<Embodiment>
A karaoke system 1 according to the embodiment will be described with reference to FIGS.

== System ==
As shown in FIG. 1, the karaoke system 1 includes a server 2 and a karaoke device 3. The karaoke apparatus 3 is installed in each karaoke room of a karaoke store. The server 2 and the karaoke apparatus 3 can communicate with each other via a network N. The network N is, for example, a public telephone line network or an Internet line. Music data for performing karaoke is transmitted from the server 2 to the karaoke apparatus 3 and the karaoke apparatus 3 plays music, so that the singer can sing karaoke.

== Server ==
The server 2 is a computer that accumulates and manages various information on the singer, the karaoke device 3, and the like. FIG. 2 is a diagram illustrating an example of a hardware configuration of the server 2. The server 2 includes a control unit 20, a communication unit 21, and a storage unit 22.

  The control unit 20 includes a CPU and a memory (both not shown). The control unit 20 performs various controls in the server 2. The communication unit 21 provides an interface for connecting the server 2 and the karaoke device 3.

  The storage unit 22 is a large-capacity storage device that stores various data. The storage unit 22 stores a plurality of music data. The music data is data for performing a karaoke performance by the karaoke device 3. The music data is provided with a predetermined ID (music ID) for each music.

  The music data includes MIDI data, lyrics data, reference data, and the like. The MIDI data is automatic performance data (karaoke performance data) for automatically playing the sound source of the electronic musical instrument, and is composed of time-series note information.

  MIDI data includes, for example, (1) key, (2) melody configuration (mode, appearance note, feature, etc.), (3) BPM, (4) chord progression (canon progression, I-POP progression, etc.), (5) use Chord (tension chord, etc.), (6) range (lowest / highest tone, etc.), (7) music scale, (8) beat, (9) modulation (semitone up / minor third up / long second down / parallel) Key / same key tone, etc.).

  The lyrics data is character string data for causing the display device 30 to display the lyrics telop in the karaoke song. The lyrics data is set in advance for each song. The reference data is data used as a reference when scoring a karaoke song by the user, and includes time-series pitch information indicating the pitch of a vocal. Reference data is set for each singing section.

  The storage unit 22 stores the singing history registered via each karaoke device 3. The singing history is obtained by associating information (song ID) indicating a song when a certain song is sung with information (singer ID) indicating a singer. By searching the song history based on the song ID, the singer who sang the song can be specified. Conversely, by searching the singing history based on the singer ID, it is possible to specify a music group sung by the singer.

== Karaoke device ==
The karaoke apparatus 3 is an apparatus for performing karaoke music and singing singers. FIG. 3 is a diagram illustrating an example of a hardware configuration of the karaoke apparatus 3. The karaoke device 3 includes a device main body 30, a sound processing device 31, a speaker 32, a display device 33, a microphone 34, and a remote control device 35.

(Main unit)
The apparatus main body 30 performs various controls related to karaoke singing, such as performance control of karaoke songs, display control of lyrics telops and background images, and processing of singing scores based on audio signals from the microphone 34 input through the sound processing device 31. .

  FIG. 4 is a diagram illustrating an example of a hardware configuration of the apparatus main body 30. The device main body 30 includes a control unit 30a, a storage unit 30b, and a communication unit 30c. The control unit 30a includes a CPU and a memory (both are not shown). The CPU realizes various functions by executing a program stored in the memory. The determination unit 301 and the presentation unit 302 according to the present embodiment are realized by the CPU of the control unit 30a executing an operation program stored in the memory.

  The determination unit 301 determines whether or not the selected songs have a predetermined number or more of singing histories of other singers.

  For example, when the singer X selects the song A and sings, the determination unit 301 inquires of the server 2 whether the song A of another singer is stored for the song A. The server 2 searches the singing history of another singer stored in the storage unit 22 for a singing history including the song A, and transmits the singing history to the karaoke device 3. The determination unit 301 determines whether the number of singing histories received from the karaoke device 3 is equal to or more than a predetermined number. As the predetermined number, a value set in advance may be used, or may be changed each time.

  When the determination unit 301 determines that the singing histories of the other singers are smaller than the predetermined number, the presenting unit 302 presents a song corresponding to song data similar to the song data of the selected song as a recommended song.

  If the singing history of the other singers is less than the predetermined number, the other singers have not sung, or at least have sung, the selected music. Therefore, it is difficult to present a recommended song for singing based on the singing history. Therefore, the presentation unit 302 extracts music data similar to the selected music data from the karaoke music stored in the storage unit 22 of the server 2 (or the storage unit 30b of the karaoke device 3), and extracts the music data. Is presented as singing recommended music.

  As described above, there is MIDI data as music data. The MIDI data includes various information such as (1) key and (2) melody configuration. Therefore, the presentation unit 302 extracts, for example, MIDI data having the same key in the MIDI data of the selected music piece A. Then, the presenting unit 302 presents a song corresponding to the MIDI data as a recommended song for singing. In this example, MIDI data is extracted based on whether or not specific information (key) is the same. For example, MIDI data may be extracted from at least one of all pieces of information. Similar music data is data in which at least one of the information included in the MIDI data matches (all information does not match unless the music is the same).

