Wolfgang Amadeus Mozart was a one-of-kind musician. He rose to fame when he was a child and played piano or violin in concerts throughout central Europe during his childhood. As an adult, Mozart became a highly productive composer and greatly sought after. During his lifetime he composed 41 symphonies, 22 operas, 23 piano concertos, multiple works for choirs, and hundreds of pieces for solo instruments. This is even more impressive since he died at age 35.
