Ludwig van Beethoven, Mozart's junior by fifteen years, was deeply influenced by his work, with which he was acquainted as a teenager. He is thought to have performed Mozart's operas while playing in the court orchestra at Bonn and travelled to Vienna in 1787 hoping to study with the older composer. Some of have direct models in comparable works by Mozart, and he wrote cadenzas (WoO 58) to Mozart's D minor piano concerto K. 466. For further details, see Mozart and Beethoven.
