In the art of playing the Guqin, a traditional Chinese musical instrument, the continuity of the left hand plays a crucial role. In Guqin performance, the left hand undertakes the task of picking notes according to the string, changing timbre and completing various decorative notes with the right hand. The coherence of the left hand directly affects the fluency of music, the accuracy of emotional expression and the construction of the overall artistic conception of music.

First, from a technical point of view, the coherence of the left hand is reflected in the process of changing strings and walking hand notes. The scale conversion of guqin often requires players to quickly and accurately move their fingers between different positions to achieve seamless connection between notes. This continuous and smooth movement technology not only helps to avoid the rigidity of musical sentences, but also helps to maintain the coherence and integrity of the music, making the music more appealing and dynamic.

Secondly, from the perspective of musical expression, left hand coherence is the key to shaping the unique charm of Guqin music. A major feature of Guqin music is its rich glissando and kneading techniques, such as Yin, 猱, chuo, notes, etc., which are achieved by the flexible and delicate operation of the left hand. Only with superb left hand coherence, can fully show the charm of these skills, so that the music is full of lively atmosphere, as well as deep and distant artistic conception.

Moreover, from the perspective of cultural connotation, Guqin music emphasizes the creation of artistic conception and the transmission of emotion. The continuity of the left hand is like the stroke in calligraphy, which flows freely, has both strength and flexibility, so that every note can be properly stretched and extended, so that the ancient philosophy, emotion and the changes of nature can be vividly presented in the music.

To sum up, the exercise and improvement of the left hand continuity in guqin performance is not only a necessary technical requirement, but also an important link to deepen the musical expression, inheritance and development of the artistic spirit of Guqin. Therefore, both guqin learners and players should attach great importance to the cultivation and practice of left hand coherence.
