What does ostinato mean in music form?

In music, an ostinato is a repeated musical phrase or rhythm that persists throughout a piece or a section of a composition. It serves as a foundational element, providing a stable backdrop over which other musical ideas can unfold. Ostinatos can occur in various forms, including melodic, harmonic, or rhythmic patterns, and are commonly used in genres ranging from classical to contemporary music. This technique helps create a sense of continuity and can enhance the overall texture of a musical work.
