What does "mezzo piano" (mp) mean in musical terms?

"Mezzo piano" (mp) is an Italian musical term used to indicate a specific dynamic level in music. It translates to "moderately soft," which means that the performer should play or sing at a volume that is softer than "mezzo forte" (moderately loud) but louder than "piano" (soft). This dynamic marking allows composers to convey nuanced emotional expressions in their music, guiding performers to balance their volume appropriately according to the context of the piece. Understanding these terms helps musicians interpret the score accurately and contribute effectively to the overall performance.
