Description

  The present invention relates to a karaoke system in which a tempo level can be arbitrarily changed and set within a predetermined range instead of a tempo level preset for each piece of music.

  Conventionally, each piece of music played in the karaoke system has an original tempo level set, and is played at the original tempo level in the default state. Further, since there is a case where it is desired to sing at a tempo level that matches the user's preference instead of the original tempo level, the tempo level can be adjusted within a predetermined range.

  Also, for each user, a memory card that stores a favorite song and performance conditions such as the tempo level of this song is prepared, and a performance that suits the user's preference is obtained by installing this memory card. A technique for playing music under conditions is disclosed (for example, see Patent Document 1).

Japanese Patent No. 2808922

As described above, in the conventional karaoke system, an original tempo level is set for each song, and in the default state, the song is played at this original tempo level.
By the way, in the case of music played at a fast tempo level, the original tempo level can be supported from the younger generation to the middle-aged generation, but the original tempo level may not be supported as the age increases. Therefore, the conventional karaoke system has means for adjusting the tempo level, and if the tempo level is too fast for the user, the tempo level is adjusted to be slow. In addition, music with a long elapsed time from the release year to the current calendar year, that is, old music, is often sung by elderly people who know the age when the music was popular. Especially in such a case, there is a possibility that the elderly cannot cope with the original tempo level.

  However, changing the tempo level for an elderly person is troublesome, and sometimes the user continues to sing through the original tempo level. Whether or not the tempo level is too fast for the singer is a matter that becomes clear only after the performance of the music starts, and the operation for changing the tempo level is mostly performed during singing. If the tempo level is changed during the singing, not only does the person listening to the music feel unnatural, but it also impresses other users that the singer cannot follow the original tempo level.

  Thus, if the singer cannot keep up with the original tempo level, not only can the singing enjoyment be fully enjoyed, but also the singer's self-esteem may be damaged.

  The present invention has been proposed in view of the above-described circumstances, and by fully playing a song at an appropriate tempo level according to the elapsed period from the release year of the song to the current calendar year, the singing enjoyment can be fully enjoyed. The purpose is to provide a karaoke system that can be used.

The karaoke system of the present invention has the following features in order to achieve the above-described object.
That is, the karaoke system of the present invention can perform at a tempo level that is arbitrarily changed and set within a predetermined range instead of the tempo level that is preset as default for each music piece. This karaoke system is provided with a music-specific elapsed period specifying means and a tempo level setting means. The elapsed period specifying means for each song specifies the elapsed period from the release year of the song to the current calendar year, and the tempo level setting means is suitable for the elapsed period from the release year of the song to the current calendar year and the music corresponding to the elapsed period. The tempo level suitable for the specified elapsed period is changed and set as the tempo level of the music on the basis of the elapsed period corresponding tempo level setting table configured by linking the tempo level.

  Further, the karaoke system of the present invention can further include tempo level data collecting means corresponding to the elapsed period in addition to the above-described configuration. The elapsed period corresponding tempo level data collecting means collects the tempo level selected when the user sings and the elapsed period from the release year of the music to the time of singing. An elapsed period corresponding tempo level setting table is constructed based on the data collected by the elapsed period corresponding tempo level data collecting means.

  According to the karaoke system of the present invention, an elapsed period from the release year of the music to the current calendar year and a tempo level suitable for the music corresponding to the elapsed time are set in advance, and when the music is selected, from the release year of the music to the current calendar year. The tempo level corresponding to the elapsed time until is changed and set as the tempo level of the music. Therefore, since the music can be played at an appropriate tempo level according to the elapsed time from the release year of the music to the current calendar year, the joy of singing can be fully enjoyed. In addition, since the music is played at an appropriate tempo level from the beginning of the music performance, the singer can sing with confidence without giving other users a sense of incongruity.

  Also, by collecting the tempo level selected when the user sang and the elapsed period from the release year of the song to the time of singing, and configuring the tempo level setting table corresponding to the elapsed time, The relationship with the appropriate tempo level can be grasped more accurately.
