What is an "ostinato" in music?

An ostinato in music refers to a repeated musical phrase or rhythmic pattern. This can occur in various forms, such as a melodic line that recurs throughout a piece or a specific rhythm that underlies different musical sections. The use of an ostinato can create a sense of continuity and can build tension or drive the music forward, allowing for other layers of music to be developed over it. This technique is widely used across different genres, from classical compositions to contemporary music, making it a fundamental concept in music theory and practice.

Understanding the concept of an ostinato helps to grasp how repetition can enhance musical structure and emotional impact in a piece.
