Following on from the Beautiful Tracks thread, I thought of a few classical pieces that would fit the bill, but that thread went in a different direction, and anyway classical music is such a broad category I think it deserves a thread of its own. So, if you have a favourite classical tune or composer or if you've heard a piece on TV or films that you don't know the name of, post it up on here. Extra points if it's quite obscure.

The description 'classical' can be fairly loose - anything from opera (Bizet's Pearl Fishers duet holds a special place in my heart), film (Schindler's List) or even video games (the sig from Fallout 3 and the piano version in 4 are favourites of mine) is fine.

To kick off, the first one I thought of for the Beautiful Tracks thread was The Gadfly Romance by Shostakovich (try the second movement of his second piano concerto too) - https://www.youtube.com/watch?v=Q0Xfyn0-YhU
