In music, a lacuna is an intentional, extended passage in a musical work during which no notes are played. A lacuna acts as "negative music" to induce a state of serenity (or tension) in the listener through its contrast to "normal" music consisting of sounded notes. Though no notes are sounded during a lacuna, it is a purposeful and valid musical passage used for a specific effect in the context of the overall work.
