Abstract: The present disclosure relates to a piano-action. The piano-action may comprises a first moving component including a concavity structure, a second moving component including a convexity structure, wherein the convexity structure and the concavity structure are configured to match each other and capable of being clipped together, and a third moving component being thin and flexible and configured to fixedly fit between the first moving component and the second moving component when the convexity structure of the second moving component is clipped into the concavity structure of the first moving component.

Abstract: A method for generating a music file for recording user performance may include: detecting, by a sensor, an event indicating a status change of an execution device of the keyboard instrument; generating, by the sensor, a signal corresponding to the detected event; receiving, by a processor, the signal; and generating, by the processor, a music file based on the signal. In some embodiments, the execution device may include a weight lever. The weight lever may a concrete structure in the keyboard instrument to simulate a rebound force generated by hammer striking on string, by striking on an elastic structure. In some embodiments, a rebound force for a first weight lever may be different from a rebound force for a second weight lever by adjusting parameters of the elastic structure or the weight lever.

Abstract: Systems and methods for providing a piano system are provided. In some embodiments, the methods include receiving a plurality of key signals related to a first performance of a piece of music, wherein each of the plurality of key signals corresponds to motion of at least one key of a piano during the first performance; generating first performance information based on the plurality of key signals; receiving musical data related to a second performance of the piece of music; receiving musical data related to a second performance of the piece of music, generating second performance information based on the musical data; and providing content for presentation on a display device based on the first performance information and the second performance information. The methods can also include receiving at least one pedal signal corresponding to motion of a pedal of the piano during the first performance, and generating first performance information based on the pedal signal.
