  By the way, there are many karaoke songs with about 200,000 songs that have different singing timings between the first and second chorus of the song and the chorus (large chorus) located at the end of the song. To do. These are arrangements to make the music more dramatic by providing a lot of chorus, but the lyrics and melodies are often the same as No. 1 and No. 2. Therefore, the singer often mistakes the timing of singing in an attempt to sing a large chorus in exactly the same manner as the chorus No. 1 and No. 2. Specifically, if the chorus is arranged in a chorus that was not found in the chorus 1 or 2 (the intentional delay of the rhythm, which is equivalent to a rest on the score), I tend to sing earlier than the timing.

  The following music is a specific example of such music that has a lot of rust. KinKi Kids's song “Glass Boy” 's great chorus lyrics “Illuminate” has two beats between “Illuminate” and “Exit”, which was not found in No. 1 and No. 2 chorus. Mr. Children's song “Footstep-Be Strong” 's great lyric “The lonely night is coming and I hear this footstep” is “Lonely night is coming” There is a measure of one measure that was not found in No.2 and No.2 rust. Maeda Nobuteru's song “Your Only Tomorrow” 's great chorus lyrics “tears don't shed” is one bar later than No. 1 and No. 2 chorus.

  When the technique described in Patent Document 1 is used for such a problem, since singer's scoring information for each past phrase is required, it is not possible to deal with a case where there is no scoring history or a song to be sung for the first time. There is a drawback. Similarly, the technique described in Patent Document 3 must be based on the singing grading information.

  Further, when using the technique described in Patent Document 2, it is necessary to store in advance information as “a section that is easy to make a mistake” regarding music having a large chorus, and the amount of data becomes enormous. Moreover, since the singer sings earlier than the correct timing for music with great rust, the substitute singing shown in Patent Document 2 cannot be used.

  An object of the present invention is to provide a karaoke apparatus capable of visually presenting information related to a song to a singer who sings a piece of music with a lot of rust.

  In order to solve the above-mentioned problem, a karaoke apparatus according to claim 1 is a karaoke apparatus that processes music data for karaoke performance, including lyrics data, reference data, and section data related to music composition, Corresponding to the first section, specifying means for identifying the first section corresponding to the rust to be sung last and the second section corresponding to any of the rust other than the first section based on the section data Determining means for comparing reference data corresponding to the second section and determining whether or not there is a non-singing section in the first section that is not in the second section for a predetermined time or more; When the lyrics are displayed on the display unit based on the lyric data and the determination means determines that the non-singing section exists in the first section, the non-singing section is given to the singer. And a display control means for displaying the singing assist icon for informing on the display unit of the presence between 唱区.

  The communication unit 12 provides an interface for connecting the karaoke main unit 10 to a communication line via a router (not shown).

  The storage unit 13 is a large-capacity storage device that stores various data, and is, for example, a hard disk drive. In the present embodiment, the storage unit 13 includes a music data storage area 13a, a singing assist icon storage area 13b, and a video data storage area 13c.

  The music data storage area 13a is an area for storing a plurality of music data. The music data is data for performing karaoke performance by the karaoke apparatus 1. When the karaoke apparatus 1 plays music based on music data, the singer can sing karaoke.

  The music data includes MIDI data, lyrics data, reference data, and note data. MIDI data is automatic performance data (karaoke performance data) for automatically playing a sound source of an electronic musical instrument, and is composed of time-series note information. The note information is composed of various commands for controlling, for example, the timing of sound generation and mute, key pressing force, pitch, and playback pitch. The MIDI data according to the present embodiment includes section data.

  The section data is data related to the music composition. Specifically, as shown in FIG. 3, it is data in which sections such as an intro, A melody, B melody, rust (rust 1 to rust 3), and outro in a certain music X are stored in time series. The section data is set in advance for each music piece. The section data is read out along the progress of karaoke performance (progress of music). In the prior art, according to the read section data, for example, the singing scoring result can be displayed for each section, or the color tone and brightness of the lighting device can be controlled.

  The lyric data is character string data for causing the display device 30 to display the lyrics telop in the karaoke music. The lyric data is preset for each music piece.

  The reference data is data serving as a reference when scoring a karaoke song by a user, and is composed of time-series pitch information representing the pitch of a vocal. The reference data is associated with music data (section data). That is, the reference data is set for each section.

  The note data is data indicating a melody (guide melody) to be sung in accordance with the music. The note data is preset for each piece of music.

  Note that the music data used in the karaoke apparatus 1 according to the present embodiment is not stored in the music data storage area 13a but may be data obtained directly from a server (not shown).

(Software configuration)
FIG. 4 is a diagram illustrating a software configuration example of the karaoke main body 10. The karaoke main body 10 includes a specifying unit 100, a determining unit 200, a calculating unit 300, and a display control unit 400.

  The specifying unit 100, the determining unit 200, the calculating unit 300, and the display control unit 400 are realized when the CPU 11a of the control unit 11 executes an operation program stored in the memory 11b.

