full_context: Document 1: Buckingham Palace: Before Prince Albert's death, the palace was frequently the scene of musical entertainments, and the greatest contemporary musicians entertained at Buckingham Palace. The composer Felix Mendelssohn is known to have played there on three occasions. Johann Strauss II and his orchestra played there when in England. Strauss's "Alice Polka" was first performed at the palace in 1849 in honour of the queen's daughter, Princess Alice.

Document 3: Economy of Switzerland: The economy of Switzerland is one of the world's most stable economies. The service sector has also come to play a significant economic role, particularly the Swiss banking industry and tourism. The economy of Switzerland ranks first in the world in the 2015 Global Innovation Index and the 2017 Global Competitiveness Report. According to United Nations data for 2016, Switzerland is the third richest landlocked country in the world after Liechtenstein and Luxembourg, and together with Norway the only two countries in the world with a GDP per capita above US $70,000 that are neither island nations nor ministates.
Document 4: Johann Strauss III: Johann Strauss III (16 February 18669 January 1939; ; also known as Johann Maria Eduard Strauss) was an Austrian composer whose father was Eduard Strauss, whose uncles were Johann Strauss II and Josef Strauss, and whose grandfather was Johann Strauss I. He was unofficially entrusted with the task of upholding his family's tradition after the dissolution of the Strauss Orchestra by his father in 1901. His talents were not fully realized during his lifetime as musical tastes had changed in the Silver Age with more popular composers such as Franz Lehár and Oscar Straus dominating the Viennese musical scene with their operettas, although his uncle, Johann Strauss II, supervised his development as a musician, a fact disputed by Eduard Strauss.
Document 5: Switzerland: Switzerland is one of the richest and wealthiest countries in the world. Switzerland ranks top or close to the top in several metrics of national performance, including government transparency, civil liberties, quality of life, economic competitiveness, and human development. It has the highest nominal wealth (financial and non-financial assets) per adult in the world according to Credit Suisse and the eighth-highest per capita gross domestic product on the IMF list. Zürich and Geneva have each been ranked among the top cities with the highest quality of life in the world, with the former ranked 2nd globally, according to Mercer.
Document 6: Classical period (music): However, Vienna's fall as the most important musical center for orchestral composition during the late 1820s, precipitated by the deaths of Beethoven and Schubert, marked the Classical style's final eclipse -- and the end of its continuous organic development of one composer learning in close proximity to others. Franz Liszt and Frédéric Chopin visited Vienna when they were young, but they then moved on to other cities. Composers such as Carl Czerny, while deeply influenced by Beethoven, also searched for new ideas and new forms to contain the larger world of musical expression and performance in which they lived.
Document 7: Johann Strauss III: Despite his keen interest in composing, he was better remembered as a conductor. His only stage work, the three-act operetta "Katze und Maus", composed in 1898, premiered in Vienna on 23 December 1898, at the Theater an der Wien. Its public reaction bordered on utter dislike, and music critics called for the distraught composer to reassess himself and to appear under a pseudonym, in order not to tarnish the name of his famous relatives. He salvaged the music score and produced independent pieces of which the waltzes "Sylvanien", Op. 1 and "Leonie", Op. 2 survived obscurity.
Document 8: Aschenbrödel: Aschenbrödel ("Cinderella") is a ballet written by Johann Strauss II. He had written all the principal parts of the ballet, and was intending to fill in the orchestration as time permitted. However, Strauss died in 1899, and it was finished by composer Josef Bayer in 1900.
Document 9: Switzerland: Switzerland has an overwhelmingly private sector economy and low tax rates by Western World standards; overall taxation is one of the smallest of developed countries. Switzerland is a relatively easy place to do business, currently ranking 20th of 189 countries in the Ease of Doing Business Index. The slow growth Switzerland experienced in the 1990s and the early 2000s has brought greater support for economic reforms and harmonization with the European Union. According to Credit Suisse, only about 37% of residents own their own homes, one of the lowest rates of home ownership in Europe. Housing and food price levels were 171% and 145% of the EU-25 index in 2007, compared to 113% and 104% in Germany.
Document 10: Rhine: The Rhine emerges from Lake Constance, flows generally westward, as the Hochrhein, passes the Rhine Falls, and is joined by its major tributary, the river Aare. The Aare more than doubles the Rhine's water discharge, to an average of nearly 1,000 m3/s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn, the highest point of the Rhine basin. The Rhine roughly forms the German-Swiss border from Lake Constance with the exceptions of the canton of Schaffhausen and parts of the cantons of Zürich and Basel-Stadt, until it turns north at the so-called Rhine knee at Basel, leaving Switzerland.
Document 11: Switzerland: The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP – per capita). In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD. Switzerland also has one of the world's largest account balances as a percentage of GDP.

Document 13: Rhine: The Rhine (Latin: Rhenus, Romansh: Rein, German: Rhein, French: le Rhin, Dutch: Rijn) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss - Liechtenstein, Swiss - Austrian, Swiss - German and then the Franco - German border, then flows through the German Rhineland and the Netherlands and eventually empties into the North Sea.
Document 14: Frédéric Chopin: Chopin's music was used in the 1909 ballet Chopiniana, choreographed by Michel Fokine and orchestrated by Alexander Glazunov. Sergei Diaghilev commissioned additional orchestrations—from Stravinsky, Anatoly Lyadov, Sergei Taneyev and Nikolai Tcherepnin—for later productions, which used the title Les Sylphides.
Document 15: Rhine: Near Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Rhine. The river makes a distinctive turn to the north near Chur. This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley (German: Rheintal). Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the river Aare. The Alpine Rhine begins in the most western part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the West and Liechtenstein and later Austria to the East.
