The secret of not looking at the hands while playing is: looking at the score and converting the visual symbols into the movements of the hands. Then use the ear to check whether it matches the symbols seen, the music score.
In other words, the first step is to read the score, and the second step is to focus on the movements of the whole body and the touch of the fingertips.
If you're "aged" for more than two years, and are used to looking at the position of the strings before setting them down. So first of all, you need to make an adjustment: enter the state of "playing Tai Chi", slow down the movement, and feel the connection between people and the guzheng.
You need to make a pre-judgment in your mind about the note you see, the upper and lower relationship between it and the next note, and the distance between them.
It’s like when we reach for an object, we don’t need to slowly try to figure out how much distance we need to stretch forward, but the body naturally has a prediction of the distance, and then we can reach the object in an instant. Even if we know in advance where this thing is, we don't need to look at it, we just reach out and grab it.
If you want to master blind bombs, you must develop a keen awareness, perceive how your body moves, feel how the guzheng is in contact with your skin, and create a more intimate relationship between the body and the guzheng.
You can imagine yourself being blind, closing your eyes, playing on the strings in the dark, perceiving bass, mids, treble... When the visual world is closed to you, the sensory world within you becomes more For sharp and rich.
Everyone has the potential of "blind bomb", the key is whether you are willing to develop your own function.
Of course, the teacher can give guidance in class, but whether this function can be fully developed depends on whether you can persevere in communicating with your own body movements and synchronizing vision and movement.
