I have a space in my front teeth, which, I understand may perhaps be an asset. I can force air through the teeth at high velocity, but my upper lip generally blocks the air flow with the traditional rolled-in embouchure. I do pull the lips in a bit. My current range goes reliably to high C, sometimes D. I have been playing trumpet for almost two years, but really got serious about nine months ago, with a couple of hours practice most days. Is there a different embouchure I should try in order to exploit the space in my front teeth? The space is not too wide - but I can tightly pass a flat toothpick all the way through it vertically. The space is straight, not upside-down "v" shaped, as I understand is optimal.
