What could cause grunting (when two tones are sounding at the same time, the actual tone and also a lower one) only on B4 (middle line B), not any other tone? None of the four lowest pads are leaking.
I adjusted the register key to a somewhat smaller opening between the pad and its tone hole, and it seemed to help, but I'm not sure if this was a complete fix. As I've understood previously, a too wide opening of the register key may cause grunting in the upper clarion, but not primarily in the lower clarion - or exclusively on the B4. Thus I'm a bit puzzled.
Any ideas about the cause or a fix?
The above concerns a well used but recently overhauled student clarinet, an older plastic body Yamaha.
I would also like to ask about another grunting problem, on a professional level clarinet that I had for trial a while ago. On this clarinet, the grunting was mostly on e5 and the notes around it (from c#5 to g5, but mostly on d#5, e5 and f#5). It appeared primarily when tonguing (either single or double), but sometimes also when playing legato. Also in leaps from the third register down to the second register, but sometimes also when leaping from the second to the first register (then occurring on notes around low a).
This latter clarinet had a very wide bore, measuring 15,95 mm at the upper end of the upper joint and 15,25 mm at the lower end, but I don't know if this had anything to do with the grunting.
The problem was the same with two different mouthpieces, a Maxton HH1 and a PlayEasy A'.
Any ideas about a cause or fix also in this latter case?