  In addition, for example, it is considered that there are a plurality of pieces of music having the same information, such as MIDI data having only the same key. Therefore, if all the extracted songs are presented, the number of songs recommended for singing may be enormous. Therefore, when there is a plurality of pieces of MIDI data with matching information, the presenting unit 302 may present only songs corresponding to the MIDI data with the number of matching information equal to or more than a predetermined number as singing recommended songs.

  For example, the presentation unit 302 determines that the number of pieces of matching information among the pieces of information included in the MIDI data of the music piece A is five (an example of a predetermined number; for example, (1) key, (3) BPM, (4) chord progression. , (6) range, (8) time signature) or more, and it is also possible to present only songs corresponding to the MIDI data as singing recommended songs. Alternatively, the presenting unit 302 extracts one piece of MIDI data having five pieces of matching information, two pieces of three pieces of MIDI data, one piece of two pieces of MIDI data, and one piece of one piece of MIDI data. Only songs corresponding to the top three MIDI data (that is, five pieces of matching MIDI data and three pieces of MIDI data) can be presented as singing recommended songs. In this case, the predetermined number is a threshold value of “top three”.

  On the other hand, when the determination unit 301 determines that the singing history of another singer is equal to or more than a predetermined number, the presentation unit 302 sings at least one of the other songs included in the singing history of the other singer. Present it as a recommended song.

  When the singing histories of other singers are equal to or more than a predetermined number, the selected song is sung by various singers. In such a case, it is also possible to present a recommended song for singing from the singing history of another singer. Therefore, the presentation unit 302 selects at least one song from other songs included in the singing history of another singer stored in the storage unit 22 of the server 2 (or the storage unit 30b of the karaoke apparatus 3). Extract and present them as singing recommended songs.

  For example, it is assumed that the singing histories H1 to H5 of other singers including the singing history of the music A are stored in the storage unit 22. In addition, the song history H1 includes songs B, C, and D in addition to the song A, the song history H2 includes songs B, E, and F in addition to the song A, and the song A includes a song A in the song history H3. In addition, songs B, F, and G are included, the song history H4 includes songs B, C, and E in addition to song A, and the song history H5 includes songs B, E, and G in addition to song A. It is assumed that

  In this case, the presentation unit 302 extracts other songs B to G included in the singing histories H1 to H5 of the other singers, and presents at least one of the songs as a recommended song.

  In general, as the singing history of another singer increases, the number of other songs tends to increase. Therefore, if all the extracted other songs are presented, the number of songs recommended for singing may be enormous. Therefore, when the singing histories of the other singers are equal to or more than a predetermined number, the presenting unit 302 presents the songs sung more than a predetermined number of times among the other songs included in the other singers' histories as the recommended songs. It is also possible. For example, in the above example, the presentation unit 302 presents songs B and E sung three or more times (an example of a predetermined number of times) as singing recommended songs. Alternatively, the presentation unit 302 may present only songs (song B in the above example) included in all singer histories as singing recommended songs.

  Further, when the singing history of another singer is equal to or more than a predetermined number, the presenting unit 302 corresponds to song data similar to the song data of the selected song among other songs included in the singing history of another singer. The song to be played may be presented as a recommended song for singing. For example, in the above example, the presentation unit 302 compares the MIDI data of the music A and the MIDI data of the music B to G. Then, the presentation unit 302 can also present only songs that match at least one of the information included in the MIDI data as singing recommended songs.

  The presentation of the recommended song can be performed by, for example, displaying the song ID and the song name on the display of the display device 33 or the remote controller 35. At that time, "The person who sang song A also sang the following songs" (when there is more than a predetermined number of other singing histories), "This is also recommended for those who sang song A" (other (When the singing history of the song is less than a predetermined number). These messages are stored in advance in, for example, storage unit 30b.

  The storage unit 30b is a large-capacity storage device that stores various data. The storage unit 30b stores the same data as the storage unit 22 of the server 2, for example, music data, lyrics telop data, and background image data for performing a karaoke performance by the karaoke device 3. When the karaoke apparatus 3 plays music based on the music data, the singer can sing karaoke.

  The communication unit 30c provides an interface for connecting the device main body 30 and the server 2.

  The server 2 searches the singing history of another singer stored in the storage unit 22 for a singing history including the song A, and transmits the singing history to the karaoke device 3 (sending singing history, step 11).

  The determination unit 301 determines whether the number of singing histories of the other singers transmitted in step 11 is equal to or greater than a predetermined number (determining the number of singing histories; step 12).

  When there is a predetermined number or more (Y in step 13), the presentation unit 302 extracts at least one song from other songs included in the singing history of another singer and presents the song as a recommended song. (Presentation of singing recommended music based on singing history. Step 14).

  On the other hand, when the number is less than the predetermined number (in the case of N in step 13), the presentation unit 302 presents a song corresponding to song data similar to the song data of the selected song as a song recommendation song (singing recommendation based on song data). Music presentation, step 15).

  As described above, according to the karaoke system 1 according to the present embodiment, even when there is no (or little) singing history of another singer for the selected music, the music data (MIDI data) is used. , A music similar to the selected music can be extracted. That is, the karaoke system 1 according to the present embodiment can present a recommended song for singing even when a song having no other singing history is selected.
