Although the erhu has only two strings, it is very expressive. It takes effort to pull it well. On the one hand, it is necessary to master the skill of bowing with the right hand, and on the other hand, it is the proficiency of the left fingering. Because the erhu is not a fixed-pitch instrument, each note is controlled by the player's fingers. Solving the problem of intonation is one of the biggest problems of erhu, and it is necessary to have a good concept of intonation. The technique of bowing and changing strings with the right hand will also affect the sound quality, timbre and tone consistency of the music melody. Therefore, to pull the erhu well requires the tacit cooperation of both hands.

The intonation of the erhu is very important. When playing, it is mainly listened to by ear. Even if the position is correct, slight changes will affect the accuracy of the pitch. Beginners should master the knowledge of semitone and whole tone. Correct holding of the piano (hand shape) and the skills of changing the handle are the foundation of playing the erhu well.
