agitato

Agitato tells the performer to play with a restless, uneasy quality. It affects both the character and pacing of the music, often implying slight urgency without specifying an exact tempo. The mood should feel unsettled, as though the music is driven by nervous energy. Beethoven used agitato to powerful effect in the first movement of his Moonlight Sonata (marked Adagio sostenuto, but with agitato passages). The marking appears across all genres and periods, and performers must convey the emotional turbulence through touch, timing, and dynamics rather than simply playing faster.
