That is, the preliminary practice mode is a mode in which only the notes on the score are played without a beat or a rhythm. A mode in which a note number is displayed on the keyboard 240 for one note or notes to be simultaneously played, And the finger numbers to be played next appear in order of the notes in order.

Thus, in the preliminary practice mode, it is possible to practice while checking one by one whether the note to be played and played by the learner on the score sheet is correct regardless of the beat.

The section exercising mode is a learning mode in which one or two notes are played back before the finger is requested to the learner and a finger number corresponding to the played note is displayed on the keyboard 240 corresponding to the beat of the note .

That is, in the interval exercise mode, the learning control unit 230 first sounds one or two words, and then displays the finger number on the keyboard 240 and repeats the interval again. It is a way to follow.

In this case, when the learning control unit 230 displays the finger number while playing it, the tempo and the note length on the score can be adjusted to the time when the display unit 242 is lit. For example, when the two notes (or the second notes) In the case of " 2 "

Accordingly, in the interval exercise mode, it is possible to assist the learners to learn the sounds learned in the above-described idle mode with an accurate tempo.

The play mode is a learning mode in which a finger number is displayed corresponding to a predetermined beat of a digital musical score to be learned on the keyboard 240 and a finger is requested to the learner from the beginning to the end of the digital musical score corresponding to the predetermined beat .

The one-handed mode is a learning mode in which the learner is requested to have a fingering by only one hand of the learner's left hand or right hand.

The accompaniment mode is a learning mode in which the musical scale corresponding to the other hand, which is not learned while the learner learns with only one hand according to the one-hand mode, is automatically played by the keyboard 240.

In one embodiment, in executing each of the above-described modes, the learner controls the learner in accordance with each learning mode, if the learner does not fingers according to the corresponding scale during learning, The progress of the scale can be stopped.

The keyboard 240 forms a piano keyboard of the piano main body 210 and reads a finger request signal transmitted from the learning control unit 230 to input a finger number to be fingered when the finger 240 corresponds to the finger fingering position, Is displayed on the display section 242 formed on the upper portion of the key body 241. [

In one embodiment, the display unit 242 may be formed as a display means such as an LCD or an LED, and is not limited to the name of a display means capable of displaying numbers by emitting light of various colors. This is possible.

That is, the display unit 242 preferably displays the finger numbers fingered with the left hand and finger numbers fingering with the right hand in different colors so that they can be easily distinguished.

For example, finger numbers fingered with the left hand are displayed in green while finger numbers fingering with the right hand are displayed in red.

However, the displayed color is not limited to the above-described green or red, as long as the color can be distinguished from the left hand and right hand finger numbers.

In playing the piano, the player moves his / her wrist according to the position of the keyboard, and fingers are individually fingered using the respective fingers. In the case of the keyboard located on the front of the user, While the wrist, the palm and the keyboard are kept in line with each other, as the player's left hand moves to the left, the left-hand neck moves gradually from the player's body toward the left, while the left- It should still be in line with the keyboard.

Accordingly, when the player's left hand moves to the keyboard located on the left, the connecting angle between the left-handed neck and the left-handed floor necessarily changes.

Therefore, the learning piano 200 having the above-described configuration guides the user to keep the palm and the keyboard horizontal regardless of the position of the user's wrist, so that the user can learn the correct fingering habit from the initial learning of the piano But it can help you to learn the balanced habits of your wrist and palm.

Fig. 4 is a view for explaining another embodiment of the keyboard of Fig. 2;

Referring to FIG. 4, the keyboard 240 according to another embodiment includes a key body 241, a display portion 242, a touch sensing portion 243, and a pressure sensing portion 244. Here, the key body 241 and the display portion 242 are the same as those in Fig. 2, and thus description thereof is omitted.

The touch sensing unit 243 is provided at an upper portion of the key body 241 corresponding to a position where the learner fingers the finger, and senses the area of the learner finger fingered to the key body 241. [

The pressure sensing unit 244 is formed at a lower portion of the touch sensing unit 243 and senses the pressure of the learner's finger fingered to the key body 241. [

However, the touch sensing unit 243 and the pressure sensing unit 244 may be formed by a single device in the case of a sensor device capable of simultaneously performing the functions of the two sensors, The touch sensing unit 243 may be provided on the upper portion of the key body 241 corresponding to the finger fingering position, and the touch sensing unit 243 may be formed on the lower portion of the pressure sensing unit 244.

The learning control unit 230 controls the touch sensing unit 243 fingered by the key body 241 when the fingering angle between the key 240 and the learner's finger in the corresponding scale is an appropriate angle according to the piano fingering method ) Can be set as the reference area.

That is, when the fingertip of the learner in the scale is larger than the reference area or does not fit the reference area, the fingertip angle of the learner's finger is determined to be inadequate.

The lower part of the front of the finger of a person forms a curved line, not a plane. The contact area between the finger and the keyboard changes according to the angle of the fingers according to the learners' fingering habits.

The learning control unit 230 may use the area of the learner's finger fingered to the key body 241 transmitted from the touch sensing unit 243 so that the contact area of the finger currently fingered by the learner becomes the reference area It can be determined that the fingertip angle of the finger is formed correctly when the contact area of the finger that the current learner is fingering exceeds or falls below the reference area.

The learning control unit 230 controls the pressure sensing unit 244 fingered to the key body 241 when the fingering pressure between the keyboard 240 and the learner's finger in the corresponding scale is an appropriate pressure according to the piano fingering method ) Can be set to the reference pressure.

That is, when the fingers of the learner in the corresponding scale exceed the reference pressure or fall short of the reference pressure, the fingertip intensity of the learner's finger is determined to be inadequate.

The emotional expression of the player according to the intensity of pressing the keys is one of the most important factors in the fingering of the piano.

However, in the learning apparatus using the existing digital piano, the learning method according to the fingering strength for the emotional expression can not be provided.

The learning control unit 230 of the present invention determines that the learner's fingering sensed by the pressure sensing unit 244 exceeds the reference pressure or does not reach the reference pressure, It can be judged that the fingering pressure is not appropriate.

In addition, the learning control unit 230 can set appropriate fingering pressures for the respective notes in the musical scale of the digital musical instrument, and can judge whether or not the learner performs playing at the appropriate fingering pressure in the musical performance.

On the basis of this, when the learner does not fingers according to the reference angle or the reference pressure, the learning control unit 230 feeds back the musical scale to the user during learning or after the learning ends, can do.

The lengths of the fingers of the players are each formed as one, and the performance style of the players also has a different style as the difference in the length of the fingers.

And, depending on the pressure of pressing the piano, the sound generated by the piano also changes in a variety of ways. What is as important as the accurate fingering of the keyboard is how much force is applied to the piano.

Therefore, the keyboard 240 according to another embodiment having the above-described configuration measures not only the accuracy of the learner's fingers but also the angle of the finger fingering the keyboard and the strength of the fingering, and provides feedback to the learner It can help learners learn customized piano playing techniques.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. You will understand.

The field of music education is one of the strong conservative stereotypes that basically require direct lectures or judgments to professional leaders.

However, it can be changed drastically through our invention, which combines stereotypes of modern technology with the fact that everyone who loves the piano must register the institute to learn the piano.
