Which of the following instruments is typically associated with Cuban Salsa music?

The piano is a central instrument in Cuban Salsa music, also known as salsa dura or "hard salsa." In this genre, the piano contributes significantly to the harmonic structure and rhythmic texture. It is often used to play both intricate melodic lines and syncopated rhythms that are characteristic of salsa music. The piano also interacts with other instruments, such as horns and percussion, creating the vibrant and energetic sound that is a hallmark of salsa.

While other instruments like the saxophone and guitar can be found in salsa, the piano's role in providing both accompaniment and melodic content is crucial in this musical style, making it a defining feature of Cuban salsa music. The marimba, although used in some Latin music genres, is not typically associated with salsa, which leans more heavily on the rhythms and sounds of percussion and brass instruments. Thus, the piano stands out as the most recognized and integral instrument in this context.
