I’ve made good use of the exercises in your ebook and it’s helped immensely to say the least 🙂 and also really work on long tones a lot like you show on the lessons here on your home page. That’s the way I felt too, that I don’t have to learn to play the trumpet to improve my Saxophone tone. But his view was that felt it required more from the diaphragm to get a good strong tone on the trumpet than it does on the Saxophone. I, personally, wasn’t totally convinced about that, especially when watching people play Altissimo notes.
