Did you say mourning music? Let's see.  Chopin's infamous "Funeral Sonata,
Berlioz Grand Symphonie Funebre et Triumphale for Band and Optical Chorus,
the slow movement of the Eroica and Mozart's Requiem Mass.

Wait a minute, someone is tapping me on the shoulder. What, oh! Morning.
Easy. Grieg's Peer Gynt Suite.

Sorry but I am going deaf and dumb.
