Use one or more fingers to sweep several strings outward rapidly. A general term.

A category using the same finger to sweep across multiple strings in whatever rhythm is indicated by the music. These techniques are played over multiple beats and changing rhythms. They allow every note to be heard individually. This is different from glissando, which blend the sound of many strings together. Named examples are:

If using own nail, only the pad of the thumb touches the strings. Kwok goes on to say that the technique is usually found with a pitch bend and a slight vibrato; no other sources mention this.
