What Johnny is saying is the same thing my local Sax instructor had told me. For me, the ‘sweet spot’ was always where the curvature of the MP facing length comes in contact with the reed–it’s right at that point where I put my top teeth, use my bottom lip as a cushion and create a seal around the MP with the sides/corners of my lips. Any more than that, it felt like I had too much of the MP in my mouth. If I had less of the MP in my mouth, I couldn’t get enough air into it.
