Erhu solo "Horse Racing" is a well-known song, and people who like to listen to and play Erhu know it. In the song, in order to express the horse racing scene, the author uses the technique of "plucking the strings" to express and imitate the sound of horseshoes. Pay attention to the following points when plucking the erhu: 1. When plucking the strings with your right hand, don't use too much force, and relax naturally. You basically use the metacarpal joint of your right index finger to pluck the strings with the strength of wrist relaxation. Never pull the string rigidly with your whole hand. 2. When the left hand presses each tone separately, the right hand should move the contact position of the plucked string up and down with the different phonemes of the left hand. The contact point of the plucked string should always be in the middle between the finger point and the piano code point. According to the principle of string vibration, the strings thus dialed vibrate best; This is also the best timbre and resonance. It is much better to pluck the strings like this than many people pluck the strings in one position with their right hands. But it also increases the difficulty. 3. From the strength analysis, I think that with the ups and downs of the melody, the plucking strength of the right hand should also change from strong to weak. In this piece of music, the more you dial down with your right hand, the greater the intensity, so as to ensure the consistency of the whole plucked string in volume.
