A keyboard device includes a plurality of keys, and a keyboard driver configured to drive at least a part of the plurality of keys. The keyboard device is configured such that sound is generated based on a first sound-generating process in which the keyboard driver is configured to drive a key corresponding to a first pitch, upon receiving performance data including the first pitch. The keyboard device is configured such that sound is generated based on a second sound-generating process that is different from the first sound-generating process, upon receiving performance data including a second pitch that is different from the first pitch.

An information processing method implemented by a computer, the information processing method including, generating pedal data representing an operation period of a pedal that extends sound production by key depression, from playing data representing a playing content.

A sostenuto mechanism linked to a sostenuto pedal and a sostenuto rod of a keyboard instrument, and the keyboard instrument are provided. The sostenuto mechanism includes a fixed member configured to be fixed to at least one of a middle beam or a key bed of the keyboard instrument, a movable member movably supported by the fixed member, and a movement transmission. The movement transmission is configured to be interposed between the sostenuto pedal and the movable member to transmit movement of the sostenuto pedal to the movable member. The moveable member is movable relative to the fixed member to turn the sostenuto rod in response to depression of the sostenuto pedal.
