The invention relates to a guitar body comprising an upper bout region and a lower bout region with a waist region disposed there between. A first and second peripheral edge of the guitar body is defined in a longitudinal direction thereof by a first and second upper bout region, a first and second waist region, and a first and second lower bout region, respectively. An anterior face and a posterior face of the guitar body extend between the first and second peripheral edges. At least one of the anterior face and the posterior face includes at least one curve so that at least a portion of the first peripheral edge includes at least one curve so that at least a portion of the first peripheral edge of the guitar body is not co-planar with at least a portion of the second peripheral edge of the guitar body.
