How low can the top arching be?
What would be the acoustic effect?
(I remember reading somewhere that lower arches increase the intensity and the number of wolf notes.)
And most important in this context, what type of wood is needed? Or in other terms, I don't think that one can make an extremely low arching with wood of low rigidity,
On the practical side, would it be enough to take the bending properties of a test strip as a guide line to form an idea of the arching height? (Something like: the stiffer the material the lower the arching)
It would be interesting to know from MN followers how low was the lowest arch ever made?
