DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument which has not only performance data but also music data corresponding to the performance data, and is capable of performing an automatic performance and displaying a music score on a display screen.

[0002]

2. Description of the Related Art In recent years, some electronic musical instruments have been configured to display a musical score on a display screen. In such an electronic musical instrument, when performing a performance practice, for example, operating a controller such as a mouse to designate a start point and an end point of a range in which a musical score on the display screen is to be practiced, There is a configuration in which a range of accompaniment is repeatedly and automatically performed, and the user can practice using the keyboard in accordance with the accompaniment. If the electronic musical instrument has a keyboard, the keyboard for performance practice may be the keyboard of the electronic musical instrument, or may be another keyboard, such as an acoustic piano.

[0003]

However, even if a score is displayed on the display screen, a beginner cannot know from where to where in the displayed score is a range of musically meaningful delimiters. There is a problem that it is difficult to specify such a musically meaningful range or a range where effective practice can be performed.

[0004] If the instruction is given appropriately ignoring the musical meaning, for example, if it is instructed to start in the middle of a bar, if the performance is repeated, the beat will not be connected, so that it is not musical and effective practice cannot be performed. Even if you select a measure, the measure break does not always correspond to a musically meaningful phrase, and it may be cut off in the middle of a musically meaningful phrase or may include extra sounds. In some cases, effective training cannot be performed.

In some cases, effective practice cannot be performed because the meaning of the music symbol on the score and the range on the score affected by the music symbol are unknown. In view of the above circumstances, it is an object of the present invention to provide an electronic musical instrument in which a range on a musical score can be easily specified.

[0006]

The electronic musical instrument of the present invention that achieves the above object includes: (1) musical score data representing a musical score, performance data representing the performance of the music indicated on the musical score, and musical performance data on the musical score. (2) display means having a display screen for displaying a musical score based on musical score data (3) automatic performance means for performing an automatic performance based on performance data (4) display screen (5) An associating means for associating a point on the display screen designated by operating the designation operator with predetermined phrase data stored in the memory. It is provided.

Here, in the first electronic musical instrument of the present invention, the display means may display the range of the phrase data corresponding to the point on the display screen designated by operating the designation operator. This is specified in the score displayed above. In the second electronic musical instrument of the present invention, the display means may display the musical score and the musical information of the phrase data corresponding to the point on the display screen designated by the operation of the designation operator. Is configured.
The musical information includes, for example, the tempo of the phrase data represented by the phrase data, a change in velocity, the length of a note and the sounding timing, the performance operation procedure of the phrase, and the like.

In the electronic musical instrument according to the present invention, the automatic performance means may be configured to selectively automatically play phrase data associated with the association means, or to selectively mute the phrase data. Constitution is also a preferred embodiment. In the fourth electronic musical instrument of the present invention, the memory stores a plurality of performance data for one phrase data, and corresponds to the phrase data associated by the association means. The automatic performance means is provided with a selection operator for selecting desired performance data from a plurality of performance data, and the automatic performance means is selected by operating the selection operator for the phrase data associated by the association means. It is configured to perform an automatic performance based on the performance data.

Here, the "plural performance data" may be separately created performance data, but for example, there is only one performance data, and the performance data is changed by changing the performance data. May have change data for generating the performance data. Such a case is also included in the "plural performance data" of the present invention.

[0010]

In the electronic musical instrument of the present invention, phrase data representing a musically meaningful range (phrase) on a musical score is stored in advance, and for example, a designating operator such as a mouse is operated to display a phrase on a display screen. When a point is specified, a phrase corresponding to the point is selected. Therefore, even a beginner can select a meaningful range on a musical score simply by designating, for example, a point to be practiced in a point manner, thereby enabling effective practice.

[0011]

Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing a hardware configuration of an electronic musical instrument according to an embodiment of the present invention. The electronic musical instrument 10 shown in FIG. 1 includes a CPU 11, and a program stored in a ROM 12 is read out to the CPU 11 via a bus 30 and executed using the RAM 13 as a work area. The electronic musical instrument 10 also includes a data memory 14 in which performance data, musical score data, and phrase data representing an area of each musically significant phrase on the musical score are stored. The stored performance data is input to the sound source 15 and converted into a tone signal, and the tone is emitted to the space via the amplifier 16 and the speaker 17. Further, the musical score data stored in the data memory 14 is transmitted to a display unit 16 such as a CRT display, and the musical score of a portion corresponding to a portion currently being automatically played is displayed on the display unit 18. In addition, a desired portion of the score can be displayed on the display section 18 by operating the keyboard 19 independently of the automatic performance. How to use the phrase data stored in the data memory 14 will be described later.

