[Industrial applications]

 The present invention relates to a self-teaching device for practicing instrumental music by recording musical tones produced by playing musical instruments and playing them back together with images.

[0002]

[Prior art]

 Conventionally, a minus one CD or record has been known as a medium for self-study of instrumental performance. This is one in which one part is recorded in the ensemble performance, and the part can be practiced by the performer during playback. However, when using this kind of media, it is necessary to practice only by hearing, and it is extremely difficult to practice when playing a solo song that does not have an accompaniment of the intro and starts solo from the first phrase or a song whose tempo changes rapidly. there were. Therefore, a device using an accompaniment video tape or the like (Japanese Patent Laid-Open No. 3-123381) has been proposed. This device pre-records and records images of the acoustics of instrumental solo performances performed by the accompaniment person and the conductor's swing of the conductor, and displays the accompaniment person and conductor on the display screen in real time. It displays the start timing and tempo at the end. In this case, the solo player can learn the timing of the beginning of the song and the change in tempo by looking at the display screen, and can practice according to the sound from the stereo speakers.

[0003]

[Problems to be solved by the device]

 By the way, the above-described conventional self-study apparatus has a problem that it lacks a sense of presence as compared with a live performance because it only reproduces sound from a speaker. Also, while simultaneously watching the image of the accompaniment or conductor displayed on the display screen and the part that displays the start timing and tempo, it is necessary to practice while turning the score as the song progresses. There was also the problem that it was difficult for a person to concentrate on the performance itself.

The present invention has been made under such a background, and reproduces a performance in a form close to a live performance, and the player does not need to turn the sheet music to practice in practice. It is an object of the present invention to provide an instrumental musical performance self-study device with an accompaniment.

[0005]

[Means for Solving the Problems]

 The apparatus according to the present invention comprises storage means for storing performance data of an automatically playing musical instrument, performance scenes of the automatically playing musical instrument, and image data representing an image of a musical score of the musical instrument to be played together with the automatic playing musical instrument, and the storing means. Control means for synchronously outputting the stored performance data and the video data to an automatic performance instrument and a video reproduction means, respectively, an automatic performance instrument for automatically performing a performance according to the performance data, and the performance scene based on the video data. And a video reproducing means for reproducing the musical score and displaying the musical score in synchronism with the musical sound produced by the automatic musical instrument.

[0006]

[Action]

 According to the above configuration, when the performer practices, the automatic performance instrument automatically performs the performance, and the image playback means reproduces the performance scene of the automatic performance instrument in synchronization with the musical sound produced by the automatic performance instrument. It The score to be played by the practitioner is also displayed on the video reproducing means in synchronization with the musical sound of the automatic musical instrument.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a case of playing a flute together with an accompaniment by a piano is shown. FIG. 1 is a block diagram showing the configuration of an instrumental music performance self-study device with an accompaniment according to the first embodiment of the present invention. In this figure, 1 is a VTR device and 2 is a video tape reproduced by the VTR device 1. The video tape 2 has one video signal channel and a plurality of audio signal channels. A video signal obtained by shooting a performance scene by a VTR is recorded in the video signal channel among these channels. Two of the audio signal channels are PCM (pulse code modulation) signal channels, and one channel of the other channels is a HIFI (high fidelity) signal channel. In the PCM signal channel (L, R), a PCM signal corresponding to a performance sound obtained by playing the flute is recorded. The playing sound of the flute is not limited to the PCM signal channel but may be recorded on the audio signal channel. The HIFI signal channel records a signal obtained by analog-modulating the MIDI signal (performance data) output from the automatic piano. The VTR device 1 reads the PCM signal recorded in the PCM signal channel (L, R), converts it into an analog audio signal, and outputs it from the L channel output terminal and the R channel output terminal. The analog modulation signal recorded on the HIFI signal channel is output from the VTR device 1 as it is after being reproduced. An amplifier 3 amplifies the PCM signal channel (L, R) received from the VTR device 1. A modulator / demodulator 4 demodulates the analog modulation signal received from the VTR device 1 into a digital MIDI signal. An automatic piano 5 receives a MIDI signal transmitted from the modulation / demodulation device 4, and performs an automatic performance by this MIDI signal. Reference numeral 6 is an L-channel speaker, and 7 is an R-channel speaker, which receives the audio signal transmitted from the amplifier 3 and produces a flute tone. A CRT (Cathode Ray Tube) 8 receives the video signal V transmitted from the VTR device 1 and reproduces the video on the screen.

