This video features some things to try on the mouthpiece alone. These will help with your tuning. Be sure not to move your embouchure, just the inside shape of your throat and mouth. See me if you are really interested in mouthpiece drills. I don’t agree with everything he does in this video.
Pay close attention to how his throat area moves when he changes pitch.
Thanks Andy for finding this interesting video lesson.
Wow! They have awesome precision. I like how the two oboes have such distinct sounds, yet blend so well.
