Edward Schubert Thanks so much for sharing Edward! Haha using a closet as a practice room... now that's what I call flexibility.... Also the camera quality looks super. 

Your pitch and sound are nice, so there are clearly some things working. Many of your attacks sounded fine, but a few were a bit fuzzy. I'm also hearing some noise in your sound when you play soft, and I think this is related. The second line sounded nice and full. By the third line, your sound was clearer and attacks more accurate, suggesting to me that this will definitely get better soon with practice! 

That said, a few suggestions:

- Throughout, you're playing a bit high on the pitch. Use a more open syllable in the throat and think "lower" to avoid getting tight. 

- The aperture may be a bit too tight, so consider allowing a bit more air out of the mouth. 

- The air stream may be uneven. To rule this out, hold a piece of paper 3 inches from your face and try to blow it with slow, consistent air so that the piece of paper is blown a consistent distance away from you. You can also use a breathing bag to help visualize this type of consistent air flow. 

- It's possible the air isn't being engaged at the same instant the lips are, so the attack sounds fuzzy/unaligned. I'd work on short staccato breath attacks on low notes (saying "ha" and trying to align the air and vibration until the attacks are clear). Try this across your range too. 

- In general, I'd do more soft playing with all articulation types in your warm-up, aiming for everything to be activated together, and for a more open resonant sound. Try doing Schlossberg like this for a few more weeks!