The electronic musical instrument 10 has a mouse 20. By operating the mouse 20, a point on the display screen displayed on the display unit 18 can be designated. Further, various instructions can be input to the electronic musical instrument 10 by operating the operation panel 21. The electronic musical instrument 10 is provided with a keyboard 22. Performance data generated by operating the keyboard 22 is stored in the RAM 13 and transmitted to the sound source 15 to emit musical tones by the keyboard operation. Is done.

Further, the electronic musical instrument 10 is provided with an external memory 23 detachably, and various functions are added to the electronic musical instrument 10 according to the contents of the external memory, or a new function is added to the electronic musical instrument 10. Music performance data and musical score data are input. FIG. 2 shows the electronic musical instrument 1 shown in FIG.
FIG. 5 is a diagram showing a first example of a display screen based on musical score data, displayed on a display unit 18 of No. 0.

On this display screen, a musical score and music symbols constituting the musical score are displayed, and buttons (icons) indicating points to be designated by the mouse 20 are shown. The arrow in the figure indicates the pointing mark of the mouse 20. Also, in this figure, the range of a certain phrase is indicated by a broken line in the score, which indicates that this range forms one phrase in the example here. Such a broken line does not appear on the actual display screen.

FIG. 3 is a view showing a second example of the display screen displayed on the display unit 18. As shown in FIG. First, a musical score is displayed on the display screen. When the instruction mark of the mouse 20 is moved to the position of the button and the button is designated, a list of processes below the musical score in FIG. 3 is displayed. Then, next, in the list, here, for example, by moving the instruction mark to “select a range” and designating it, the area of the phrase corresponding to the initially designated button becomes, for example, as shown in FIG. The notes are displayed in a color other than black or at a different brightness, so that the musical range of the musical sequence of the phrase can be recognized. The method of specifying the range of the phrase at this time is not limited to the above-described method, and the region of the phrase may be indicated by some kind of display.

For notes in a predetermined range (phrase),
When there are a plurality of prepared processes, a method of arranging a plurality of buttons according to the process, and arranging only one button as shown in FIG. 3 and clicking the button, a list of the above processes is displayed. Then, there is a method of selecting one of those processes. In addition, there is a method in which a button on a musical score has only a role of selecting a predetermined range (phrase), and processing is separately instructed. In that case, by providing a button on the screen for each process and clicking it,
The process may be executed, and the process may be instructed from the keyboard 19 or the operation panel 21 instead of the screen.

Even when a range on the score is designated, an appropriate point on the score is designated without providing a button (icon) on the display screen, and a phrase corresponding to the designated point is designated. May be selected. When "listen to model performance" is designated in the processing list shown in FIG. 3, the performance data of the phrase portion is transmitted from the data memory 14 to the sound source 15, and the model performance of the phrase portion is performed.

"Explanation" in the processing list shown in FIG.
If you specify, explain how to play the phrase part, for example, "Please play with your wrist soft and smooth."
Is displayed. Note that the explanation may be made by voice instead of the display or together with the display. FIG. 4 is a diagram showing a third example of the display screen.

A score is first displayed on the display screen, and a music symbol on the score is designated. Here, rit. =
When one of the symbols “temporarily slow” and a tempo = “at the original tempo” is specified, the tempo data of the corresponding range of the score (performance) data is displayed as shown below the score in FIG. You. For beginners, rit.
Such a display is effective because it is not known to what extent the symbols of “a” and “a tempo” have an effect, and how to play.

FIG. 5 is a diagram showing a fourth example of the display screen. When a crescendo on a musical score, that is, a music symbol instructing to play more and more strongly, is specified, keystroke strength is extracted and displayed from corresponding musical score (performance) data in a predetermined range. In this case as well, as in the case of the tempo, such a display is effective because a beginner does not know the range exerted by the symbol and how to play.

FIG. 6 is a diagram showing a fifth example of the display screen. As shown in FIG. 6, the length of each note constituting the designated phrase and the sounding timing may be graphically displayed. FIG. 7 is a diagram showing a sixth example of the display screen. As shown in FIG. 7, when a number of vertically arranged keyboard-like figures corresponding to the range of the musical score shown in FIG. 7 are displayed, and the corresponding notes are displayed from the top in the order of key depression, the score can be read. Even beginners who are not able to know the position to hold down, and also understand the relationship between how to hold back and forth. The fingering number may be added to the data, and the corresponding note may be displayed by a fingering number instead of a black circle.

FIG. 8 is a diagram showing a seventh example of the display screen. Store the actual performance corresponding to the range of the score as a digital moving image and play it back, or record the video from the beginning to the end of the song and correspond to the start point and end point of each phrase The time code of the video may be stored, and only that portion may be reproduced.

In this way, by showing how the predetermined range is played by the video, the difference between the video of the model performance and the situation in which the user himself is playing can be recognized, and the problem can be solved. Can be found. Also, here, a recorded actual performance may be used, but the same effect can be obtained by displaying the performance in animation.

