What is the function of the damper pedal on a piano?

The damper pedal on a piano serves the important function of holding notes and allowing sound to resonate. When the damper pedal is pressed, it lifts the dampers off the strings, which enables the strings to vibrate freely. This prolongs the sound of the notes played, allowing them to blend together harmoniously, creating a more sustained and richer tone. This is particularly useful for creating legato passages and for enhancing the overall resonance of the instrument.

In contrast, the other options reflect different aspects of piano performance or technique that do not relate to the damper pedal's primary purpose. The staccato effect, for instance, involves playing notes in a short and detached manner, which does not require the use of the damper pedal. Enhancing rhythmic accuracy relates more to the pianist's playing technique rather than a specific pedal function. Modulating pitch typically involves techniques such as bending or adjusting the strings' tension, which do not correspond to the damper pedal's abilities.
