Electronic musical instrument, method of controlling electronic musical instrument, and recording medium

Abstract

The invention relates to an electronic musical instrument, a method of controlling the electronic musical instrument, and a recording medium. An electronic musical instrument allows a player to operate operators as least number of times as possible to play music, and the player can play music easily and agreeably, using the instrument. Every measure decided by plural beats counted based on a designated meter a prior tone is determined from among automatic playing music data. The prior tone is a musical tone which is made note-on for example at a timing of a downbeat in the measure. If a candidate for the prior tone is one of chord composing tones, and the one of chord composing tones can compose a melody, then such musical tone is decided as the prior tone. The prior tones successively decided from the beginning of the automatic playing music data are indicated to the player as lighted up keys. The player operates the lighted up keys successively to perform the automatic playing musicdata.

Description

[0001] Reference to related applications [0002] This application claims priority based on Japanese Patent Application Japanese Patent Application No. 2017-058581 filed on March 24, 2017, and all the contents of this basic application are incorporated into this application. Technical field [0003] The present invention relates to an electronic musical instrument, a control method of the electronic musical instrument, and a recording medium. Background technique [0004] An electronic musical instrument equipped with an optical keyboard is known, and the keys to be played on the keyboard are illuminated in synchronization with automatic performance, so that the player can make progress in music performance. [0005] In order to make it easy for even beginners to perform such an instrument performance lesson, the following optical keyboard instrument technology is known in the past: as long as the timing of pressing the keys on the keyboard coincides with the output timing of the reco...

Problems solved by technology

[0007] However, the conventional technology of an optical keyboard instrument in which the melody is reproduced no matter which key is pressed as long as the timing is matched may be too simple for some users.

[0008] In addition, in the prior art of optical keyboard instruments in which the melody is reproduced when all the illuminated keys corresponding to the melody to be pressed are pressed correctly, it may be too difficult for some users.
