Wolfgang Amadeus Mozart, an Austrian composer, was a prolific artist who created a string of operas, concertos, symphonies and sonatas that significantly shaped classical music. He composed more than 600 works of music,  including the twelve variations on the French folk song "Ah! vous dirai-ie, maman" better known as the famous lullaby Twinkle, Twinkle, Little Star. Today, Mozart is among the most influential classical composers, and his mastery is profound on Western Classical Music.
