okay basically I need help figuring out which daduk (which key) to get:

I'll be playing with a strumstick tuned to D (DAD), and a Zurna tuned to Bb, along with a Tambourine and some percussion. I'm not very great with music theory, so I'm not sure which would be the ideal key to get it in (I'm thinking A?).

that site is not working for me


though Bb major would work with the notes Bb, A and D
or Bb lydian (which is F major)
