Ludwig van Beethoven

Beethoven redefined the boundaries of orchestral music with 9 symphonies and 32 piano sonatas, including the legendary 5th and 9th Symphonies, the latter completed while profoundly deaf. His works remain the most performed in the classical canon, with the 9th Symphony alone performed over 10,000 times annually worldwide, a frequency 30% higher than the average top-10 composer's most performed piece. This output outperforms #2 Mozart in both structural innovation and emotional depth, as Beethoven's late quartets and piano sonatas pioneered Romantic expression while Mozart's remained largely Classical in form.
