Hi, I'd like to hear different opinions about a problem I've been having these past few weeks with my horn playing. From middle C to G, I feel like my sound is too "airy", and the vibration inside the mouthpiece is big and off-center. Also, in the highest octave, I’m playing too high in pitch. I think it might be due to accumulated fatigue or a lack of focus in my playing technique. I’m doing some simple drone exercises to try to center the sound. Any tips? Thank you very much!!
