The fingering marks on the music score are determined for the convenience of playing, except for a few marked by composers, most of them are marked by later generations. Different versions of the same piece of music have different fingering marks. Some requirements are strict, for example, some etudes are set by the author to train the flexibility of a finger, so these should be played in strict accordance with the fingering marks. But the fingering in music is generally not too strict, and it can be decided according to everyone's habits. But beginners still have to play according to the music score or the fingering given by the teacher.
Seven principles of fingering distribution
1, keep your fingers as close as possible.
2. In the hand grasping method, the finger is usually the same as the keyboard, that is, one finger is empty above the key.
3. The same structure can be unified with the same fingering, which will be easier to remember.
4, under normal circumstances, the thumb and little finger on the black keys. There can be an exception when the dice go forward.
5, homophones repeat, generally changing fingers.
6. In the case of slow speed, the highest and lowest notes in a short range can be left to the thumb and little finger. In a faster period, it may be awkward because of the weakness of the five fingers, and some changes will be made.
7. The fingers of the left and right hands should correspond as much as possible. Or symmetrical, or the same, or thumb diving at the same time, especially parallel diving.
