Abstract
The replacement of the bass-bar which is traditionally installed on the underside of the top-plate of a cello or double-bass and substituting a more elastic suspension system of radiating bars. In one arrangement, the bass-bar is replaced by a short support-bar located under the bass-foot of the bridge and has an arch cut at its midpoint in alignment with the bridge and a set of four fan-braces radiate outward at an angle to the alignment axis of the support-bar and are firmly glued to the sides of the support-bar with the fan-braces distributing the static load borne by the support-bar over the whole area of the top-plate. In another arrangement, the traditional bass-bar is replaced by a pair of tapered vibration-bars which cross in an integrally glued cross-lap joint with the region of crossing being provided with a slight arch-cut profile with the load from the X-brace region thus being spread over the entire top-plate of the instrument.
