Description
Technical field
The invention belongs to the ancillary technique fields of piano practice, more specifically, more particularly, to a kind of piano practice hand
Type correcting device.
Background technology
Piano is a kind of keyboard instrument in western classical music, and range scope is from A0（27.5Hz）To C8（4186Hz）,
Almost enumerate the whole musical sounds in Musical System.Playing for piano is completed by finger.According to the physiology and appearance of human hand and
The keyboard structure form that musical instrument makes, necessarily leads to the situation that the finger touching of needs is played in adaptation.Here it is us usually
So-called " hand-type ".There is no the posture of certain changeless hand hand-type one by one in piano performance objectively.Every-first new pleasure
Qu Douhui generates new task, and the posture of playing of opponent is influenced and required.When different pianists plays same-first melody
The posture of hand also can be various, it can be said that do not have-kind of absolute correct hand-type pattern, also without one kind one at
Constant fixation hand-type pattern is construed as correctly to adapting to any performance hand-type that musical needs.It should say.
This is the concept with fundamental significance about correct hand-type.
However, for the person that begins to learn piano, it is in the foundation phase of study piano performance, we emphasize to train very much again
Support a kind of correctly basic hand-type.This is because for adapt to fingerboard arrangement architecture and playing skill, need people hand and
Finger, which has-kind is conducive to, plays action and the correct status of utilization with the transmission of playing power.This state will best suit human body
Natural growing way and finger movement physiological function.Then, the state of playing of such a hand is called basic hand-type by we.
For basic hand-type, teacher generally can have detailed explanation during giving lessons, and still, student is alone after class
When practice, lack a kind of equipment of energy correcting hand-type, beginner often forms the hand of mistake during practicing after class
Type indisposition is unfavorable for the foundation of the basic hand-type of beginner, influences subsequent study and raising process.
In order to make beginner grasp correct playing skill in the practice of piano, the practice mode to correct a mistake is existing
The auxiliary device of piano practice has following several in technology：
Chinese patent application 201521139693.9 discloses a kind of piano practice auxiliary device, as shown in Figure 1 comprising outer
Shell, enclosure are provided with phonographic recorder, central processing unit, human-computer interaction module and memory；Phonographic recorder connects with central processing unit
It connecing, recording is played when for practicing piano practice person；Memory is connect with central processing unit, for storing digital and electronic
Music score；Central processing unit, the digital and electronic music score for will be stored in the recording of phonographic recorder and memory compare, and are tied comparing
Fruit is sent to human-computer interaction module；Human-computer interaction module is connect with central processing unit, for showing comparison result.A kind of steel
Qin exercise assist can carry out auxiliary direction to piano practice person.But the piano practice auxiliary device is mainly to white silk
The piano playing sound of habit person carries out practice auxiliary, cannot play gesture to the mistake of practitioner and correct.
Chinese patent application 201610569175.3 discloses a kind of piano practice finger rectification device, as shown in Fig. 2, it is wrapped
Include finger ring set, pressing plate cutting ferrule and finger pressing plate；Finger ring set top is provided with pressing plate cutting ferrule, and pressure board set is provided with card slot,
Finger pressing plate is plugged in the card slot of pressing plate cutting ferrule.The piano practice finger rectification device finger ring position size can be according to finger thickness
Adjust, pressing plate can flexibly dismounting and change so as to same finger match.But the piano practice finger rectification device cannot be normal to beginner
Existing folding refers to, thumb from key, stick up that wrist, thumb gripping finger, little finger of toe lie low, metacarpal joint collapses and palm is tilted to little finger etc.
Mistake hand-type is corrected, it is difficult to which piano beginner is made to form the good practice played custom, be unfavorable for piano.
Invention content
The purpose of the present invention is to solve disadvantages existing in the prior art, provide a kind of piano practice hand-type auxiliary
Apparatus for correcting can help student to adapt to finger tip and stand, avoid the occurrence of that folding refers to；Contact of the thumb with key is detected,
It prevents thumb from key, enhances relaxation and the degree of flexibility of wrist, the generation of wrist phenomenon is stuck up in control；Tiger's jaw distance is limited, is slowed down
Thumb gripping finger enhances small articulations digitorum manus load-bearing capacity, little finger of toe is avoided to lie low, and increases the standing dynamics of thumb, prevents metacarpal joint from collapsing；
Palm is controlled simultaneously to tilt gently towards thumb direction, provides little finger of toe enough activity spaces, and palm is avoided to be tilted to little finger, with
The technical issues of solving to mention in above-mentioned background.
To achieve the goals above, the present invention provides the following technical solutions：
