that's a good question. Let's first analyze the situation of the performer in practice on weekdays. Any of our technical majors is very hard in the basic practice on weekdays, whether it is vocal music or instrumental music, it is very boring to practice back and forth for an unknown number of times, and it can gradually deepen the memory of brain behavior in repeated practice, which reflects the phenomenon that the practice works are all familiar from beginning to end. Not only this memory, but also an important one is muscle memory. Muscle memory will be used in many fields, such as bank staff counting money quickly and accurately, and singers can quickly pronounce different pitch heights accurately by training throat muscle memory. . . After the player gets the conditioned reflex from the brain, the muscle memory of his fingers will make him skillfully flip his fingers on the piano without touching other keys. Muscle memorizes the width and number of keys and their hardness. . .

However, music performance (such as piano) is not a complicated action to be completed by some kind of memory. The thought of the brain is the key to produce beautiful and moving strength and speed to deal with the sense of music. The landlord is also right to think of the next note in advance, which is called "thinking ahead". When playing, a small part of attention should be allocated to preparing the following content in advance. It's like a person walking in a place with poor light, but he is very familiar with the route and terrain of this place, so he will not be affected by the darkness and will soon finish the journey.

Therefore, playing is mainly driven by the brain, and at the same time, the muscle memory of the hand will enable the player's fingers to accurately play difficult skills on the piano. Moreover, a small part of attention should be divided to anticipate the part to be played later, so as to be fully prepared psychologically, so as to have a wonderful performance! I hope my answer will help you solve your question.
