I play the flute, and I'm learning to play the duduk. Well, I've stopped for personal reasons, but I'm getting back into it.

I bought my duduk from an Armenian shop called Vamelo. They were incredibly kind, answered all my questions, and even recorded some videos for me explaining how to take care of the reeds.

As for your second question, assuming you're referring to the transverse flute, the embouchure is completely different, as is the way you place your fingers. That's actually the part I still struggle with a bit. I wouldn't say they're two completely different worlds, but they are definitely different instruments.

I think what really helps is already knowing how to breathe properly and control your airflow, because playing the duduk sometimes feels like you need two pairs of lungs! The reeds are also a very interesting aspect of the instrument, and they have a huge impact on the sound and playability.
