Teardrop Dulcimer Question

08/31/17 09:36:53PM

If you have a Teardrop shaped dulcimer, (or make them) what is the span of the teardrop dulcimer at it's widest point?

I was asked to build one and am pondering how wide to make it. (My hourglass ones are generally 8" wide across the lower bout).

I am attaching a sketch of my basic design idea.

Thank you!
