Abstract
A bridge for a stringed musical instrument comprises a thin wooden body having a bottom base portion adapted to be supported upon a resonant body member of the instrument and a top crown portion that is formed with grooves for holding individual strings. The base and crown portions have opposed edges that are generally parallel with respect to each other. The crown is formed with baffle slits located adjacent the grooves that are oriented obliquely with respect to the crown edge for redirecting sound waves emitting from strings back to the grooves to produce a ringing tonal effect or to the base to reduce sound attenuation within the bridge.
