Wow, your asking about the best question one could. Resonance and bone.
Ultrasound scans make for some medicaly useful pics. Hows those corresond to a wood ultrasound? I havent a clue, but would be neat to know,
If you where asking about carving a body out of giant mammoth bones. My main question would be what kind of glue does one use to fit the 2 peices together if you couldnt manage a 1 piece mammoth bone bass body. Then Id have to ask what kind of changes to the screws need to be made since its wood neck to bone body and metal hardware to bone body. Are you going to do freaky bone headstock with spikeys? Might look kewl. But dunno about what kinds bone to wood glue youd need to make it work, Maybe superglue comes to the rescue?
Anyway, back on topic. Bone can resonate very well in some cases. However, unless its fossolized, yer gonna hava e heck of a time curing it. To make it ready for bass body. Bones have been used for flutes, whistles, and drumm things to include knock two together style play. However in these cases its been more high pitched rather then low pitch. Not many examples of mammoth tusk bass flutes are there? Bummer
I dunno. If you cure the bones properly, and can make the body out of 3 or less peices. And , lo heck maybe go with neck thru body neck from Carvin and just make wings for it as better route. Fewer headaches.
Body wings might work if one peice each. Was it a big elk?
