An Improved Body Shape Definition for Acoustic Guitars

Abstract

Modern guitar design and manufacturing processes require a robust mathematical description of body shapes. Conventional curve fits such as those offered in commercial software are not possible because the shape of guitar bodies creates mathematical problems. An attractive solution is to select a reference point on the centerline of the guitar and do the curve fit in polar coordinates. This solves the mathematical problems and can give a closed form expression to become the basis of a family of body shapes.
