TITLE FINGER CORRECTING DEVICE FOR KEYED INSTRUMENT}

The present invention relates to a teaching instrument for a keyboard musical instrument, and more specifically, by limiting the up and down or left and right movements of the little finger within a certain range, the grandchild, such as lifting the little finger excessively up or lying sideways when using the keyboard instrument. The present invention relates to a handwriting teaching apparatus for keyboard musical instruments that can prevent the tax from being distracted.

As the economic level of society rises, parents' interest in their children's education has increased, and in particular, as the trend deepens in the field of early education, the early stage of early education begins and its field also expands.

Early education is widely conducted in the fields of arts and physical education as well as learning areas such as Korean and English. Arts and sports can be largely divided into music, art, and physical education. Music includes mainly piano and violin lessons, and sports includes ballet, swimming, and taekwondo. Among them, piano is the most popular in early music education.

The piano can be taught from the age of 3 to 4 years old, when the ability to use chopsticks is developed. It is the best instrument for developing absolute sound. This is because violins, recorders, etc. must produce notes with strings, fingers, and breath, but pianos can hear notes that have already been made by tapping the keys. Absolute pitches are raised from the fetus and completed before the age of eight, so it is better to give music education before the age of eight.

These pianos can be studied by three to four years old, but full-scale education is appropriate around 6 years old. When learning piano at an institute, it is desirable to choose a place that draws children's musical interests through various play programs. On the other hand, when learning by private lessons, there is an advantage that intensive education is possible with one-to-one responsibility guidance, but it has the disadvantage that it is easy for a child to be bored.

On the other hand, when learning the piano for the first time, your hand posture is important, and your hands should not touch the keys, and each finger should be bent almost 90 degrees so that your fingers meet perpendicular to the keys. When the key is pressed, the force for pressing the key with each finger is equalized, so that the same size sound is generated even if the key is pressed with any finger.

By the way, if you are learning to play the piano when you are young, you have to press the keys without having enough power on your hands, so pressing the keys is powerful and the magnitude of the power of each finger is different, so the size of the sound depends on the finger pressing the keys. Is different. In particular, the little finger is weak, so when you press the key with the little finger, you can lift the little finger up and press it, or tilt the hand to the little finger to apply the force. You will press the keyboard in a large area. Using the pinky in this anomalous way disrupts the attitude of playing the piano, so teachers are wary of the child's use of this attitude, and for repeated mistakes, hands can be severely scolded or falconed. Sometimes you hit. Of course, it is important to learn the correct hand posture early on, but this may cause you to lose interest in or be afraid to play the piano, or even reluctant to learn other musical instruments or hobbies. .

Accordingly, it is necessary to find a way to ensure that the child posture is correctly learned at the early stage of learning the piano while the child does not lose interest or fear about playing the piano.

Accordingly, it is an object of the present invention to provide a hand instrument teaching apparatus for keyboard musical instruments that can be taught more easily and simply by hand teaching by limiting the movement of the little finger within a certain range.
