The 32nd note is placed at the 7th white key 7 ₅₂ , the 8th note is placed at the _55th black key 7 ₅₅ , and the 4th note is placed at the _61st white key 7 _61.
Each quarter note is displayed. In addition, at the bottom of the note display, the finger number display for fingering (1: thumb, 2: index finger, 3: middle finger, 4: ring finger, 5: little finger) is performed, and in this case, the finger number 1 to be pressed. 2 and 5 are displayed as blinking keys,
A non-depressed key is displayed so that the fingers can be placed at a position suitable for depressing the next key to be depressed. In FIG. 3, the non-key depression portions are displayed so that the middle finger and the ring finger are arranged on the white key 7 ₅₉ and the black key 7 ₆₀ , respectively. In the present embodiment, the key-pressed display and the non-key-pressed display are distinguished by blinking the light.
In addition to this, the display method is not limited as long as it is a display method that can be identified, such as the intensity of light and color classification described later.

Further, a rectangular movable display frame 8 representing a movable display as a fingering range is lit around the note display.
The player recognizes this position as the position of the hand (in this case, the right hand), and moves the position of the hand as the movable display frame 8 moves. It should be noted that if the next key-depression portion is within the movable display frame 8 that has been depressed immediately before, the movable display frame 8 does not move.

Further, on the upper part of the movable display frame 8, various music signs necessary for performance, such as a dynamics symbol 9, a speed symbol 10 and an idea symbol 11, which are stored in the music data of the music storage unit 1, are displayed.

According to the guidance screen displayed on the dot matrix display 2 as described above, the performer can play the corresponding keys 7 ₅₂ , 7 ₅₅ , 7 _61.

The dot matrix control section 3 detects this key depression operation by the keystroke detection section 4, and the corresponding note from the position where the key is depressed or in the vicinity thereof to each key of the player who should press the key next. Also, the finger number is moved dot by dot, and corresponding various music signs are also displayed. At this time, if the hand should be moved to the right or left, the movable display frame 8 is also moved to instruct the movement of the player's hand.

On the other hand, the music performance data detected by the keystroke detection unit 4 is sent to the performance state determination unit 5 and compared here with the music data read from the music storage unit 1, and the determination result is, for example, "play more slowly. The message 12 such as "is displayed as the music progresses. The above guide display is repeated to guide the performer to the end of the music.

Finally, the performance state determination unit 5 performs a comprehensive evaluation until the end of the performance, sends the result to the dot matrix control unit 3, and displays the result such as "please practice more 50 points".

In the present embodiment, the case where a single-color LED is used for the lighting display is shown, but it is also possible to arrange the LEDs that emit red, green, etc. in combination, and guide the player by effectively utilizing the colors. . For example, only the inside of the movable display frame 8 is displayed in the background, and the color tone is changed depending on the state of the idea symbol or the like. As an example of this, the expression symbol is "LAMENTABILE
In the case of (sad), blue is used as the image color, and when "sad" is weak, light blue is emitted, and when strong, light is emitted in dark blue, so that the performer can also image in color.

<Effect> In the method for guiding a player of a keyboard instrument according to the present invention, the dot matrix display means and the dot matrix control unit display a key depression of a note or the like at a position corresponding to the key, and the player's key depression operation is performed. After the detection by the detection means, the note can be sequentially moved and displayed to the key position where the player should press the next key. Further, when the above-mentioned key-depression display is depressed, the non-key-depression display is performed so that the remaining fingers which are not key-depressed are arranged at the positions most suitable for the next key-depression. After the detection by the means, the player is guided by performing dot matrix display so that the player prepares his / her fingers suitable for the next key position to be depressed.

In addition to these key-depression display and non-key-depression display, the movable display frame that moves the hand itself to the left and right separately from the fingers is sequentially moved to the next key-press position in dot matrix display, so that only the fingers can be used. Instead, the right and left hands can be smoothly guided left and right.

Therefore, the fingering method is particularly important when practicing keyboard instruments, especially the piano, but the performer learns this fingering method by moving the fingers and hands sequentially with the movement of the notes. You can gradually play a good keyboard instrument.

Furthermore, by using the dot matrix display means, by displaying not only the musical notes but also various music markers, the following effects that cannot be obtained in the conventional performance guidance can be obtained.

In addition to indicating the strength of key depression to the player by displaying the shape of notes in large or small size, rest marks and dynamic marks (f, mf, mp,
Various musical signs such as p), speed signs, fermata, etc. can be displayed, and the score at the time of performance can be checked at a glance, and the image of the music is enhanced, so that the player's practice effect can be enhanced more smoothly.

Also, for dot matrix display, it is possible to give an instruction to "trill" by rotating, for example, an eighth note, and smooth movement of the right and left hands, as well as the left and right hands. Crossovers can also be displayed.

Furthermore, the dot matrix display can be used to change the background color of the display of notes and the like to display emotional expressions such as "LAMENTABILE" and images such as landscapes that match the song.

On the other hand, in addition to the above effects, the playing state determination means
Without stopping the performance, not only the pitch, but the strength of the sound,
Since it is possible to judge at any time whether the length, slur, staccato, tenuto, etc. are being played correctly, it is possible to automatically teach higher musical instrument performance.
