Thanks Rod. It is certainly worth a try. I don’t worry about the tongue ordinarily, but the book talks about this, so I brought it up. I will try some legato stuff. That is probably a great way to get a feel for what is bothering me about my tonguing.
By “contact the lip and change pitch” do you mean the tongue comes in contact with the lips and changes the pitch? I find that hard to visualize. How would touching the lips with the tongue change the pitch?
