. If you have a solid idea of what you want to sound like it’ll be easier to produce that on the horn!
