the basic technique of changing the shape of the palm. Next, we will talk about the finger-shaping. Before we talk about the finger-shaping, please recall the way of touching the strings with the left hand. The palm of the hand is facing down. The palm of the hand is placed on the strings one by one. The palm of the hand naturally becomes a half-shape. Try to leave as much space as possible between the palms of the hands. In this way, when we press the strings, the space between the palms will be larger. When we press the strings with the little finger, the palm of the hand must be placed down together. It's not easy to press the strings with the little finger when we press the strings with the left hand. Because the little finger is short. The distance from the thumb is also the longest. So when we press the strings with the little finger, the palm must be placed down together. So when we press the strings with the little finger, the distance from the thumb is also the longest. But the palm of the hand must be placed down together. It's not easy to press the strings with the little finger when we press the strings with the right hand. When we press the strings with the little finger, we must pay attention to the shift of the center of gravity of the hand. The shift of the center of gravity of the hand is like this. The back of the hand shifts from side to side. Let me show you another exercise. Repeat this exercise for each group. Repeat this exercise for each group. The thumb and the little finger must be fully extended. But the top of the hand must not be extended. When we extend the fingers, the pinky is the thumb of the finger to the face of the finger. We also need to straighten the back of the hand as if to pull something down. The initiative should form a **shape like this. Let's try it again. Let's try it again. Let's try it again. Let's try it again. Let's learn the key tone. Please look at this picture. This is the key tone picture. This is the key tone picture. What we have learned so far is the key tone fingering. It is not difficult to find the key tone and key tone from the picture. It is not difficult to find the key tone and key tone from the picture. The difference is that the key tone finger joint is moved to the second finger on the second finger. The key tone fingering is on the second finger. The key tone finger joint is still on the second and third fingers. The key tone finger joint is still on the second and third fingers.
