摘要： The present invention relates to a piano or a grand piano with a resonance board and strings which rest on a sound bridge with two longitudinal faces. Such a sound bridge serves to transmit vibration energy which is output by the strings of the instrument to a resonance board. The invention is based on the realization that, on the one hand, the rigidity of the sound bridge must be maintained at the locations at which it is in contact with the strings and the resonance board. On the other hand, it is advantageous if the mass of the sound bridge is reduced. For this reason, according to the invention it is proposed that the sound bridge have a first cutout and a second cutout, wherein the two cutouts are arranged on the two longitudinal edges of the sound bridge which lie opposite one another.

摘要： The Invention relates to a keyboard instrument with a keyboard and a sound board including a front edge which runs substantially parallel to the keyboard. The sound board further includes a first lateral edge which forms a first angle (A) with the front edge, and a second lateral edge which forms a second angle (B) with the front edge. Strings are provided which are induced to vibrate by respective keys of the keyboard. There is also at least one sound bridge which is secured to the sound board and on which the other end of the strings which faces away from the keys is supported. The first angle (A) is >90°. The sound bridge extends at a right angle on the sound board approximately as far as a line that runs rearwards from the intersection of the front edge of the sound board and the first lateral edge.