  Based on the section data stored in the music data storage area 13a, the specifying unit 100 includes a first section corresponding to the chorus to be sung last and a second chord corresponding to any chorus other than the first section. Identify the section.

  In the example of FIG. 3, the specifying unit 100 specifies the chorus 3 to be sung as the “first section” based on the section data of the music X, and selects chorus 1 or chorus 2 other than chorus 3. It is specified as “second section”.

  The determination means 200 compares the reference data corresponding to the first section and the reference data corresponding to the second section, and determines whether or not there is a non-singing section in the first section that is not in the second section for a predetermined time or longer. judge.

  The “no singing section” refers to a section in which singing existing only in one section is not performed (a section in which lyrics are not set) when two sections having the same lyrics data are compared. The section in which such singing is not performed corresponds to the section in which the title is set. In addition, the predetermined time for determining the non-singing section is set in advance as a threshold value. Further, the predetermined time can be changed for each music piece via the remote controller 50 or the like.

  For example, the determination unit 200 compares the reference data corresponding to the chorus 3 with the reference data corresponding to the chorus 1, and determines whether the reference data is substantially the same. When it is determined that there is a difference in the reference data, the determination unit 200 determines whether the chorus 3 has a non-singing section by determining whether the difference in the reference data is equal to or longer than a predetermined time.

  The calculation means 300 calculates the length of the non-singing section. As described above, the non-singing section is a section in which a tame is set. For example, the calculation means 300 converts the difference in the reference data into rest information, and obtains the length of the non-singing section (that is, information on how many beats are appropriate). The calculation means 300 is not an essential configuration in the present invention.

  As a specific example, the reference data describes pitch data (cent) to be sung for every minute section (about 11 msec) from the beginning of the music, and the minute section without singing is filled with 0. The determination unit 200 compares the reference data of the first section and the second section from the top, and determines a minute section in which the reference data is 0 in the first section even though the reference data exists in the second section. When such a minute section continues for a predetermined time, it is determined that this is a “no singing section” in the first section. The calculation means 300 further calculates the length of the non-singing section by continuing counting until the reference data of the first section is not zero.

  The display control means 400 performs lyrics display (lyric telop display) on the display device 30 based on the lyrics data. The display control means 400 may display a video in which the lyrics telop is superimposed on the background image.

  Moreover, the display control means 400 which concerns on this embodiment displays the singing assistance icon which alert | reports presence of a non-singing section with respect to a singer, when the determination means 200 determines with the non-singing section existing in a 1st section. 30.

  The singing assist icon is for visually informing the singer of the existence of the non-singing section (information on the tame). As described above, a plurality of singing assist icons are stored in the singing assist icon storage area 13b.

  The singing assist icon is, for example, still image data as shown in FIG. Since the singing assist icon is an icon for notifying the presence of “tame”, that is, rest information, for example, it is displayed as an icon with a rest as a motif. Fig. 5 (a) shows an icon with a quarter rest as a motif, Fig. 5 (b) shows an icon with a half rest as a motif, and Fig. 5 (c) shows an all rest as a motif. Icon. The number in each icon indicates the number of beats. For example, a singer who sees the icon in FIG. 5C can easily understand that there are four beats.

  The display control unit 400 selects an appropriate icon from a plurality of singing assist icons based on the length (number of beats) of the non-singing section calculated by the calculation unit 300 and causes the display device 30 to display the selected icon. Thus, the display control means 400 can display the length (beat number) of the non-singing section calculated by the calculation means 300 in combination with the singing assist icon.

  On the other hand, the still image data may be an icon in which an illustration and a character are combined, as shown in FIG. 5 (d) and FIG. 5 (e). In addition, it is also possible to use the singing assistance icon which does not show a beat number like the icon of FIG.5 (e).

  Alternatively, the singing assist icon may be moving image data as shown in FIG. For example, as shown in FIGS. 6A and 6B, a singing assist icon in which a still image of one frame is set for each beat can be used. The display control unit 400 can display the calculated length of the non-singing section in a countdown manner in accordance with the progress of the music by displaying these still images as animations in accordance with the progress of the music. For example, if the length of the non-singing section corresponds to one measure, the display control means 400 performs a countdown display with one beat per beat (from 3 to 0) during one measure as the music progresses. .

  Here, the example of a display of the song assistance icon in the display apparatus 30 is described. 7 to 8B are diagrams showing display screens of the display device 30. FIG. In FIG. 7 to FIG. 8B, there is a non-singing section between the lyrics “Lonely night has come” and “I hear this footstep”.

  For example, when the determination unit 200 determines that there is a non-singing section in the first section, the display control unit 400 can display a singing assist icon in the vicinity of the lyrics display corresponding to the non-singing section. In the example of FIG. 7, the display control means 400 displays a singing assist icon immediately before the lyrics “I'm listening to these footsteps”, corresponding to the non-singing section. By displaying the singing assist icon in this way, a singer who sings while watching the lyrics can easily grasp the section with the benefit. The singing assist icon may be displayed immediately after the lyrics “Lonely night has come”.

