Tim, what I said earlier applies to all instruments. Have someone play and walk round listening carefully. You may be surprised where the sound comes from in some instruments. In a nice quiet, acoustically dead room, like a studio, you can place mics a fair way away to get a good pick up of the whole sound.You don't want to hear, strings, reeds, buttons or even breath, but the vibrating air produced therefrom.
This sounds simplistic, but remember that acoustic instruments are designed to project the sound.

Good luck I can see you are having fun already.
