The use of the upper glisson is usually manifested as sliding from the lower scale to the higher scale, symbolizing the upsurge of emotions and the openness of artistic conception, giving people a positive, soothing and smooth feeling, which is often seen in the emotional scene of joy, joy or passion.

The lower glissando, on the other hand, is a smooth transition from the higher to the lower scale, creating a deep, long, and poignant musical effect, which is often used to express the emotional atmosphere of melancholy, sadness, or longing.
