What is an ostinato in music?

An ostinato is defined as a repeated musical phrase or rhythm. This term is derived from the Italian word for "obstinate," indicating its persistent nature. In music composition, an ostinato serves as a foundational element that provides continuity and structure throughout a piece. It can appear in various forms, such as a bass line, melodic motif, or rhythmic pattern, and is often used in styles ranging from classical to contemporary genres.

The significance of ostinatos lies in their ability to create a sense of familiarity and drive within a piece, allowing other musical elements to build around them. Composers like Johann Sebastian Bach and modern artists have utilized ostinato effectively to create engaging and memorable works. Understanding the role of ostinato is crucial in analyzing and appreciating the repetitive motifs that often characterize many musical styles.
