I bought a Moldavian kaval in Eastern Europe a couple of weeks ago. This was the five-hole type, played in the octave, twelfth and double octave registers, usually with a hummed drone that gives it a buzzy sound. I've mislaid the maker's fingering chart, he seems to be away from his email at the moment, and it it didn't seem quite right anyway. Anyone got a full-range fingering chart for the thing?
As far as I can tell, which note you hum doesn't make a lot of difference to the effect. Some players vary the pitch of their hum, most don't.
I have Andras Hodorog's CD - that's the sort of tune I want to play on it.
I've seen the discussion on Chiff & Fipple. Typically bozoid for that site.
