Instrument-practicing finger expanding device capable of realizing multi-degree-of-freedom displacement

Abstract

The invention relates to a tool for expanding finger spacing for learning musical instruments, and belongs to the technical field of orthopedic tools. The invention relates to an instrument-practicingfinger expanding device, which comprises finger sleeves and telescopic rods arranged on two sides of the finger sleeves, wherein the number of the finger sleeves is at least two, and the positions and fixations of the finger sleeves are changed by means of the telescopic rods. The instrument-practicing finger expanding device has the beneficial effects of being simple in structure, capable of changing the finger-expanding spacing significantly, convenient to use, diverse in form and small in occupied space. The adjacent finger sleeves are connected and fixed by means of the telescopic rods capable of self-locking, so as to achieve the purpose of exercising the opening force of each finger span; since the connecting point of each finger sleeve is hinged with the corresponding telescopic rod, the finger sleeves can rotate around the axis of the telescopic rods, thus the function of spatial displacement can be realized, and the purpose of adjusting angles when the fingers are opened canbe achieved. The instrument-practicing finger expanding device guarantees that a practicer can consciously or unconsciously perform the finger span expanding practice in the spare time.

Description

technical field [0001] The invention relates to a finger expanding device, in particular to a tool for practicing fingerstyle musical instruments to expand the distance between fingers. Background technique [0002] When playing the piano or guitar, the hands should maintain a certain state. If any basic movement is not well practiced, it will lead to a series of problems. For example, the fingers are not in place, and the strings are not upright enough to press the strings. Be very careful before establishing the fingering for a piece of music. The influence of fingering on playing is much more important than most piano players think. [0003] Finger extension, also known as finger extension, refers to the fingering that spreads the fingers horizontally, and the sum of the two fingers to touch the key and the index between them is less than the number of intervals of the two tones to be touched. Beginners, especially adults, if they do not pay attention to cultivating the...

AI Technical Summary

Problems solved by technology

Beginners, especially adults, if they do not pay attention to cultivating the correct hand shape, to a certain extent, they will not be able to keep up with the speed of learning the piano, so that beginners will seriously affect the quality of playing due to wrong hand shape. Therefore, it is necessary to provide A finger-expanding device with relatively high flexibility, used as a tool for expanding fingers when learning a musical instrument
