It may be specified as the user's sound range related to. That is, the range from the lowest tone to the highest tone in the range information corresponding to all the music selection histories stored in the SNS database 90 corresponding to each user is set as the user range related to the user's singing voice. It may be specified. The user sound range specifying means 92 stores the user sound range specified as described above in the SNS database 90 in association with the user ID of each user.

  The music sound range specifying means 94 specifies a music sound range corresponding to each piece of music information output by the karaoke apparatus 16. In this embodiment, the music range corresponding to the music information is a range from the lowest sound to the highest sound in a guide melody (a melody corresponding to a singing part) through the performance of one performance music corresponding to the music information. is there. That is, the musical tone range specifying means 94 preferably calculates the range from the lowest tone to the highest tone in the guide melody through the performance of one musical piece corresponding to each piece of music information output by the karaoke device 16. It is specified as the music range corresponding to the music information. The music sound range corresponding to the music information may be stored in advance as attribute information of each music.

  The key change amount calculation unit 96 calculates a key change amount required for adapting the music range specified by the music range specification unit 94 to the user range specified by the user range specification unit 92. calculate. That is, the key change amount required for adapting the music range corresponding to the predetermined music information to the user range corresponding to the predetermined user is calculated. In this embodiment, the key change amount is a change amount, that is, a shift amount of a musical piece (key), for example, “+1” is shifted to a pitch higher by a semitone, and “−1” is shifted to a pitch lower by a semitone. , “+12” corresponds to a shift to a pitch one octave higher, and “−12” corresponds to a shift to a pitch one octave lower.

  Preferably, the key change amount calculation unit 96 is configured so that the music range specified by the music range specification unit 94 is included in the user range specified by the user range specification unit 92. Calculate the required key change amount. That is, it is necessary for the music sound range corresponding to the predetermined music information to be within the user sound range corresponding to the predetermined user (not deviating from the user sound range) on either the low sound side or the high sound side. Calculate the key change amount. When there is a range deviating from the user range in the music range, the music range is included in the user range by any of the key change on the music range side and the key change on the user range side. Can be. In other words, the key change amount calculation means 96 is, in other words, a relative value between the music sound range and the user sound range that is required for the music sound range to be included in the user sound range. The key change amount (key shift amount) is calculated.

  The key change amount calculation unit 96 preferably matches the midpoint of the music range specified by the music range specification unit 94 with the midpoint of the user range specified by the user range specification unit 92. The amount of key change required for this is calculated. In the present embodiment, the midpoint of the pitch range means the midpoint in the pitch range from the highest tone to the lowest tone in that range, specifically, 1/2 of the difference between the highest tone and the lowest tone, that is (the highest tone -Lowest sound) / 2. The key change amount calculation means 96 calculates the midpoints of the music sound range corresponding to the predetermined music information and the user sound range corresponding to the predetermined user, and matches the midpoints of the music sound range and the user sound range. Therefore, a relative key change amount (key shift amount) between the music sound range and the user sound range is calculated.

  The recommended key change amount presenting means 98 presents the key change amount calculated by the key change amount calculating means 96 as a recommended key change amount. Preferably, as shown in FIGS. 6 to 9 to be described later, the recommended key corresponding to the music information is inputted before the electronic music sample device 28 inputs the music selection corresponding to the predetermined music information. The change amount is presented (displayed) on the touch panel display 30 of the electronic quick sample device 28. The recommended key change amount presenting means 98 performs the key change amount when performing an octave shift in which the music sound range and the user sound range are relatively shifted by one octave and when not considering such an octave shift. The key change amount is calculated by the calculation means 96, and the recommended key change amount is presented based on the comparison result of the key change amount in each case. Hereinafter, a specific form of such control will be described.

  When the recommended key change amount presenting means 98 performs an octave shift in which the music sound range and the user sound range are relatively shifted by one octave, the key change amount calculated by the key change amount calculating means 96 is When the octave shift is not taken into account and the key change amount is smaller than the key change amount calculated by the key change amount calculation unit 96, the key change amount calculated by the key change amount calculation unit 96 when the octave shift is performed. Presented as recommended key change amount. That is, the key change amount calculation unit 96 sets the key change amount when the octave shift is performed in which the music range and the user range are relatively shifted by one octave and when the octave shift is not performed. Calculate and present the smaller key change amount as the recommended key change amount. Preferably, the key change amount calculation unit 96 calculates the key change amount when the music sound range and the user sound range are relatively shifted by one octave and when the octave shift is not performed, respectively. The smaller key change amount is presented as the recommended key change amount.

