As well as many great masterpieces, Mozart wrote many pieces in a more popular style, including some tunes that everybody knows today. His serenade "Eine kleine Nachtmusik K525" is known everywhere, as is the "Turkish Rondo" from his "Piano Sonata in A K331", the opening of the "Symphony No. 40 in G minor K550", and the birdcatcher’s song from "The Magic Flute K620."
