Many learners begin to learn the erhu, and do not pay much attention to the interaction between the thumb, index finger and ring finger when holding a bow.
If the requirements and essentials of the three fingers in holding the bow are unclear, and the requirements for oneself are not strict, then it will be difficult to coordinate the leverage of the force point, the fulcrum and the key point. Due to the uneven end of the index finger (the bow rod), the wrist is slumped down, the bowing wrist is weak and the force point is unclear, and the bow rod often loses control, causing the 2 mics of the bow rod to slip on the index finger, turning in circles or the wrist is stiff and other problems.
Once the teacher finds that the students have these problems, they should pay great attention to them and correct them in time, so that the students can truly experience: the index finger has a feeling of being lifted up, the thumb has a downward pressing effect, and the middle finger has a kind of feeling when pulling the outer string. The effect of hooking in.
Therefore, holding a bow with fingers is generally summed up in the words "lifting, pressing, topping, and hooking".
Because the quality of holding the bow directly affects the timbre and sound quality of the erhu and the success or failure of the erhu music, teachers must check and correct them repeatedly in the classroom until they truly meet the requirements.
