Ok, I have been trying to increase my range for some time. I have found the mouth piece that works best for me, that is, within the limits of getting a custom one made. Sound fairly simple, but just a regular old Bach 3C. It's comfortable and plays great for me. I love my horn plays great as well. So, I play well on all my tools and I have corrected my embouchure to a further extent (my bottom lips had an air pocket in it when I played). So, I want to increase my range because the further into school I ge tthe more demanding the parts are for me. So, I've always been told that if you develop your low range your high range will increase at the same rate more easily. So, the question. If this technique does work how do you develop you low range when you cna only play so low on a trumpet? Any tips? Thanks in advance guys and girls!
