Die Walküre or The Valkyrie, is the second of the four operas that form the cycle Der Ring des Nibelungen (The Ring of the Nibelung), by Richard Wagner. Die Walküre's best-known excerpt is the "Ride of the Valkyries".
Wagner took his tale from the Norse mythology told in the Volsunga Saga and the Poetic Edda.
It received its premiere at the National Theatre Munich on June 26, 1870 at the insistence of King Ludwig II of Bavaria. It premiered in Wagner's Bayreuth Festival as part of the complete cycle on August 14, 1876. This historic first complete studio recording of The Ring is conducted by Sir Georg Solti.
