摘要： A damper for a piano, which has a bifurcated damper felt of which a space between two protrusions is difficult to be narrowed. A damper head extends along three strings in a lengthwise direction thereof and is movable in directions in which the damper moves into and out of contact with the three strings. Damper felt is attached to a string-side surface of the damper head such that it extends in a lengthwise direction of the damper head, and includes two protrusions formed to protrude toward the strings in a bifurcated manner such that they can be brought into contact with the three strings in a state inserted into respective spaces therebetween. The damper felt is attached to the damper head such that deformation of the damper felt in which a space between the two protrusions is narrowed is resisted.

摘要： An electronic keyboard musical instrument includes a storage device, a musical tone generation unit, a resonating sound generation unit, and an adding unit. The musical tone generation unit reads out corresponding musical tone waveform data from the storage device according to key depression information to generate a musical tone waveform signal and a first register resonating sound waveform signal. The resonating sound generation unit receives the musical tone waveform signal to cause the resonating sound generation circuit to generate a second register resonating sound waveform signal according to damper pedal operator manipulation information and the key depression information, and outputs the second register resonating sound waveform signal. The adding unit is configured to add the musical tone waveform signal and the resonating sound waveform signal from the musical tone generation unit and the resonating sound generation unit respectively, and outputting a resulting signal.
