Abstract
Abstract Disclosed is a musical instrument bridge for supporting a set of strings above a front face of a musical instrument. The bridge comprises a plate, a mounting block, and a plurality of fingers. The plate is attachable to a rear face of the instrument. The plurality of fingers are attached to the plate and extend towards a front face of the instrument. Each finger has a resonant frequency that is related to a predetermined pitch of the string supported by the finger. Each finger is designed to vibrate in a plane that is parallel to the front face of the instrument but to reduce vibration in a plane perpendicular to the front face of the instrument.
