Ok, so I'm gonna go all music nerd now...
I usually try to find music that matches my mood, in order to express it and thereby resolve it. I find that Beethoven is a genius for the deep down hurt, the quiet aching kind. Cliche, but Moonlight Sonata is fantasic. Movement I is sad...Movement III is angry. For full on despair, mvmt II of Symphony No. 7.
When I feel angry or betrayed, Shostokovich's The Execution of Stepan Razin. Nothing like an unjust beheading and a fat tzar to bring out the noble Russian proletariat in you.
If I need an actual pick-me-up, I listen to Torke's Javelin. Minimalist, very bright. Or Holst, the Planets, Jupiter. One can't help but smile.
Right now, my favorite for the full emotional ride is Tchaikovsky Symphony No. 6, the Pathetique. We performed it last night, and the last movement was so powerful, the applause at the end seemed innappropriate, out of place.
ok, I'm done^.^
