DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accompaniment apparatus for assisting an electronic musical instrument to be played easily in accompaniment with the accompaniment. The accompaniment device of the present invention can be incorporated in a karaoke device capable of performing musical instruments in tune with karaoke singing and accompaniment, or can be applied to, for example, a usage configuration in which an electronic piano is played in accordance with accompaniment of an automatic performance device.

[0002]

2. Description of the Related Art Conventionally, karaoke apparatuses have a karaoke accompaniment performance reproducing function and a singing lyrics display function. When performing karaoke singing with a karaoke device, the range of the singing song does not always match the vocal range of the actual singer. For this reason, the karaoke apparatus has conventionally been provided with a function of changing and specifying the pitch of the accompaniment performance in semitone units, referred to as a key control function. By using this key control function, the range of the accompaniment performance can be matched to the actual range of the singer. This is commonly referred to as tuning.

[0003] Karaoke devices have recently become very diversely used. It does not mean that the singer simply sings the lyrics, but also, for example, to play an instrument such as a piano with the singer who sings in karaoke accompaniment, or to play an instrument in time with the accompaniment performance instead of singing. I have. As described above, a use mode in which a karaoke apparatus is used to perform a musical instrument or practice a musical instrument is being developed.

When performing a musical instrument in such an application, not only the lyrics are displayed on the screen but also information for supporting the musical instrument, for example, a musical score is displayed using the same means as the lyrics. If this is the case, it will be much easier to play the instrument.

A karaoke apparatus for displaying such a performance support display together with lyrics has been proposed in, for example, Japanese Patent Application Laid-Open No. 59-110083. In this karaoke apparatus, when transposition is performed by the above-described pitch changing function, the musical score is also transposed at the same time. It is displayed.

[0006]

When transposition is performed by using the pitch change function and the musical score is transposed at the same time,
Depending on the song, the key after transposition may have a large number of sharp or flat keys, but it is often difficult to play such a musical score with a musical instrument without sufficient skill. In other words, even if the pitch of the karaoke accompaniment is matched to the singer by the key control function, the tone of the transposed song will be sharp and the number of flats will be large, and it will be difficult to play the score etc. with musical instruments Sometimes.

[0007] A similar problem occurs not only in a karaoke apparatus but also in an attempt to play an electronic musical instrument in accordance with an accompaniment sound of an automatic performance apparatus. That is, when a musical score or the like is displayed on the display device in accordance with the accompaniment sound of the automatic performance device to support the performance of the electronic musical instrument, the original musical score may be difficult for the player to play. Alternatively, since the accompaniment sound is transposed, the musical score changed with the transposition may be difficult to play.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide a method of playing an electronic musical instrument along with an accompaniment, such as when transposing a pitch of an accompaniment, and the like. The purpose of the present invention is to make it possible to use an easy-to-play support display for musical instrument performance by using an easy-to-play support display and transposing the actual performance sound in accordance with the accompaniment.

Is input to the sound device 22 and the sound device 2
2 allows the performance sound to be emitted.

The keyboard 23 has a transpose function, that is, a function of changing the correspondence between the keyboard and the pitch in semitone units. When this transpose function is used, for example, when a key of C is pressed, a pitch of C is generated. When a key of C is pressed, a pitch of D is generated. Thus, even if the performance is performed at the keyboard position in C major (C major), a sound played in D major (D major) can be generated as the actually output performance sound.

In the transpose function, a transposition amount is input by using a transpose operator provided on the keyboard 23, or in response to a control signal indicating a transposition amount sent from the CPU side. Change the correspondence between keyboard and pitch in semitone units. When transposition is performed using the transpose operator of the keyboard 23,
Data indicating the transposition amount is sent to the CPU 1 via the input / output interface 4 as a control signal.

The operation of the embodiment will now be described. First, a normal operation will be described. When music is selected by the operation unit 10, the CPU 1 causes the karaoke music reproducing device 5 to reproduce the karaoke music data of the selected music in accordance with the music selection information, and temporarily loads the data into the RAM 2. The song name / lyric information of the song data is extracted in the form of a character code, sent to the character generator 7, and a character pattern corresponding to the lyrics is generated.

On the other hand, the accompaniment code information is taken out in the form of a data code, sent to the performance support display generator 8, and a display pattern corresponding to the accompaniment code information is generated. As the display format of the display pattern, any one of the displays in FIG. 3 can be selected by the display designation function of the operation unit 10. These character patterns and display patterns are synthesized by the superimposing unit 9 and projected on the screen of the TV monitor device 21 as an image.

FIG. 4A shows an example of the display.
As shown in the figure, for example accompaniment as performance support displayed to the lyrics of "... which to spread, to the joy and global" code in the form of a code name display "D _Maj · B _m · A
₇ ... ”is displayed on the screen.

The accompaniment sound is generated by inputting accompaniment data (MIDI) extracted from the karaoke music reproducing device 5 to the audio device 22 via the input / output interface 4 and the key control section 7.

Now, the singer tried to sing karaoke, but the karaoke accompaniment has a low pitch, making it difficult to sing.
It is assumed that a karaoke accompaniment pitch is increased by three semitones using the key control function by key designation of the operation unit 10. In this case, the pitch designation data is “+3”.

