Otello (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Arrigo Boito, based on Shakespeare's play "Othello".
 It was Verdi's penultimate opera, and was first performed at the Teatro alla Scala, Milan, on 5 February 1887.
Die Walküre (The Valkyrie), WWV 86B, is a music drama in three acts by Richard Wagner with a German libretto by the composer.
 It is the second of the four works that form Wagner's cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
Wilhelm Richard Wagner ( ; ] ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas").
 Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works.
 Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama.
 He described this vision in a series of essays published between 1849 and 1852.
 Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
Der Ring des Nibelungen (The Ring of the Nibelung), WWV 86, is a cycle of four German-language epic music dramas composed by Richard Wagner.
 The works are based loosely on characters from the Norse sagas and the "Nibelungenlied".
 The composer termed the cycle a "Bühnenfestspiel" (stage festival play), structured in three days preceded by a " " ("preliminary evening").
 It is often referred to as the Ring Cycle, "Wagner's Ring", or simply "The Ring".

Götterdämmerung ( ; Twilight of the Gods), WWV 86D, is the last in Richard Wagner's cycle of four music dramas titled "Der Ring des Nibelungen " ("The Ring of the Nibelung", or "The Ring" for short).
 It received its premiere at the Bayreuth Festspielhaus on 17 August 1876, as part of the first complete performance of the "Ring".
The Rhinemaidens are the three water-nymphs ("Rheintöchter" or "Rhine daughters") who appear in Richard Wagner's opera cycle "Der Ring des Nibelungen".
 Their individual names are Woglinde, Wellgunde and Flosshilde (Floßhilde), although they are generally treated as a single entity and they act together accordingly.
 Of the 34 characters in the "Ring" cycle, they are the only ones who did not originate in the Old Norse "Eddas".
 Wagner created his Rhinemaidens from other legends and myths, most notably the "Nibelungenlied" which contains stories involving water-sprites (nixies) or mermaids.
 The key concepts associated with the Rhinemaidens in the "Ring" operas—their flawed guardianship of the Rhine gold, and the condition (the renunciation of love) through which the gold could be stolen from them and then transformed into a means of obtaining world power—are wholly Wagner's own invention, and are the elements that initiate and propel the entire drama.
Siegfried, WWV 86C, is the third of the four music dramas that constitute "Der Ring des Nibelungen" ("The Ring of the Nibelung"), by Richard Wagner.
 It premiered at the Bayreuth Festspielhaus on 16 August 1876, as part of the first complete performance of "The Ring" cycle.
