Information processing system, electronic musical instrument, information processing method, and machine learning system

An electronic musical instrument comprising:

• a playing device for input operation of a musical instrument by a user;
• at least one memory that stores a program;
• and
• at least one processor that executes the program to:
• acquire, from the playing device, user playing data indicative of playing of a piece of music by the user;
• generate habit data indicative of a playing habit of the user in playing the piece of music on the musical instrument, by inputting the acquired user playing data into at least one first trained model that learns a relationship between:
• player playing training data indicative of playing of a piece of reference music by a player;
• and
• corresponding habit training data indicative of a playing habit of the player in playing the piece of reference music on a musical instrument, the playing habit being indicated by the player playing training data;
• identify a practice phrase based on the generated habit data;
• and
• present the identified practice phrase to the user.

A computer-implemented information processing method comprising:

• acquiring user playing data indicative of playing of a piece of music by a user;
• generating habit data indicative of a playing habit of the user in playing the piece of music on a musical instrument, by inputting the acquired user playing data into at least one first trained model that learns a relationship between:
• player playing training data indicative of playing of a piece of reference music by a player;
• and
• corresponding training habit data indicative of a playing habit of the user in playing the piece of music on a musical instrument, the playing habit being indicated by the player playing training data;
• and
• identifying a practice phrase based on the generated habit data.

A machine learning system comprising:

• at least one memory that stores a program;
• and
• at least one processor that executes the program to:
• acquire first training data that includes:
• player playing training data indicative of playing of a piece of reference music by a player;
• and
• corresponding habit training data indicative of a playing habit of the player in playing the piece of reference music on a musical instrument, the playing habit being indicated by the player playing training data;
• and
• establish, using machine learning with the first training data, at least one first trained model that learns a relationship between the player playing training data and the habit training data.