Upon receiving the key change designation, the CPU 1 executes a key change process for the accompaniment code data in the music data. That is, since the pitch change amount is “+3” according to the pitch designation data, the read accompaniment chord data is changed by the pitch designation data.
In this case, the upper digit of the accompaniment code data (data code) may be set to +3. That is, as described above, the accompaniment chord is displayed in the chord name display form as “D _Maj · B _m · A _7.
If the data code is “50 _H · 21 _H · 02 _H ...”, +3 is added to the data code “5” of the upper accompaniment code “D” to “8”, and the data code of B “2” "+3 to" 5 ", and the data code" 0 "of" A "to +3 to" 3 ". Therefore, "D _Maj・ B _m・ A ₇・ ・ ・
After data code key change-"is" 80 _H · 51 _H · 3
_2H ..., Which becomes "F _{Maj .D m .C 7} ..." In code name display.

For example, as shown in FIG. 4A, when the key is D, the key signature is two sharp. (2) of FIG.
Shows a display example of the karaoke tune after the key change for three semitones as described above. As shown in the figure, the accompaniment chord is displayed in the chord name display format for the lyrics "F _Maj D _m C ₇ ...
・ ”Is displayed on the screen. In this case, the key is F and the key is one flat.

On the other hand, when the pitch is changed to the above-mentioned semitone number, 3
It is assumed that the pitch is raised by two semitones instead of the individual pitch. In this case, the pitch designation data is "+2", and when the accompaniment chord is changed in the same manner as described above, the displayed chord name becomes "E.multidot." As shown in (3) of FIG.
C ^# _m・ B7... ”, The key is E, and the key signature is four sharp, making it difficult to play on the keyboard.
Such a state in which the number of sharps / flats is large is detected by the performance support display generator 8, and the detection information is transmitted to the CPU 1. In that case, the CPU 1
Without changing the display of the code name that appears to control the performance support display generator 8 leave to keep as _{"D Maj · B m · A 7} ··· " in (1) of the original 4, the On the other hand, a control signal indicating the transposition amount whose pitch is actually changed by the key control function is transmitted to the keyboard 2 via the input / output interface 4.
Notify 3.

Upon receiving this control signal, the keyboard 23 activates the transpose function and changes the correspondence between the keyboard and the pitch by the transposition amount. Thereby, TV
Even when a keyboard performance is performed according to the chord name displayed on the screen of the monitor device 21, the generated performance sound is of a key whose pitch has been changed by the operation unit 10.

In carrying out the present invention, various modifications are possible. For example, in the above embodiment, the operation in the case of performing key control using the operation unit 10 has been described. However, as another usage mode, the performance support display of the TV monitor device 21 according to the transposition performed on the keyboard 23 side. May be changed. That is, transposition is performed on the keyboard 23 side, and the transposition amount data is input to the CPU 1. In the CPU 1, the key controller 6 transposes the karaoke accompaniment in accordance with the transposition amount, and changes the performance support display (for example, a chord name) in accordance with the transposition amount and displays it on the screen. The player of the keyboard 23 changes the transposition amount of transposition while watching the performance support display, and selects a performance support display that is easy to play.

In the above embodiment, the karaoke apparatus automatically determines whether or not the performance support display after the change by transposition is easy to play. However, the present invention is not limited to this. The user manually selects a performance support display (that is, the key of a song) that the player of the electronic musical instrument thinks is easy to play using the controls provided on the karaoke apparatus, and controls the karaoke apparatus according to the selected result. The information may be sent to the keyboard 23 to transpose the electronic musical instrument to match the selection result. In the case of karaoke, the key preferred by the singer and the key preferred by the musical instrument player may be different, which is effective in such a case. In any case, according to the present invention, even if the musical instrument performing along with the accompaniment is transposed, the pitch generated by the musical instrument and the accompaniment match, and the displayed musical score is adjusted to a key at which the musical instrument is easy to play. As a result, the singer and the performer can play each other most easily.

In the above embodiment, the case where the present invention is applied to a karaoke apparatus has been described. However, the present invention is not limited to this, and the accompaniment apparatus of the present invention is adapted to accompany an electronic musical instrument such as an electronic piano. The present invention can be implemented as an independent device as performance support means for performing. In this case, a mechanism for generating an accompaniment sound and a mechanism for generating a performance support display may be realized by a personal computer and connected to the present accompaniment device. Alternatively, the automatic performance device, the display device, and the electronic musical instrument may be connected to the accompaniment device of the present invention so that the accompaniment sound is generated by the automatic performance device and the performance support display is generated by the display device. Further, the electronic musical instrument, for example, the electronic piano itself may be configured to incorporate the automatic performance device and the display device.

In the above embodiment, when the pitch is raised by two semitones, the performance support display is displayed in the original key, and the pitch of the generated tone is changed. Instead of this, the performer may set the performance support display and the transposition amount of the musical instrument so that the performer always plays in the key C. The point is that a performance support display that is easy for the player to play should be displayed.

In the above embodiment, tuning is performed in semitone units. However, the present invention is not limited to this, and finer settings may be made. In this case, it is preferable that the tuning information is transmitted and received as specified in the MIDI standard so that the pitch of the accompaniment of karaoke and the pitch of the electronic musical instrument automatically match.

In the above embodiment, the case where the accompaniment chord is used as the performance support information has been described. In addition, various other forms of performance support information such as notes based on a normal score may be displayed on the screen. it can.

In the above embodiment, the karaoke apparatus is realized by using a microprocessor. However, the present invention is not limited to this, and can be realized by a hardware circuit without using a microprocessor.

In the above embodiment, the TV monitor 1
