Description

Hand-type correction device for piano practice

Technical Field

The utility model relates to a music teaching technical field, concretely relates to hand type correcting device is used in piano exercise.

Background

The piano is a keyboard instrument from western and foreign classical instruments and consists of 88 keys and metal string soundboards, players drive small wooden hammers covered with felts in the piano by pressing the keys on the keyboard and then knock steel wire strings to produce sound, and the piano is praised as the king of the instrument due to the beautiful tone quality, is popular among people at present, and is one of popular instruments, and more people are learning the piano. In the process of piano practice, the correct piano hand shape is an important part of piano practice, in piano playing, fingers depend on playing force, the fingers are naturally bent during playing, and form a semicircle shape together with a palm, the semicircle shape is a hollow ball-holding shape, if the hand shapes are not right, the smoothness and fluency of piano playing can be greatly influenced, and therefore, the teaching about the hand shape in piano playing is particularly important.

In piano practice, for a beginner, no matter a child or an adult, the phenomena of unconsciously moving down of arms or wrists, retraction, piano surface pressing, finger collapsing, wrist collapsing, finger picking and the like often occur, which are all wrong actions when the piano is played, and are extremely unfavorable for people to exercise the piano, so that the exercise of the hand type control capability is needed, but the exercise of the hand type control capability is a boring process, the exercise of the hand type control capability excessively emphasizes the hand type to lead the exerciser to be tired of exercising the piano, but if the exercise of the hand type is not emphasized, the exerciser cannot master the correct hand type, and the piano playing is influenced in the future. At present, people mainly carry out the hand type correction through auxiliary assembly, comparatively common hand type unscrambler includes the horizontal pole of two fastener and fastener tops that can block on the piano, set up the hand rest on the horizontal pole, the drawback of this kind of unscrambler lies in that the guide rail is fixed, the moving range of hand rest is limited, this makes the correction effect of current unscrambler not good, in addition, current unscrambler mostly needs to block on the piano, but the piano preparation is exquisite, and is high in price, the use of unscrambler can cause wearing and tearing to the piano musical instrument body, influence the whole outward appearance of piano. Therefore, the hand-shaped correcting device for piano practice, which does not damage the piano body, is convenient to use and has a good correcting effect, is objectively needed to be researched and developed.
