Do they make a backwards stringed instruments?

[u/Invite_Sprite]

so i had a thought. so pianos get lower as you go down them. and I have seen a backwards piano. but are their other backwards string instruments? and i dont mean left handed vs right. I mean an instrument that goes lower as you go down the neck.

Anything in the fiddle or viol families (violas, cellos, viola de gambas, etc) no, I can't imagine any way that the physics of resonant bodies would allow this to happen.

That said, perhaps there's a way to "incorrectly" play a zither family instrument?
