Abstract (en)
[origin: WO2013124481A1] The invention relates to a keyboard instrument with a keyboard (12) and a sound board (10) comprising a front edge (14) which runs substantially parallel to the keyboard (12) when mounted, and comprising a first lateral edge (16a) which forms a first angle (A) with the front edge (14), and comprising a second lateral edge (18a) which forms a second angle (B) with the front edge (14). Strings are also provided which can be induced to vibrate by keys of the keyboard (12) that are assigned to each string. There is also at least one sound bridge (36) which is secured to the sound board (10) and on which the other end of the strings which faces away from the keys is supported. The first angle (A) is >90o. The sound bridge (36) extends at a right angle on the sound board (10) approximately as far as a line that runs rearwards from the intersection of the front edge (14) of the sound board (10) and the first lateral edge (16a).
