Mozart was a talented musician. His musical talent began to show at the age of 3. He learned piano from his father at the age of 4, composed music at the age of 5, and learned violin from his father at the age of 6. He composed a number of sonatas and symphonies at the age of 8, and wrote his first opera at the age of 11. Throughout his life, he composed numerous piano pieces, sonatas, opera violin concertos, and a large number of instrumental and vocal works of various genres. Together with Beethoven and Haydn, he is known as the three major representatives of classicism. It's a pity that he died early. It’s called Heaven’s Jealousy of Talents. I recommend you to read "The Biography of Mozart". He was also very kind, very childish, a music lunatic with a bit of a weird temper, and was ostracized by his fellow musicians.

A very famous genius! "Little Star" was written when he was 5 years old.
