At 6'2" 185 lbs. I'm not exactly "bony" but I notice most electric guitars and basses rest — or bang if I'm jumping around the stage — against the upper part of my pelvis. My Iliac crest to be precise.
Women have it worse. By happy accident of nature, they tend to be the ones who bear children, and thus (as a compensatory mechanism) possess a pelvis suitable for accommodating a fetus. Even a nine pound squirming one, as my sister-in-law just experienced. When mixed with bipedalism, one ensuing result is the female Homo sapiens sapiens has an even more prominent Iliac crest than the male.
As you know, the solid body instruments I build tend toward sculptural. I'm always playing with the form, in an effort to wrap the instrument around the musician's body. In conceptualizing Dove, I thought it might be interesting to create an additional cavity on the concave back of the instrument specifically to accommodate the pelvis.
Ah, heck — why not really experiment — and continue the cavity through to the front of the instrument? Make it an aesthetic feature as well. Differentiate the abstract dove's "wing" from her "body."
A structural hole. Hip hole.
