For me the saddest music, and one I've asked my wife to play at my
funeral (sorry to get morbid here) is the adagio movement from Bruckner's
7th symphony.  It is said that Bruckner wrote it as an elegy for Wagner,
and even calls for Wagner tubas in the score.  I find myself quite
overwhelmed whenever I hear this movement.
