Which aspect of Cuban Salsa is characterized by repetition?

Cuban Salsa is known for its vibrant and rhythmic qualities, one of which is the use of ostinato. An ostinato is a musical phrase or rhythm that is persistently repeated throughout a piece of music. In the context of Cuban Salsa, this repetition often appears in the rhythmic patterns played by the piano, percussion, or other instruments, creating a foundation that supports the improvisation and melodies played over it.

This repetitiveness is essential as it establishes a strong rhythmic groove, allowing dancers and musicians to connect to the music on a deeper level. It contributes to the lively and infectious pulse that characterizes Salsa music and invites participation through dancing.

While other elements such as melody, harmony, and dynamics play important roles in music, it is the ostinato that distinctly highlights the repetitive feature in Cuban Salsa, thus making it the correct choice for the question.
