Im addressing this to luke but it is for anybody that wants to respond.
Luke, i went to a mirror with a flashlight to see what is going on inside my mouth. My tongue is rolled back like you did with the paper and i am trying to open my throat as much as possible but the space between the top of my rolled up tongue and the soft palate is very narrow. Is this right? Open throat yet narrow space?
My 3" is getting better. Thanks for all of your help and luke you are definitely the man when it comes to harmonica! You taught me how to bend!
