The waltz is a ballroom and folk dance in  triple (help·info) time, performed primarily in closed position.

There are several references to a sliding or gliding dance,- a waltz, from the 16th century including the representations of the printer H.S. Beheim. The French philosopher Montaigne wrote of a dance he saw in 1580 in Augsburg, where the dancers held each other so closely that their faces touched. Kunz Haas, of approximately the same period wrote that, "Now they are dancing the godless, Weller or Spinner." "The vigorous peasant dancer, following an instinctive knowledge of the weight of fall, utilizes his surplus energy to press all his strength into the proper beat of the measure, thus intensifying his personal enjoyment in dancing". The wide, wild steps of the country people became shorter and more elegant when introduced to higher society. Hans Sachs wrote of the dance in his 1568 Eygentliche Beschreibung aller Stände (1568).

At the Austrian Court in Vienna in the late 17th century (1698) ladies were conducted around the room to the tune of a 2-beat measure, which then became the 3/4 of the Nach Tanz (After Dance), upon which couples got into the position for the Weller and waltzed around the room with gliding steps as in an engraving of the Wirtschaft (Inn Festival) given for Peter the Great.

Dmitri Dmitriyevich Shostakovich Russian pronunciation: [ˈdmʲitrʲɪj ˈdmʲitrʲɪɪvʲɪt͡ɕ ʂəstɐˈkovʲɪt͡ɕ] (Russian: Дмитрий Дмитриевич Шостакович; 25 September 1906 – 9 August 1975) was a Soviet Russian composer and pianist and was one of the most celebrated composers of the 20th century.

Shostakovich achieved fame in the Soviet Union under the patronage of Leon Trotsky's chief of staff Mikhail Tukhachevsky, but later had a complex and difficult relationship with the government. Nevertheless, he received accolades and state awards and served in the Supreme Soviet of the RSFSR (1947–1962) and the USSR (from 1962 until death).

After a period influenced by Sergei Prokofiev and Igor Stravinsky, Shostakovich developed a hybrid style, as exemplified by Lady Macbeth of the Mtsensk District (1934). This single work juxtaposed a wide variety of trends, including the neo-classical style (showing the influence of Stravinsky) and post-Romanticism (after Gustav Mahler). Sharp contrasts and elements of the grotesque characterize much of his music.

Johann Strauss II (October 25, 1825 – June 3, 1899), also known as Johann Baptist Strauss or Johann Strauss, Jr., the Younger, or the Son (German: Sohn), was an Austrian composer of light music, particularly dance music and operettas. He composed over 500 waltzes, polkas, quadrilles, and other types of dance music, as well as several operettas and a ballet. In his lifetime, he was known as "The Waltz King", and was largely then responsible for the popularity of the waltz in Vienna during the 19th century.

Strauss was born in St. Ulrich (now a part of Neubau), the son of Johann Strauss I, another composer of dance music. His father did not wish him to become a composer, but rather a banker; however, the son defied his father's wishes, and went on to study music with the composer Joseph Drechsler and the violin with Anton Kollmann, the ballet répétiteur of the Vienna Court Opera. Strauss had two younger brothers, Josef and Eduard Strauss, who became composers of light music as well, although they were never as well known as their elder brother.

Queen Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was the monarch of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. From 1 May 1876, she used the additional title of Empress of India.

Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn, the fourth son of King George III. Both the Duke of Kent and the King died in 1820, and Victoria was raised under close supervision by her German-born mother Princess Victoria of Saxe-Coburg-Saalfeld. She inherited the throne at the age of 18, after her father's three elder brothers had all died without surviving legitimate issue. The United Kingdom was already an established constitutional monarchy, in which the Sovereign held relatively few direct political powers. Privately, she attempted to influence government policy and ministerial appointments. Publicly, she became a national icon, and was identified with strict standards of personal morality.

She married her first cousin, Prince Albert of Saxe-Coburg and Gotha, in 1840. Their nine children and 26 of their 34 grandchildren who survived childhood married into royal and noble families across the continent, tying them together and earning her the nickname "the grandmother of Europe". After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, republicanism temporarily gained strength, but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration.

Maria João Pires (Portuguese pronunciation: [mɐˈɾiɐ ʒuˈɐ̃w ˈpiɾɨʃ]; born in Lisbon, Portugal, July 23, 1944) is a Portuguese pianist.

Her first recital was at the age of five, and at the age of seven she was already playing Mozart Piano Concertos publicly. Two years later she received Portugal's top prize for young musicians. In the following years, she studied with Professor Campos Coelho at the Lisbon Conservatory, taking courses in composition, theory, and history of music. She continued her studies in Germany, first in the Musikakademie of Munich with Rosl Schmidt and then in Hanover with Karl Engel.

International fame came in 1970, when she won the Beethoven Bicentennial Competition in Brussels. She has since then regularly performed with major orchestras throughout the world, interpreting works by Bach, Beethoven, Schumann, Schubert, Mozart, Brahms, Chopin and many other classical and romantic composers. She appears regularly with major world orchestras in Europe, America, Canada, Israel and Japan.
