Some friends are prone to misunderstandings when they see "weak" and "very weak" marks on the score. I thought it should be played very lightly, so I used very little strength to play it very lightly, but the sound that came out was hollow and did not travel far, and it sounded vague. This problem is due to a misunderstanding of the force written on the score as "weak" and "very weak".

It is conceivable that when we want to catch a butterfly parked on a branch, your movements must be light enough to not let the butterfly fly away. At this point you can feel that your fingers, wrists and forearms are in control. You will control and secretly move your hand to the butterfly with a lot of force, grabbing the butterfly unexpectedly. At this time, you can feel that the three fingers grasping the butterfly and other parts of the hand used a lot of force, especially the three fingertips of the big finger, the second finger and the third finger. He made a nervous and sudden movement. The process of exerting force is always in the process of gentleness. This experience can inspire students to understand the "weak" sound of playing, not without force. In addition, students can also be asked to walk on their toes. In order not to wake up and cut people, they need to gently lift and lower the force of such control. The toes have a great bearing capacity. Therefore, for playing "weak" sounds, it is necessary to adjust the strength of the control and the speed of touching the strings, depending on the nature of the music, in order to produce satisfactory results.
