Valkyrie
Richard Wagner composed some operas featuring Valkyries (German: Walküren, singular: Walküre). These operas are Die Walküre, Siegfried, and Götterdämmerung. They feature a story of a Valkyrie Brünnhilde, her punishment for disobeying her father, and her falling in love with Siegfried.  The music for the opening of Act Three of Die Walküre is very famous. It is called the Ride of the Valkyries.
