When the finger joints touch the string, there is a movement of bending into the palm, forming a state of "tightening" and "bending" of the fingers. Generally, we call it "folded fingers".

There are two main reasons for the "folded finger" problem:

First, because the hand is too loose, the fingers stretch out, which will cause the problem of "folding fingers" of the finger joints when touching the strings. The main reason is that the player's spirit is too loose and lazy.

Another reason is that because the string is dropped too hard, and the string is not relaxed in time after the string is dropped, the fingers "pick the string" and form a "folded finger". The main reason for this problem is that the player exerts too much force. On the one hand, it is the impatient mentality of the performer, and on the other hand, it is caused by the wrong understanding of the playing strength.

Solutions and effects:

The solution to the problem of "folding the fingers" is relatively simple. First, the problem of the student's hand shape must be solved. After the string is dropped, it should be relaxed in time so as not to cause the fingers to "pull the string", so that the problem of finger extension will not occur. In this way, when the natural hand shape is considered, the fingers are perpendicular to the strings, so that "falling the strings" will not produce the phenomenon of "folding fingers".

For strength issues, first use slow exercises to calm the students' emotions and achieve the effect of "mindfulness", and then practice the movements of raising and lowering fingers and hands evenly, which is the standard practice of movements mentioned in the teaching method.

Coordinated training methods: On the basis of the above adjustments, meet certain finger requirements. First, whether staccato or legato, the fingertips must be kept perpendicular to the strings. Second, pay attention to sit upright and keep your wrists flat.
