It is an Italianized musical term derived from the French glisser, "to glide". In some contexts, it is equivalent to portamento, which is a continuous, seamless glide between notes. In other contexts, it refers to discrete, stepped glides across notes, such as on a piano. Some terms that are similar or equivalent in some contexts are slide, sweep bend, smear, rip (for a loud, violent glissando to the beginning of a note), lip (in jazz terminology, when executed by changing one's embouchure on a wind instrument), plop, or falling hail (a glissando on a harp using the back of the fingernails). On wind instruments, a scoop is a glissando ascending to the onset of a note achieved entirely with the embouchure, except on instruments that have a slide (such as a trombone).
