Wolfgang Amadeus Mozart was an Austrian composer and pianist. He was born
in Salzburg in 1756. From a very early age, his family knew that Wolfgang had a
very special musical talent, so his father left work and taught his son music.
Mozart wrote his first piece
music when he was just four years old and gave
his first concert at the age of five. In his lifetime, Mozart went to many countries to
perform his work and met a lot of famous people. He died in 1791 at the age of thirty
five. During his short life, he composed over six hundred pieces of music.
