So, we know that the tongue is a muscle. Is it the end result of what you hear- I think not. For example if I stepped on your big toe and told you not to think about it - what would you do? So, perhaps we could think of how we want to pronounce the sentence - hear it as you would the words in a sentence- whether it be Ta, Da, Du, you want to keep you imagination as far forward as possible - and allow the pronounciation to float on the air. Remember , you don't order up air, you don't order up tongue- You Order up Song - stop making causes out of the END RESULT. Believe in WhAT YOU WANT TO HEAR rather than reacting to what might happen. Peace, DT
