Seeker of truth and beauty
A quick bit of advice. You should continue doing tone exercises even as you become intermediate and advanced. A regular part of your practice routine. Long tones and overtones. You will build your embouchure and a nice tone but you have to maintain it. I once read an analogy that said long tones are to your tone what water is to plants. You have to water them to make them healthy and beautiful. You have to continue watering them so they stay that way.I have signed up for an online course and have spent the day absorbing as much info as I can. A few short goes (will take a while to build up the face muscles) and pleased so far. I have been practicing the embouchure and getting nice consistent sounds now. Then did a few scale. I will keep doing that for a few days until the muscle memory is there and then shift onto learning some pentatonic scales.
I know you are just starting but I wanted to give you a heads up on that,