  Alternatively, the display control unit 400 can display the singing guide information and the cursor on the display device 30 based on the note data (see FIGS. 8A and 8B). The singing guide information is information for visually presenting the melody of the music to the singer by displaying a pitch bar corresponding to the note data on the display screen of the display device 30. The cursor is an icon for visually presenting the progress of music, and moves on the singing guide information as the music progresses. The display control means 400 displays the lyric display section and the pre-singing section with different lyric display colors as the music progresses (in FIG. 8A and FIG. 8B, the lyrics of the singing section are indicated by diagonal lines). Further, the display control means 400 displays the tuned section and the pre-singing section with different color bars according to the progress of the music (in FIG. 8A and FIG. 8B, the tuned section's pitch bar is indicated by diagonal lines). ).

  When the determination unit 200 determines that there is a non-singing section in the first section, the display control unit 400 displays a singing assist icon in the vicinity of the singing guide information indicating the non-singing section. In this example, in the display of the pitch bar, a singing assist icon is displayed at a position immediately before a singing section (a section in which lyrics are set) starts from a non-singing section (see FIG. 8A). Then, the display control means 400 moves the cursor on the singing guide information as the music progresses, and deletes the display of the singing assist icon when the cursor passes the non-singing section (see FIG. 8B).

  In the example of FIG. 8A and the like, when the countdown display is performed using the singing assist icon as shown in FIG. 6, the display control unit 400 switches the countdown display (switching the still image) while the cursor crosses the non-singing section. )I do.

  Further, when the determination unit 200 determines that there is no singing section in the first section, the display control unit 400 displays a singing assist icon in the vicinity of the cursor and moves the singing assist icon as the cursor moves. Is also possible. In this case, since the singing assist icon is displayed together with the cursor that the singer gazes at, the singer can more easily understand the non-singing section.

  The display of the singing assist icon is not limited to the above example, and can be displayed at an arbitrary position on the display screen of the display device 30. The display position of the singing assist icon may be set in advance in the karaoke device 1 or may be designated by the singer for each piece of music via the remote control device 50.

== About the display processing of the singing assist icon ==
Next, a specific example of the display of the singing assist icon in the karaoke apparatus 1 will be described with reference to FIG. FIG. 9 is a flowchart of display processing in the karaoke apparatus 1.

  It is assumed that a certain singer makes a singing reservation for the karaoke apparatus 1 in the order of the music A and the music B through the remote controller 50 (music reservation. Step 10).

  The specifying unit 100 reads the music data corresponding to the music A from the music data storage area 13a, and based on the data included in the music data, the first section corresponding to the chorus to be sung last and the first section The second section corresponding to the chorus other than is specified (section specification, step 11).

  The determination means 200 compares the reference data corresponding to the first section and the reference data corresponding to the second section, and determines whether or not there is a non-singing section in the first section that is not in the second section for a predetermined time or longer. Determine (determination of a non-singing section. Step 12).

  When the determination unit 200 determines that there is no non-song segment for a predetermined time or more (N in Step 13), the display control unit 400 displays only the lyrics (or displays only the lyrics and the singing guide information) (only the lyrics). Display, step 14).

  When the singing of the music A is finished, the process returns to step 11, and the specifying means 100 reads the music data corresponding to the music B reserved next from the music data storage area 13a, and based on the section data included therein. Then, the first section corresponding to the rust to be sung last and the second section corresponding to the rust other than the first section are specified (identification of the section. Step 11).

  The determination unit 200 compares the reference data corresponding to the first section of the music B with the reference data corresponding to the second section, and there is a non-singing section in the first section that is not in the second section for a predetermined time or longer. (Determination of a non-singing section. Step 12).

  When the determination means 200 determines that there is a non-singing section of a predetermined time or more (in the case of Y in step 13), the display control means 400 displays the lyrics (and the display of the singing guide information) while the large rust section is displayed. When displayed, the singing assist icon corresponding to the large rustless singing section is read from the singing assist icon storage area 13b and displayed on the display device 30 (display of the singing assist icon, step 15).

  The karaoke apparatus 1 repeats this series of processing until there is no reserved music (in the case of N in step 16).

  In this example, the singing section of the music B is determined after the singing of the music A is finished, but the non-singing section may be determined in advance when the music is reserved.

  Thus, according to the karaoke apparatus 1 according to the present embodiment, it is possible to visually present to the singer information related to the large rust that was not found in the first or second rust. Therefore, the singer can reduce singing mistakes such as singing early at the wrong timing.

  Moreover, according to the karaoke apparatus 1 which concerns on this embodiment, since the determination of a non-singing section is performed for every reserved music, it is not necessary to memorize | store the data of a non-singing section beforehand. Moreover, since it can change each time how many non-singing sections are judged to be “definite”, the display according to the preference of the singer is possible.

  Moreover, the timing of singing can be more reliably grasped by displaying the singing assist icon as a moving image.

  The above embodiment is presented as an example and does not limit the scope of the invention. The above configurations can be implemented in appropriate combination, and various omissions, replacements, and changes can be made without departing from the scope of the invention. Those embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
