I am wondering if there is a way to control if I am playing the correct half holed notes on my duduk.
During practise it sounds just awful ;-)
What is the recommended practise to keep the halfholed notes (and others) in the correct tuning?
Half holing is not easy, but a very good help would be , to use a tuner, either buy one or use a free online tuner via the internet
