Stravinsky's Firebird Suite is really quite beautiful. Every time I listen to it, I can't help but to be reminded of a firebird's mythical wings fluttering in the wind. The music portrays the fleeting movements of the firebird so well. It's actually quite a magical feeling.

Go experience it for yourself! Listen to this:
