In music, the term "piano" refers to a dynamic marking indicating that a piece or passage should be played softly. Originating from the Italian word "pianoforte," which means "soft-loud," it instructs musicians to produce a gentle sound. The term is often placed in sheet music to guide performers in adjusting their volume. Additionally, "piano" is also the name of the musical instrument known for its wide range and versatility, capable of producing both soft and loud sounds depending on how the keys are struck.
