A child prodigy as a harpsichordist, pianist, and composer, he came to epitomize classical music in its purity of form and melody. A prolific composer, he wrote more than forty symphonies, nearly thirty piano concertos, over twenty string quartets, and sixteen operas, including The Marriage of Figaro (1786), Don Giovanni (1787), Cosi fan tutte (1790), and The Magic Flute (1791).
