Information processing device, information processing method, storage medium, and electronic musical instrument

A method for causing an information processing device including a display to perform the following processes:

• a reception process of receiving input of performance information including pitch information,
• a first image output process of outputting on the display a first image according to the performance information received in the reception process,
• a performance determination process of determining at least any of tonality, a chord type, and a pitch name on the basis of the performance information received in the reception process,
• a performance end determination process of determining whether performance ends, and
• a second image output process of outputting on the display a second image according to a result determined in the performance determination process when the end of performance is determined in the performance end determination process.

A non-transitory computer-readable storage medium for causing an information processing device including a display to execute the following processes:

• a reception process of receiving input of performance information including pitch information,
• a first image output process of outputting on the display a first image according to the performance information received in the reception process,
• a performance determination process of determining at least any of tonality, a chord type, and a pitch name on the basis of the performance information received in the reception process,
• a performance end determination process of determining whether performance ends, and
• a second image output process of outputting on the display a second image according to a result determined in the performance determination process when the end of performance is determined in the performance end determination process.

An electronic musical instrument comprising:

• a performance operator;
• a display;
• and
• a processor performing the following processes:
• a reception process of receiving input of performance information including pitch information,
• a first image output process of outputting on the display a first image according to the performance information received in the reception process,
• a performance determination process of determining at least any of tonality, a chord type, and a pitch name on the basis of the performance information received in the reception process,
• a performance end determination process of determining whether performance ends, and
• a second image output process of outputting on the display a second image according to a result determined in the performance determination process when the end of performance is determined in the performance end determination process.
