Among western musical instruments, violin is an important one. It has played the most important artistic role in the Western Symphony Orchestra and China's Chinese-Western Band, as well as in solos and concertos.

Violin can play two or even three tones at the same time, and can also play four-tone chords alone, which not only enriches the expressive force, but also can be played independently without other instruments. The three-degree, six-degree, eight-degree and ten-degree scale of violin is the basis of playing two tones, and it is also the basic skill that violin players must practice for life.

Playing skills:

When playing the violin, the position of the left finger on the fingerboard is called the handle position. The handle near the piano head is a low handle, and the one near the bridge is a high handle. Changing from one position to another is called changing the handle. There are many ways to change the handle, such as empty string, same finger, different finger and overtone.

It is a sign of insufficient skill training to make an unnecessary sliding sound when changing the handle. In some cases, the sliding sound can change the connection between sounds and add an elegant transition. In particular, the use of sliding sound combined with changing the handle is an expressive means of playing.
