Here is a question about this article: The Wagner tuba, a modified member of the horn family, appears in Richard Wagner's cycle Der Ring des Nibelungen and several other works by Strauss, Béla Bartók, and others; it has a prominent role in Anton Bruckner's Symphony No. 7 in E Major. Cornets appear in Pyotr Ilyich Tchaikovsky's ballet Swan Lake, Claude Debussy's La Mer, and several orchestral works by Hector Berlioz. Unless these instruments are played by members doubling on another instrument (for example, a trombone player changing to euphonium for a certain passage), orchestras will use freelance musicians to augment their regular rosters.
What is the answer to this question: Who wrote the ballet Swan Lake?
****
So... Pyotr Ilyich Tchaikovsky


Here is a question about this article: John's position in France was considerably strengthened by the victory at Mirebeau, but John's treatment of his new prisoners and of his ally, William de Roches, quickly undermined these gains. De Roches was a powerful Anjou noble, but John largely ignored him, causing considerable offence, whilst the king kept the rebel leaders in such bad conditions that twenty-two of them died. At this time most of the regional nobility were closely linked through kinship, and this behaviour towards their relatives was regarded as unacceptable. William de Roches and other of John's regional allies in Anjou and Brittany deserted him in favour of Philip, and Brittany rose in fresh revolt. John's financial situation was tenuous: once factors such as the comparative military costs of materiel and soldiers were taken into account, Philip enjoyed a considerable, although not overwhelming, advantage of resources over John.[nb 6]
What is the answer to this question: What victory strengthened John's position?

So... Mirebeau


Here is a question about this article: In 1409, a hospital was founded and placed under the patronage of Santa María de los Inocentes; to this was attached a confraternity devoted to recovering the bodies of the unfriended dead in the city and within a radius of three miles (4.8 km) around it. At the end of the 15th century this confraternity separated from the hospital, and continued its work under the name of "Cofradia para el ámparo de los desamparados". King Philip IV of Spain and the Duke of Arcos suggested the building of the new chapel, and in 1647 the Viceroy, Conde de Oropesa, who had been preserved from the bubonic plague, insisted on carrying out their project. The Blessed Virgin was proclaimed patroness of the city under the title of Virgen de los desamparados (Virgin of the Forsaken), and Archbishop Pedro de Urbina, on 31 June 1652, laid the cornerstone of the new chapel of this name. The archiepiscopal palace, a grain market in the time of the Moors, is simple in design, with an inside cloister and a handsome chapel. In 1357, the arch that connects it with the cathedral was built. In the council chamber are preserved the portraits of all the prelates of Valencia.
What is the answer to this question: What was the confraternity called after its separation from the hospital?
