This is internationally standardized information that indicates timbre, pitch, volume, etc. That is, this MIDI information is read out, and predetermined accompaniment music is reproduced by musical tone reproduction means such as a synthesizer via a MIDI interface.

In a karaoke device using such a musical sound information storage medium, for example, when a singer selects a desired song, the accompaniment sound is usually played back so that the singer can sing the full chorus (generally, the first to third verses) of the song. This is how it works.

In addition, recent karaoke devices are equipped with a mechanism for displaying background images in addition to karaoke accompaniment. is converted into an image signal and displayed on the display screen together with the background image.

[Problems to be Solved by the Invention] However, with musical sound reproduction devices such as the karaoke device described above, a user such as a singer can only select a desired song, and the accompaniment sound to be played or the image displayed cannot be displayed. The lyrics are played in the order in which they are stored as musical tone information, starting with the prelude, each chorus (the 6th part of the song), the interlude for each chorus, and then the postlude (in a so-called full chorus). .

Therefore, it was difficult for a singer to sing only part of the chorus because the displayed lyrics would no longer be appropriate.

However, in karaoke, popular songs are played over and over again in a short period of time, which often causes listeners to get bored, and when there are many customers, only one or two choruses are played.
You may want to end with a chorus to shorten the waiting time for other customers.

Under these circumstances, a problem has arisen in which it is desired to reproduce music in a chorus pattern desired by a singer, and to also display lyrics in accordance with the chorus pattern desired by the singer.

The present invention has been made to solve the above-mentioned problems, and its purpose is to - partially reproduce each chorus in the reproduction of a song, and - provide accompaniment without deteriorating the flow of playback of the song.