If there is no storage capacity for storing a digital moving image, a video of a model performance is recorded on a video device, and this device and the video device are connected by a control line to correspond to a range of a musical score. The time code of the video to be recorded may be stored, and the video device may be controlled to start at the position of the time code and start, and to stop when the time code of the video device reaches the end time code.

The above are various display examples. Next, an example of an automatic performance for a user's practice will be described. FIG.
FIG. 8 is a diagram showing how to mute an automatic performance when a phrase is specified on the display screen. When practicing the corresponding range repeatedly, continuity of musical rhythm is lost if the predetermined range is repeated as it is. Therefore, if the beginning / end of the predetermined range is not on the bar line, the position of the bar line outside the region is set as a repeated portion. However, simply repeating the measure unit will cause sounds other than the corresponding phrase to sound, which can be confusing, so when listening, pronounce only a certain range and mute only a certain range when performing partial practice. And let them play.
The repetition point may be searched for and determined each time, or may be included as data from the beginning together with the processing.

FIG. 10 is a diagram showing an example of a rhythm.
For basic practice of performance in a predetermined range, a practice that is effective as performance practice in that range may be separately prepared and practiced. For example, a rhythm practice can be performed. In this case, rhythm performance data may be provided separately from the normal performance data for the model performance, and the rhythm performance data may be repeated, or the rhythm may be extracted from the original performance data. Further, for each part, the pitch may be converted to a predetermined pitch and sounded, or the timbre may be changed to a rhythm instrument.

Also, if there is a difficulty in a song that one wants to be able to play, it is difficult to perform the performance from the beginning to the end. If you do so, you may get bored and stop practicing. Therefore, by replacing the predetermined range, which is considered difficult, with data of arrangements that can be easily prepared in advance, the display of the score and the model performance can be simplified, so beginners can use the simplified score for the time being. You can practice and enjoy music. Once you can play music with a simple phrase, you can enjoy the music. If you are willing to try a difficult phrase, put it back and practice. In this way, you can practice happily.

Also, it is possible to listen to the data performance by making changes such as stronger and weaker, or to make the data playing weaker to make it easier to practice repeatedly, to change the tone within a predetermined range, or to change the tone by 12 semitones. By changing to the upper sound, the performance can be assisted during practice. When practicing, usually, the performance data displayed on the musical score is not automatically played, but only the accompanying data that accompanies it is produced. By automatically playing all the sounds and generating only the accompaniment data within a predetermined range, the effect of the practice can be enhanced. In addition, in order to notify the trigger of entering the predetermined range, only the first one or two sounds in the predetermined range may be changed to the above-described processing, for example, a tone of 12 semitones, and then muted. .

When a music symbol is specified as described below, a commentary of the symbol itself may be displayed regardless of specifying a predetermined range (corresponding to a phrase). As a method of displaying the description, for example, the characters enclosed by "" below may be displayed side by side with the symbol, or the music symbols may be replaced with the characters enclosed by "".

Legato: Performs a series of sounds "smoothly" continuously. Staccato: Performs "cut short" for each note. Atempo: Performs at "original tempo". Yes Andante: Play at a slow tempo Allegro: Play at a fast tempo Moderato: Play at a moderate tempo The predetermined range and its processing are It may be mixed in the musical score (performance) data or may be a separate table. In the case of storing the data in external data, the corresponding portion and the processing may be stored in the musical score (performance) data and stored in the work table when the data is read into the internal memory of the device.

It is also possible to insert delimiters at musically meaningful breaks in the musical score (performance) data, and to set a predetermined range between the delimiters. FIG. 11 shows the display unit 1.
8 is a diagram showing a musical score displayed on a display screen 8 and a keyboard 22 (see FIG. 1) side by side. FIG. 11 (B), (C)
When a key on the keyboard is depressed, the note symbol on the musical score corresponding to the depressed key is displayed with a different luminance or a different color (here, red).

FIG. 12 is a flowchart showing the processing. When a note event occurs due to the key being pressed, the routine shown in FIG. 12 is started. First, in step 12_1, the musical score data in the range displayed as the musical score is sequentially searched.
It is determined whether or not the input note number and the pitch of the musical score data match, and if they do not match, the process returns to step 12_1 for comparison with the next musical score data. Proceed to. Step 12_3
Then, it is determined whether the note event is note-on or note-off.
Going to _4, the corresponding note is displayed in red. If the note is off, the process proceeds to step 12_5 to return the corresponding note to black display.

Conventionally, there has been a practice in which, when a key corresponding to a note at a certain position on a displayed musical score is correctly pressed, the key at the next position is urged to be pressed.
In particular, beginners often go back and forth many times, so instead of forcibly moving one by one as in the past, the key was pressed on the displayed score as shown here Displaying the correspondence with the key is more convenient.

[0034]

As described above, in the electronic musical instrument of the present invention, a musically significant range is selected only by designating a point on the display screen, so that effective practice can be performed.
