Wolfgang Amadeus Mozart (27 January 1756 – 5 December 1791) was a Classical composer and musician. In his brief life, he completed more than 800 works including outstanding examples of most of the genres of his time: symphonies, concertos, chamber music, opera, and choral music. Born in Salzburg, Mozart quickly emerged as a child prodigy under the training of his father Leopold, a skilled pedagogue. At age five, he was already competent on keyboard and violin, had begun to compose, and had performed before European royalty. His father took him on a grand tour of Europe and then three trips to Italy. At 17 he was a musician at the Salzburg court but grew restless and travelled in search of a better position. A fruitless journey in search of employment (1777-1779) led him to Paris, Mannheim, Munich, and eventually back to Salzburg. During this time he wrote his five violin concertos, the Sinfonia Concertante, various masses, and the opera Idomeneo.
While he was visiting Vienna in 1781, Mozart's quarrels with his Salzburg employers came to a head and he was dismissed.
