Abstract: The present disclosure is related to systems and methods for assisting a user in practicing a smart musical instrument. The method includes obtaining a real-time image of the user playing the smart musical instrument. The method also includes obtaining information associated with a current key being pressed and information associated with a plurality of reference fingerings from the smart musical instrument. The method also includes displaying the real-time image in real-time. The method also includes determining whether a current fingering associated with the current key being pressed matches with a reference fingering, of the plurality of reference fingerings, associated with the current key being pressed. In response to a determination that the current fingering associated with the current key being pressed does not match the reference fingering, the method further includes generating a reminder. The method still further includes displaying the reference fingering corresponding to the current fingering.

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.