Next, a system for recording a performance on the video tape 2 will be described with reference to FIG. First, the musical sound of the flute is collected by the fruit microphones 11a ₁ , ... 11a _n installed in the vicinity of the sound source of the flute and recorded by the digital multitrack recorder 12a. The musical tone signals thus recorded are recorded on the DAT (digital audio tape) 13a after undergoing a mixdown operation. The performance data of the automatic piano 14 is recorded in the FD 15 as a MIDI signal. On the other hand, the performance scene of the automatic piano 14 is simultaneously recorded by the VTR camera 16 and recorded on the video tape 17 prepared separately from the video tape 2. The recorded contents of these DATs 13a are recorded in the PCM signal channel of the video tape 2. The MIDI signal recorded on the FD 15 is reproduced from the FD 15 and analog-modulated, and recorded on the HIFI signal channel of the video tape 2. The recorded contents of the video tape 17 are recorded in the video track of the video tape 2.

When the image data of the performance scene recorded on the video tape 17 is recorded on the video tape 2, a score is input by the VTR editor 18 shown in FIG. As the VTR editing machine 18, a video title input machine or the like, which inserts a title or the like into a video image of a taken video tape by a superimposing function, can be used. For example, there is a method of inputting the musical score by reproducing the recorded video tape and superimposing it on the image as the music progresses while listening to the performance. Further, when inputting the score, editing such as changing the color of the note corresponding to the musical note as the music progresses or blinking the note may be performed.

When the video tape 2 on which the performance recording has been performed in this way is mounted on the VTR device 1 and reproduced, it is recorded on the PCM signal channels (L, R) as shown in FIG. The PCM signal of the flute sound becomes an analog signal, is output from the VTR device 1, and is transmitted to the L channel speaker 6 and the R channel speaker 7 via the amplifier 3. Then, the flute sound is emitted from the L channel speaker 6 and the R channel speaker 7. The analog modulation signal of the MIDI signal recorded on the HIFI signal channel is demodulated by the modulator / demodulator 4 into a digital MIDI signal and transmitted to the automatic piano 5. Then, the automatic piano 5 is played by this MIDI signal. On the other hand, the video signal V is transmitted to the CRT 8 and the video played by the performer of the automatic piano 14 is reproduced. At the same time, a score corresponding to the musical sound of the flute sounded from the L channel speaker 6 or the R channel speaker 7 is displayed at the edge (for example, the lower part) of the image screen of the CRT 8. Here, when the flute player practices together with the accompaniment by the automatic piano 5, the volume of the L channel speaker 6 and the R channel speaker 7 at which the flute sound is produced is reduced.

FIG. 3 is a block diagram showing the configuration of an instrumental performance self-study device with accompaniment according to the second embodiment of the present invention. The instrumental musical instrument self-learning apparatus with accompaniment shown in the figure is different from the first embodiment in that the performance data of the automatic piano 14 is not recorded from the FD 15 to the channel of the video tape 2 but is stored individually in the FD 15. . Therefore, a synchronous playback device 9 is connected between the VTR device 1 and the automatic piano 5. The VTR device 1 supplies video data to the CRT 8 and at the same time supplies a synchronous clock CK to the synchronous reproduction device 9. The synchronous reproduction device 9 sequentially reads out the MIDI signal in the FD 15 at the performance tempo corresponding to the synchronous clock CK and supplies it to the automatic piano 5. The automatic piano 5 is played by this MIDI signal.

In the above-mentioned embodiment, the case of practicing the flute with the automatic piano is shown, but the musical instrument other than the automatic piano may be a musical instrument other than the flute, such as a violin, or a combination thereof, or It is possible to have two instruments of one type. If there are a plurality of musical instruments, the PCM signal obtained by one performance is recorded on each of the PCM signal channels (L, R) of the video tape 2, and the L channel speaker 6 and the R channel speaker 7 are used. Make each one pronounced. Then, practice by reducing the volume of the speaker that produces the musical sound of the part to be practiced. Alternatively, it is possible to practice playing a piano double-shot or practice with only one hand. When practicing with only one hand, it may be possible to reproduce the image of the player's hand on the screen of the CRT8.

As described above, according to this embodiment, the following effects can be obtained. (1) Since the accompaniment by the piano is automatically performed by the automatic piano, even if there is no piano player, it is possible to practice with the accompaniment alone. (2) Since the piano sound is played back by the automatic piano, a realistic sensation of actually playing the instrument can be obtained. (3) Since the playing scene of the piano is reproduced on the screen, it becomes possible for the piano player to signal the beginning of the song. (4) Since the score to be played is displayed on the screen, it is not necessary to turn the score as the song progresses.
