Addendum to "No Longer Toothless"

So, I went to choir rehearsal last night. I didn't realize how much I had been working around that hole in my mouth when I sang. I knew that sometimes my tongue would vibrate around the hole, but last night I realized that I had subtly changed the position of my tongue to avoid it. Now I will do a bit of re-learning. I'm sure it won't take long though.
