Beethoven's Moonlight Sonata, 3rd movement (Presto agitato) as animated sheet music: every storming note lights up as it's played.
The finale of the "Moonlight" Sonata (1801) is the storm after the famous dreamy first movement: rising C♯ minor arpeggios crash into pairs of sforzando chords, a restless second theme sings over a driving left hand, and near the end the music stops for a trill, a cadenza and two bars of Adagio before the final plunge.
