👉 Glissades, also known as glissando, are a musical technique used in several genres of music. In classical music, it is often referred to as "glissando" or simply "glissando." This technique involves playing notes at irregular intervals, typically between two different keys, and then gradually increasing the pitch or volume over time. The goal is to create a sense of dissonance, tension, or other musical effects by varying the timing and intensity of the notes played.
