Over the past few months I've been using air compression to develop my range better and more efficiently, not only are my high notes stronger, but I'm saving a lot more on my chops by not using physical pressure. But now I have an extremely hard time hitting notes from a high G to a high C as opposed to Double High G and Double High C, and it's not making any sense. And sometimes even getting a note to sound from that range is even more difficult, and I'm trying not to analyze too much into what I'm doing, but I've never had trouble hitting these notes before and I'm not sure why I suddenly can't even get them to sound. I doubt this has happened to anyone before, but I'm extremely lost. I'll bring this up to my private teacher when I have my next lesson again in the middle of January, but I'm worried about this now that I have All-State Band rehearsals coming soon. Thanks for reading and I hope you can help!
