From a traditional perspective, the timbre of the violin can be divided into "cool colors", including emotional characteristics such as sadness, sadness, melancholy, desolation, and pain. It is generally reflected through the slow bow, long bow, or middle bow of the violin, and the strength generally includes variations such as light, gentle, and gravity; The "warm color" of the violin can include various changes in tone colors such as "warm" and "intense", including emotional characteristics such as lightness, clarity, aggressiveness, and masculinity; There is also a more modern timbre characteristic - "intermediate color", which is not a timbre between "cool color" and "warm color", but more refers to rare types of timbres with noise properties and unconventional performances. These timbres are mainly used to express hysteria, excessive pain, unconventional moans, crazy madness, neurotic emotional changes, etc. All of these timbre types have become the best medium for interpreting music works with various stylistic features, infused with the humanized elements of the performer.

The different types of violin timbres are closely related to the design of the instrument, playing techniques, and the emotional characteristics of the performer. For example, playing with two different mechanisms, plucking and pulling, when calm and composed, can produce stable emotional induction characteristics due to the relatively stable vibration state parameters of the strings. If a high-intensity performance is performed during a sudden change in the psychological state of the performer, it will have a profound impact on the vibration displacement, period, phase change, transient and enveloping state of the string vibration at various points on the string, resulting in a color change from "warm color" to "intermediate color". The friction and vibration between the bow strings of the violin greatly affect the "fusion" of instrument performance and human technical factors; On the other hand, factors such as string pressing techniques and finger techniques of the violin also greatly affect the changes in its timbre. Therefore, these are important elements that affect the performance of violin timbre, and they are also important principles to follow in the process of discovering the "intermediate" timbre required for the expression of modern music works.

The relationship between the timbre types of violin and its expressive objects

Before the early 1970s, the timbre types of violins were mainly based on relatively traditional "warm" and "cool" tones. Even during the exploration of impressionist music, expressionist music, and experimental color electronic music in Europe and America, they were mostly based on traditional tonal systems. The exploration of timbre in violin performance is also based on the logical foundation of these modes and tonality. But in the 1970s, achievements began to emerge in exploring deeper fields based on breaking free from the constraints of tonal music - differential audio spectrum music that embodies the principle of sound vibration. This kind of music can be seen as the crystallization of the deepening development of electronic music, or as the inevitable result of technological development. Over the past few decades, with the continuous updating and development of composition concepts and performance techniques, more and more works of differential audio spectrum music have emerged, and masterpieces have also begun to emerge more and more on the world music stage.
