From the perspective of a violinist, the violin is a tool for expressing emotions. This tool is useful and should provide assistance to their performance, allowing them to express their emotions fluently and fully. Specifically, if a violinist wants to play light passages, he only needs to use a small amount of bow hair and lightly touch the strings, and the violin can sing softly; And he wants to play a loud voice, as long as he applies force to the bow, the violin will be like an oil fueled engine, with abundant power, continuously emitting full sound, crossing space, and reaching the audience. Its tone is pure, melodious, and rich in singing quality. The bass is deep, and the treble is bright.

The sound style of violin can be divided into three categories: one is' masculine beauty '- rich and unrestrained, deep and profound, bright and round, grand and majestic; The second 'beauty of softness' - implicit and elegant, delicate and concentrated, pure and gorgeous, melancholic and mysterious; The third 'beauty of the mean' - loose and warm, thick and bright balance, balance of hardness and softness, and profound humor.

Specifically on each string, it is manifested as: the E string is clear and bright, the A string is soft and melodious, the D string is elegant, and the G string is deep and profound.
