Symphony No. 40 in G minor, K. 550 – Movement I (Molto allegro)

Mozart's Symphony No. 40 in G minor, K. 550 (1788) is one of only two symphonies he wrote in a minor key and stands as a pinnacle of the Classical period, marked by its urgency and emotional intensity unusual for the time. The famous opening motif — a falling third followed by a longer note — is one of the most instantly recognizable openings in all of classical music.