  FIG. 5 shows a key change required for adapting the musical tone range to the user musical range when the recommended key change amount presentation means 98 performs an octave shift and when the octave shift is not performed. It is a figure explaining that quantity changes. In the example shown in FIG. 5, the user sound range of the target user is indicated by a grid-like hatching region. The musical sound range when octave shift is not performed is indicated by a hatched area with a solid line from the upper right to the lower left. The musical sound range in the case of performing an octave shift is indicated by a hatched area by a horizontal line. The musical tone range after the key change is performed in order to adapt to the user's musical range is indicated by a hatched area by a broken line from the upper left to the lower right.

  In the example shown in FIG. 5, the my sound range, that is, the user sound range is “51 to 70”, and the sound range width (sound width) is “19”. Here, consider a music A having a music sound range of “45 to 62” and a sound range width of “17”. When octave shift is not performed, a key change of “+6” is required in order to adapt the music sound range corresponding to the music A to the user sound range. On the other hand, in order to adapt the music range to the user's range after shifting the musical range to one octave higher side (that is, after changing the key of “+12”), A key change is required. The same result is obtained when the music range is adapted to the user range after the user range is shifted to the octave lower side (that is, after the key change of “−12” is performed). That is, with respect to the music A shown in FIG. 5, the music sound range is used when the music sound range and the user sound range are relatively shifted by one octave than when the octave shift is not performed. The amount of key change required to adapt to the person's range is reduced. In this case, the recommended key change amount presentation unit 98 presents the key change amount calculated by the key change amount calculation unit 96 when the octave shift is performed as the recommended key change amount.

  In the example shown in FIG. 5, a music B having a music sound range of “60 to 75” and a sound range width of “15” is considered. When octave shift is not performed, a key change of “−5” is required in order to adapt the music sound range corresponding to the music B to the user sound range. On the other hand, in order to adapt the music sound range to the user sound range after shifting the music sound range to the octave lower side (that is, after changing the key “−12”), A key change is required. The same result is obtained when the music range is adapted to the user range after the user range is shifted to the octave higher side (that is, after the key change of “+12” is performed). That is, with respect to the music B shown in FIG. 5, the music sound range is used when the music sound range and the user sound range are relatively shifted by one octave than when the octave shift is not performed. The amount of key change required to adapt to the person's range is reduced. In this case, the recommended key change amount presentation unit 98 presents the key change amount calculated by the key change amount calculation unit 96 when the octave shift is performed as the recommended key change amount.

  When the key change amount calculated by the key change amount calculating unit 96 corresponding to the musical tone range is equal to or greater than a predetermined value (for example, “± 6”), the recommended key change amount presenting unit 98 The key change amount calculated by the key change amount calculation unit 96 when the octave shift is performed in which the music range and the user range are relatively shifted by one octave is presented as a recommended key change amount. That is, when the key change amount calculated by the key change amount calculation unit 96 is not less than the predetermined value when the octave shift is not taken into consideration, the music sound range and the user sound range are relatively set to one octave. The key change amount calculated by the key change amount calculation means 96 when the octave shift is performed every time is presented as a recommended key change amount. In the example described above with reference to FIG. 5, the key change amount calculated by the key change amount calculation unit 96 is “+6” when the octave shift is not considered for the music piece A. Therefore, “−4”, which is the key change amount calculated by the key change amount calculation means 96 when the music sound range and the user sound range are relatively shifted by one octave, is presented as the recommended key change amount. . For the music B, when the octave shift is not considered, the key change amount calculated by the key change amount calculating means 96 is “−5”. Therefore, the key change amount is presented as a recommended key change amount. When the predetermined value is “± 5”, it is a key change amount calculated by the key change amount calculating means 96 when the music sound range and the user sound range are relatively shifted by one octave. +3 "is presented as the recommended key change amount.
