  Furthermore, it is also possible to change the pitch by operating the key setting switch shown in the figure, and it is possible to set the pitch information of the music to be reserved or the music to be added to the eighteenth list. The pitch information set before registration of the eighteenth list is recorded together with the eighteenth table as shown in FIG. 2, and is used when a music piece is selected using the eighteenth table.

  When reservation is designated by the user, the music identifier of the music is determined as an identifier to be transmitted to the commander 2, and the normal search process is terminated. As described above, in the present embodiment, it is possible to perform the music search by the normal search process and to create the eighteenth list. The creation of the eighteenth list is not limited to this embodiment, it may be possible to create it in an appropriate mode of the karaoke system, or user information is managed by a server arranged on the Internet, from a home PC or mobile phone etc. You may be able to register.

  As shown in the flowchart of FIG. 6, the duet mode that is the music selection method according to the embodiment of the present invention includes a music extraction process S205 and a determination process S400. FIG. 9 is a schematic diagram for explaining the outline of the music extraction process. As shown in the figure, among the registered users, A to H are logged in. Among these login users, A to D are logged in as customers (first group), and E to H are logged in as employees (second group).

  In the music extraction process, among the logged-in users, the music list of the operating user is compared with the music list of a user belonging to a group different from the operating user, and a common music identifier is extracted. In this embodiment, the eighteenth table described in FIG. 3 is adopted as the music list, and in the example shown in FIG. 9, the eighteenth table of Mr. A who is the operating user and the logged-in employee (second group) Compare with the 18th table. The music list to be compared is not limited to the eighteenth table, and a history table may be used. Further, an eighteenth table is used for the operating user, and a history table is used for the group to be compared, and the extraction target may be enlarged, or vice versa.

  In the music extraction process in the present embodiment, a duet music is extracted, and the music identifier is extracted only for the duet music. This extraction can be easily realized by referring to the genre in the music related information. Moreover, it is good also as extracting all about a music, without limiting to a duet music, or extracting about the predetermined | prescribed genre which can be choralized.

  FIG. 9 shows a case where the operation user is a customer (first group), but the operation user may be an employee (second group). FIG. 10 is a schematic diagram showing the music extraction process when the operation user is an employee. In this case, the music extraction process is performed by the operation user F's eighteenth table and the customer (second group) eighteenth. By comparing the tables, common music identifiers are extracted.

  One or a plurality of music identifiers extracted in the music extraction process are determined and confirmed by the user in the determination process, and the determined music identifier is transmitted to the commander 2 in S203. Is done. FIG. 11 is a diagram showing a performance process in the commander 2 that has received the music identifier. First, the received music identifier is sequentially registered in the reservation list. In S502, the reservation list is referred to and it is determined whether there is a music to be played next. If there is a music to be played next, the music information corresponding to the music is played in S503. At this time, when the pitch information is also specified, the performance is executed with the pitch based on the pitch information.

  In S504, the process waits for the music information performance to end. During the music performance, scoring is performed on the voice signal of the singer input from the microphone 43. When the performance is finished, the user information of the user who reserved and designated the music is updated (S505). In this embodiment, in the user information, in the history table, the music identifier, singing date, singing store, scoring information, pitch information are additionally registered for the music, and when the highest score is recorded, the scoring in the eighteenth table Information is updated. In S506, the process returns to S501 again to check the reservation list.

  Next, two embodiments in the determination process (S400) in the duet mode will be described in detail. In the music extraction process, a plurality of music identifiers may be extracted from a group different from the operating user. Here, as the determination process, a method for automatically determining the music to be played, a method for allowing the user to select, and two methods will be described. Note that the music identifier is extracted for each user in the group to be compared, and even if the music identifier is the same, if the users are different, they are treated as a plurality of music identifiers.

  FIG. 12 is a flowchart showing a determination process in the case of automatic determination. In S402a, it is determined in the music extraction process whether or not a plurality of music identifiers are extracted from different groups to be processed. If the number is not plural, that is, the number is one, the process proceeds to S405a, where the music related information of the corresponding music is displayed, and it is confirmed whether or not the operating user is allowed to play the music. FIG. 13 is a diagram showing this confirmation screen, in which a song name and a singer name are displayed as song related information. In addition to the music related information, the user name of the user having the matched music identifier on the eighteenth table is displayed as a duet partner. Furthermore, a key on the eighteenth table of the operating user is also displayed, and the user confirms that the pitch is set with this key.

  The operation user who confirms the music and duet partner and decides to duet with this music operates the reservation button on the screen to make a performance reservation for the music (S407a). On the other hand, if the music or duet partner does not like it, the return button is operated to return to the top menu (S409a).

  On the other hand, when there are a plurality of extracted music identifiers in S402a, one is selected from the music identifiers. In the present embodiment, in the eighteenth table belonging to the other group to be compared, it is compared with the scoring information of the music in the user's eighteenth table (S403a), and the one with the smallest difference in scoring information is determined as a performance candidate. Yes. Confirmation by the operating user is executed as in the case where one of the determined songs is extracted in S405a.

  In this embodiment, scoring information is used as a condition for determining one piece of music. However, in addition to this, pitch information is used as the condition, and the same or close pitch as the operation user's pitch is selected. It is good.

  A general karaoke scoring value is determined based on the volume information (volume level level) of the singing voice, the pitch information (the level of the singing key), and the like. In the case of a duet, if the keys to be sung greatly differ from each other and the key of the music is made to coincide with one of the keys, the other singer who sings together will feel uncomfortable.

  Therefore, when both pitch information and scoring information are used, scoring information is given priority, that is, due to the pitch information being extracted with the same (same key) group, and then the person with the smallest difference in scoring information. It is preferable to extract a partner.

  Next, with reference to FIGS. 14 and 15, the determination process in the case of manual determination will be described. FIG. 14 is a flowchart showing the determination process in this embodiment, and FIG. 15 is a diagram showing a screen when presenting candidates to the user. In S402b, it is determined whether there are a plurality of extracted music identifiers. If the number is one, as in the previous embodiment, the music related information and the like are displayed as shown in FIG. 13 to confirm the reservation to the user.

  On the other hand, when a plurality of music identifiers are extracted, the plurality of extracted music related information and the like are displayed to allow the user to select a music. FIG. 15 is a diagram showing this selection screen, in which the song name, singer name, duet partner, and key are displayed (S403b). Although only five songs are displayed here, if there are other candidates, the candidates can be browsed by operating the page feed button shown on the right in the figure.

  The order in which the candidates are displayed may be arbitrary, or may be displayed using the scoring information and the pitch information such that the one that matches the operating user is the head. Furthermore, it may be possible to sort by any item such as a song name, a singer name, or a duet partner. When the user selects one song from the displayed candidates (S404b), the user waits for a song to be reserved on the confirmation screen shown in FIG. 13 (S406b), and determines the reserved song (S407b).

  As described above, in the present invention, the music list of the operating user is compared with the music list of a user belonging to a group different from that of the operating user, and the common music is extracted, so that the music to be sung and duet together, and the other user Can be easily selected. In the present specification, the embodiment in which the customer and the employee are employed as the grouping of the first group and the second group has been described. However, in such an embodiment, it is suitable for a night karaoke apparatus. In addition, as the grouping of the first group and the second group, a grouping by men and women as shown in FIG. 16 may be adopted. By referring to the personal information in the user information, it is possible to easily perform grouping at the time of login and to match chorus and duet between men and women.
