Description

Piano teaching auxiliary device

Technical Field

The utility model relates to a piano auxiliary exercise technical field, in particular to piano teaching auxiliary device.

Background

The piano is a keyboard instrument in Western classical music and is called as the king of the instrument; the piano music box is composed of 88 keys and a metal string soundboard, people continuously realize the importance of music along with the continuous promotion of people's material life, and meanwhile, the number of people learning music is continuously increased, especially the number of people learning a piano is continuously promoted, so that the demand on piano teaching is also increasing.

However, in the piano teaching, it is often difficult for a beginner to grasp the positions of the specific piano keys corresponding to the notes, and in addition, it is also difficult to grasp the pressing rhythms of the keys corresponding to the notes in time during the playing of a tune, so that the temperament of the played tune is not standard enough, and for the beginner, strong finger power is required for the exercise to support the beginner to continue the exercise, but obviously, the beginner does not have the finger power strength.

Although a lot of finger strength training ware and metronome have appeared on the market, these things still are independent utility, can't really combine with piano itself, let the student be not enough to the familiarity degree of piano, lead to teaching and the in-service use effect not good, mr can not supervise student's exercise constantly again, and mr just teaches student's music theory knowledge and guide how to use the musical instrument, more still need student oneself to exercise, but does not have a teaching auxiliary device to guide the student and strengthen the study to the piano.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a piano teaching auxiliary device can not only help the beginner correctly and the quick position of grasping each note place button, still combines beat training and finger dynamics training and piano itself, can train the student to the assurance of rhythm, can also press the dynamics of button according to different periods training to reach the purpose of supplementary teaching, improve learning efficiency.
