I've been playing saxophone for 50 years, mostly alto but more recently tenor. Just recently I acquired a baritone saxophone, and I've had it tuned by a seasoned technician, so I'm pretty sure it's in great shape.
The issue is that, unlike my other horns, I have to loosen my embouchure to hit the lower notes without them jumping an octave. This seems wrong to me.
The horn did not come with a mouthpiece, so I bought a Yamaha 5C.
Is this slacking of the jaw normal for bari players when hitting the lower notes? Is it that I might have the wrong mouthpiece? Or is it me, and I just need to be playing more often to adjust?
Any insight will be greatly appreciated.
