What characterizes a glissando in music?

A glissando is characterized by a slide between two notes that creates a smooth connection. This technique involves the continuous movement from one pitch to another, which can be executed on various instruments or through vocalization. The effect is a seamless transition that allows the listener to perceive a flowing line rather than distinct, separate pitches.

This sliding motion contrasts with other musical techniques. While harmonic intervals involve a relationship between notes that can create chords or harmonies, a glissando focuses on the linear movement between pitches. Similarly, a rapid succession of notes refers to a series of distinct pitches played in quick succession, which does not result in the smooth continuity characteristic of a glissando. Lastly, a vocal technique emphasizing a single pitch is unrelated since a glissando specifically highlights the transition between different pitches rather than maintaining a singular tonal focus.
