Wolfgang Amadeus Mozart, baptised as Johannes Chrysostomus Wolfgangus Theophilus Mozart, was a prolific and influential composer of the Classical period.
Born in Salzburg, in the Holy Roman Empire, Mozart showed prodigious ability from his earliest childhood. Already competent on keyboard and violin, he composed from the age of five and performed before European royalty. At 17, Mozart was engaged as a musician at the Salzburg court but grew restless and travelled in search of a better position. While visiting Vienna in 1781, he was dismissed from his Salzburg position. He chose to stay in Vienna, where he achieved fame but little financial security. During his final years in Vienna, he composed many of his best-known symphonies, concertos, and operas, and portions of the Requiem, which was largely unfinished at the time of his early death at the age of 35. The circumstances of his death have been much mythologized.
He composed more than 600 works, many of which are acknowledged as pinnacles of symphonic, concertante, chamber, operatic, and choral music. He is considered among the greatest classical composers of all time, and his influence on Western music is profound. Ludwig van Beethoven composed his early works in the shadow of Mozart, and Joseph Haydn wrote: "posterity will not see such a talent again in 100 years".
