Abstract: A floating bridge for string instruments arranged to generate a higher volume of responsive resonated sound, the floating bridge being mounted to a thin flexible wall of the instrument's resonant body, and the wall defining a flexible diaphragm. The bridge is secured to the associated strings and includes a bridge block having a clamping bar to hold each string in a fixed juxtaposed relation to the others, whereby the vibration of each string is transferred through the bridge and bridge-supporting post, or posts, so that the bridge is not subjected to the longitudinal tension of the strings, allowing the resultant vibrations therefrom to propagate to the hollow body of the instrument, without obstruction thereto.
