Abstract
This invention relates to an improved bridge for stringed musical instruments which bridge is shaped, for preferred embodiments, so as to provide maximum, and substantially uniform, mechanical compliance between the bridge and the soundboard of the instrument over the full frequency range of the instrument while still being wide enough at each point along its length to effectively couple the frequency of vibrations to be driven by the bridge at that point. For alternative embodiments, the shape of the bridge is altered at one or more selected points along its length, altering the mechanical compliance at these points in a predetermined manner. These variations cause the instruments to have a predetermined frequency response characteristic.
