Abstract: An ergonomic guitar strap which reduces the load on the shoulder, balances the weight of the guitar front-to-back, absorbs shock during play and isolates motion by the use of a cushioning pad that is constructed with a soft, flexible foam layer which conforms to a user's shoulder under the load of the guitar. Attached to the cushioning pad is an internal layer of elastic webbing which stretches over the cushioning pad. In use, under the load of a guitar, this elastic layer absorbs shock, transfers the load of the guitar over the area of the pad and further isolates the motion of the guitar and contributes to the stability of the support pad on the shoulder and the stability of the guitar as it is played.
