Wolfgang Amadeus Mozart was an influential classical era composer born in 1756 in Salzburg, Austria. He began composing at age 4 and was taught music by his father Leopold Mozart, who was a court composer. Mozart lived in Salzburg until 1773 and produced many famous works throughout his life, though he died in 1791 at age 35 in Vienna, Austria in poverty and in deteriorating health while working on his Requiem Mass.
