Hi guys, recently I purchased a Bach 72 Large Bore B-flat horn. I enjoy the sound it makes, as well as many other features. However, I find that when I play this horn, I end up getting a lot more throat tension/restriction than usual. I attribute that probably to the large bore size, although I'm not positive. I have been finding that endurance in the upper-register is tough. In fact, I find it hard to make it all the way through a Charlier study (2, 5), which is a little odd for me. Today I was experimenting and I found that using more air helps somewhat. I know this is probably obvious, but I was wondering who has had experience playing large bore b-flat horns more effectively.
P.S. - Mouthpiece is Bach 3C #26 Throat
