Musical performance evaluation system and method

A musical performance evaluation method, comprising:

• authenticating a student user accessing a client application from a client computing device in communication with a server;
• in response to a command from the client computing device, transmitting a composition data structure representing a requested musical composition to the client computing device for evaluation of a performance of the requested musical composition;
• in response to a command from the client computing device, displaying a representation of a musical encoding of the composition data structure on a composition musical notation display, which may be scrolled such that the composition musical notation display encloses a segment along the representation of the musical encoding;
• storing an intended note frequency and an expected note length value corresponding to each note of the musical encoding;
• tracking a next note for performance variable, a performance pitch score variable, and a performance rhythm score variable;
• receiving audio input through a microphone in communication with the client computing device;
• identifying a played note from the audio input by correlating the audio input to the next note for performance;
• determine a factor for deducting from a performance pitch score based on the frequency of a played note not matching an intended frequency of the played note;
• determining a factor for deducting from a performance rhythm score based on a played note being off-rhythm in relation to other played notes, and determining a factor for deducting from a performance rhythm score based on unintended changes in tempo throughout the student user's performance;
• determining whether to advance the next note for performance based on whether the frequency of a played note matches an intended frequency of the played note;
• and
• calculating final values for the performance pitch score and the performance rhythm score.
