Hello everyone. A friend of mine recently mentioned to me Claude Gordon’s KTM approach to tonguing, which I’d not heard of before. I’m experimenting with it and have a few questions: (1) With the KTM method, is the tip of your tongue supposed to be placed at the bottom or top of your bottom teeth? (2) Which of Claude Gordon’s books would be best to purchase to learn about and practice this method? (3) Is there another resource (e.g., other books or websites) that may be particularly good to check out for the KTM method? Thanks!
