Definition

An ostinato is a persistently repeated musical phrase, motif, or pattern that forms a structural foundation of a composition. Its parameters are duration (how long the pattern repeats), register (the pitch range where it sits), and variation (the degree to which the pattern changes while maintaining its recognizability). [formal: ostinato | substrate: mind | horizon: a piece | explicit: yes | epoch: 0.01]

Why it is in scope

A human-made musical concept — a short melodic, rhythmic, or harmonic phrase that is persistently repeated throughout a composition to provide structural coherence. Built to persist through notation, performance practice, and music-theory pedagogy.
