This clip is taken from the hit movie "Amadeus". It shows Antonio Salieri's piece being played by the Hapsburg Monarch at the time.
While the piece was written by Salieri, the monarch plays it but fails to play it properly when Mozart is summoned to discuss a matter of a future opera that he wants Mozart to compose and write. Mozart accepts with honour and plays Salieri's song perfectly and perfects it.
This clip depicts the first time Salieri hates Mozart and God for creating Mozart. He blames God for using Mozart as his instrument of sound and is 'laughing at Salieri through that histarical laugh'.
