The strait line in nature does not really exist. Even light bends around objects. On a guitar the one thing that could be truly thought of as straight is the stretched string, yet it is the oscillating string that powers the instrument. The defiance of the straight line could arguably be the basis of the whole concept of a guitar. This concept makes the notion of curving braces seem quite attractive on an artistic, metaphysical level. Curved or falcate shaped braces have a better stiffness distribution, making for more even sound across all notes.
