In the control shown in FIG. 10, the specification (update) of the stable sound range in the SB3 and the specification (update) of the challenge sound range in the SB4 are requested by the user through the electronic sample device 28 or the like to request a recommended song. It may be executed at the time.

  FIG. 11 is a flowchart for explaining a main part of an example of the music extraction / recommendation control executed by the CPU 90 of the server 18, and is repeatedly executed at a predetermined cycle.

  First, at SC1, information such as a predetermined input operation by an input device such as the electronic quick sample device 28 or the sex, age, music selection history, store visit history, etc. of a user who is performing a karaoke performance using the karaoke device 16. Based on this, one of the stable sound range and the challenge sound range is determined as a sound range related to music extraction. Next, in SC2, it is determined whether or not the stable sound range is determined as a sound range related to music extraction in SC1. When the determination of SC2 is negative, the processing after SC6 is executed. When the determination of SC2 is affirmative, in SC3, it is associated with the user ID of the user who is the object of music recommendation. The stable sound range stored in the SNS database 108 is read out. Next, in SC4, among the many pieces of music information stored in the music database 106, one or more pieces of music information in which the sound range from the lowest sound to the highest sound is adapted to the stable sound range read in SC3 is obtained. Extracted. Next, in SC5, the music information extracted in SC4 is displayed as recommended music for the user in, for example, the electronic quick sample device 28 so that music selection input is possible, and then this routine is terminated. In SC6, it is determined whether or not the challenge sound range has been determined as a sound range related to music extraction in SC1. If the determination at SC6 is negative, the routine is terminated accordingly. If the determination at SC6 is affirmative, at SC7, the routine is associated with the user ID of the user to be recommended for music. The challenge sound range stored in the SNS database 108 is read out. Next, in SC8, among a large number of pieces of music information stored in the music database 106, one or more pieces of music information in which the sound range from the lowest sound to the highest sound matches the challenge sound range read out in SC7. Extracted. Next, in SC9, the music information extracted in SC8 is displayed as recommended music for the user, for example, on the electronic quick sample apparatus 28 so that music selection input is possible, and then this routine is terminated.

  In the above control, SA1 and SA3 are the operation of the karaoke performance control means 110, SA2 and SA4 are the operation of the sound range determination control means 112, SB1 is the operation of the sound range storage control means 114, and SB2 to SB5 are the above operations. SC1 to SC4 and SC6 to SC8 correspond to the operation of the music extraction control unit 118, and SC5 and SC9 correspond to the operation of the music recommendation control unit 120, respectively.

  According to the present embodiment, a stable sound range as the first sound range specified based on the sound range information stored in the SNS database 108 corresponding to each user, and a wider sound range than the stable sound range are supported. Because it is possible to appropriately extract music information that fits each challenge range as the second range to be played, it is possible to select a performance song that each user can sing without danger, and to sing if each user is a little impossible Appropriate music can be extracted for each scene where it is desired to select a performance music that can be challenged. That is, the karaoke system 10 that extracts appropriate music according to the scene can be provided.

  The user range specifying means 116 (SB2 to SB5), for a plurality of the range information stored in the SNS database 108 corresponding to each user, includes a range that is redundantly included in the specified range or more of the range information. Since the range is specified as the stable range, and the range included in at least one range information is specified as the challenge range, the stable range corresponding to the range that each user can sing without harm, and each user However, the challenge range corresponding to the range that can be sung can be suitably specified in a practical manner.

  The music extraction control means 118 (SC1 to SC4 and SC6 to SC8) performs the first music extraction control and the second music extraction according to the number of users who perform karaoke performance using the karaoke device 16. Since either one of the controls is selectively executed, for example, when there are a relatively large number of users performing karaoke performance together, music corresponding to the range where the singing can be performed without danger is extracted. However, if the number of users performing karaoke performance together is relatively small, it is appropriate depending on the scene, such as extracting music corresponding to the range that can be sung if you do it a little Music extraction can be realized.

  The music extraction control means 118 selectively selects one of the first music extraction control and the second music extraction control according to the sex of the user who is performing the karaoke performance using the karaoke device 16. For example, if the users who perform karaoke performance together include the opposite sex, for example, the music corresponding to the range that can be sung without harm is extracted and the performance is performed together. If all the users are the same sex, it is possible to implement appropriate music extraction according to the scene, such as extracting music corresponding to the sound range corresponding to the sound range that can be sung with a little effort.

  The music extraction control means 118 selectively selects one of the first music extraction control and the second music extraction control according to the age of the user who is performing the karaoke performance using the karaoke device 16. For example, if there is a gap in the age of users who are performing karaoke together, extract the music corresponding to the range that can be sung without harm, and perform karaoke together When the number of users who are present is the same generation, it is possible to implement appropriate music extraction according to the scene, such as extracting music corresponding to the sound range corresponding to the sound range that can be sung if a little impossible.

  The music extraction control means 118 corresponds to a user who is performing a karaoke performance using the karaoke device 16, and according to a performance history of a performance tune that has been played using the karaoke device 16 in the past. Since either one of the music extraction control and the second music extraction control is selectively executed, for example, the user's performance history of the user performing the karaoke performance using the karaoke device 16 is added to the user. If there is a lot of music that corresponds to the range that can be sung without any danger, extract the music that corresponds to the range that can be sung without any danger, and if there are a lot of music that corresponds to the range that can be sung, In such a case, music extraction corresponding to the sound range corresponding to the sound range that can be sung can be extracted with a little effort.

  The music extraction control means 118 is one of the first music extraction control and the second music extraction control according to the performance music played by each user from the start of performance to the present time in the karaoke performance by the karaoke device 16. Since one of them is selectively executed, for example, when each user selects a lot of music corresponding to the range that can be sung without any danger from the start of the performance to the present time, the range that can be sung without any danger If you select a number of songs that correspond to the range that can be sung if you try a little, you can select a song that corresponds to the range that corresponds to the range that you can sing. For example, it is possible to implement appropriate music extraction according to the scene.

  The music extraction control means 118 determines whether the plurality of users who have performed karaoke performance using the karaoke device 16 have performed karaoke performance together in the past. Since either one of the extraction control and the second music extraction control is selectively executed, for example, when users performing karaoke performance have never performed karaoke performance together in the past Extracts music that corresponds to the range that can be sung without any danger, and if you have performed karaoke together in the past, if you do not do it a little, the music that corresponds to the range that can be sung For example, it is possible to implement appropriate music extraction according to the scene.

  The music extraction control means 118 selectively executes one of the first music extraction control and the second music extraction control depending on whether or not a predetermined application is activated in the karaoke device 16. For example, when a performance evaluation application or the like is activated in the karaoke device 16, for example, a performance evaluation application or the like is extracted by extracting music corresponding to a sound range that can be sung without fail in consideration of the evaluation result. If it is not activated, an appropriate music extraction can be realized depending on the scene, such as extracting music corresponding to a sound range corresponding to a sound range that can be sung with a little effort.

  According to the present embodiment, the first range specified based on the range information stored in the SNS database 108 corresponding to each user, and the second range corresponding to a range wider than the first range. The music information that suits each can be extracted as appropriate, so it is challenging to select the performance songs that each user can sing without harm, and the performance songs that each user can sing if they try a little. Appropriate music can be extracted for each desired scene. That is, it is possible to provide the server 18 that extracts appropriate music according to the scene.
