An improved musical instrument is disclosed. The musical instrument includes at least one key assembly and at least two sets of sensors. The sensors sense one or more attributes pertaining to a force exerted on the at least one key assembly. A control unit is provided to determine amount of force sensed by sensors based on the sensed one or more attributes, and to determine location, at which the force on the at least one key assembly is exerted based on the determined amount of force sensed by the sensors. The control unit is configured to generated signals based on the determined amount of force sensed by the sensors, and the determined location. The generated signals are associated with one or more acoustic parameters.

Different aspects of the invention implement a sensor module that can be configured as a keyboard module or as a pedal module, allowing to connect a plurality of keyboard and pedal modules to assemble a configuration to the user's liking, such as, for example, the usual configuration of an 87-key piano together with two pedals. The sensor module transmits information about detected key or pedal strokes to a computer application for playback, either aural or visual. At the same time, the sensor module allows, both in the keyboard module and pedal module configuration, to transmit the feeling of playing a real piano.

Provided is a keyboard apparatus including: a key, displaced about a key axis and having a cavity opening downward formed therein; and a guide member, having a guide inserted into the cavity of the key and guiding displacement of the key by contact between a guided surface of the key and the guide. The key includes a stopper formed within the cavity. The stopper includes a base connected to the key and extending downward, and a hook formed on a lower end side of the base and displaced in a position vertically side by side with the key axis. The guide includes a recess formed on a rear surface of the guide, and the hook is inserted into the recess. The hook is formed in a position overlapping the guided surface or a position vertically side by side with the guided surface in a left-right view of the key.

There is provided an information processing device, an information processing method, and a program that further improve skills. A load weight control unit controls generation of a load weight that becomes a load with respect to motion when a keyboard is depressed by a pianist, and a keystroke recognition unit recognizes motion of the keyboard. Then, the load weight control unit performs control of starting generation of a predetermined load weight at a timing when the keystroke recognition unit recognizes that the keyboard started to be depressed, and ending generation of the load weight at a timing when the keystroke recognition unit recognizes that the keyboard ended to be depressed and started to return. The present technology can be applied to, for example, a performance skill improvement system that evaluates and trains pianists' force sense.
