Let's make 1.3 clear at the outset oftentimes I get student papers that refer to Beethoven's 5th sore or to cut his first piano saw that right now that's that that's not good at all these songs but what what do you have to have to make something is so we're actually gonna have a text so we don't have in 80% of classical music we don't have lyrics we don't have a text while yes with upper of course but the other 80% is purely instrumental music it works it's magic again through purity instrumental mean so we can't recall those songs in this puzzle me one day I was sitting there at iTunes and I wanted to buy an interior movement of a Mozart serenade so I was all set to purchase this and it said by some that told me the answer that where this terminology comes in reply because on iTunes we buy I thought it would be purely instrumental but it's called by a sore but we don't want to use that sort of parlance we want to be more but more sophisticated than that if you will and use other terms of War talking generally about Beethoven's composition or Beethoven's piece or Beethoven's work where is Master worker chef d'oeuvre have a good fancy you want to get with it.
