ABSTRACT:
The hollow body of a guitar has two discrete zones for openings in the sound board, such openings being located on either side of the longitudinal center line defined by the neck and fret board. These openings are located adjacent the periphery of the upper or smaller bout, that is above the waist. The lower bout is slightly larger than the upper bout and is provided with a bridge located below the waist. The tension forces in the strings are reacted through a central portion of the bout in the region where the single conventional sound opening is normally provided. This construction allows for a thinner sound board than has been possible heretofore, which sound board can also be braced by longitudinally extending ribs located below the strings, and can be more conveniently braced to improve its acoustic response.
