The ländler is a folk dance in 3/4 time which was popular in Austria, south Germany, German Switzerland, and Slovenia at the end of the 18th century.

It is a dance for couples which strongly features hopping and stamping. It was sometimes purely instrumental and sometimes had a vocal part, sometimes featuring yodeling.

When dance halls became popular in Europe in the 19th century, the ländler was made quicker and more elegant, and the men shed the hobnail boots which they wore to dance it. Along with a number of other folk dances from Germany and Bohemia, it is thought to have contributed to the evolution of the waltz.

A number of classical composers wrote or included ländler in their music, including Ludwig van Beethoven, Franz Schubert and Anton Bruckner. In several of his symphonies Gustav Mahler replaced the scherzo with a ländler. The Carinthian folk tune quoted in Alban Berg's Violin Concerto is a ländler, and another features in Act II of his opera Wozzeck. The "German Dances" of Wolfgang Amadeus Mozart and Joseph Haydn also resemble ländler. Britten's Peter Grimes features a Ländler in the scene where a dance night is occurring in the Hall.

Anton Karas (July 7, 1906 – January 10, 1985) was a Viennese zither player, best known for his soundtrack to Carol Reed's The Third Man.

Born in Vienna, of Hungarian and Czech origin, one of five children of a factory worker, Anton Karas was already keen on music as a child. He desired to become a band leader, which due to the family's financial situation was impossible. However, he was allowed to learn to play an instrument, as were his two brothers and two sisters. He later reported that his first zither was one he found in his grandmother's attic, at the age of 12.

As ordered by his father, he started an apprenticeship as a tool and die maker at the age of 14, while also taking music evening courses at a private institution. He successfully finished his apprenticeship in 1924 and worked in a car factory until being unemployed in January 1925. As he had already begun to study at the University of Music and Performing Arts, Vienna in 1924, he subsequently earned his living as an entertainer in a Heuriger (a wine bar, typically with a garden, usually selling the year's new wine) and soon found himself earning more income than his father. He continued his studies until 1928.

Sviatoslav Teofilovich Richter (Russian: Святослав Теофилович Рихтер Sviatosláv Teofílovich Ríkhter, Russian pronunciation: [svʲjətəsˈlaf tʲɪəˈfʲiləvʲɪtɕ ˈrʲixtər], Ukrainian: Святослав Теофілович Ріхтер; March 20 [O.S. March 7] 1915 – August 1, 1997) was a Soviet pianist well known for the depth of his interpretations, virtuoso technique, and vast repertoire. He is widely considered one of the greatest pianists of the 20th century.

Richter was born in Zhytomyr, Ukraine. His father, Teofil Danilovich Richter (1872–1941), was a German expatriate pianist, organist, and composer who had studied in Vienna. His mother, Anna Pavlovna (née Moskaleva; 1892–1963), was from a landowning Russian family, and at one point had been a pupil of her future husband. In 1918, when Richter's parents were in Odessa, the Civil War separated them from their son, and Richter moved in with his aunt Tamara. He lived with her from 1918 to 1921, and it was then that his interest in art first manifested itself, although he first became interested in painting, which his aunt taught him.

Ludwig van Beethoven (ⁱ/ˈlʊdvɪɡ væn ˈbeɪt.hoʊvən/; German pronunciation: [ˈluːtvɪç fan ˈbeːt.hoːfən] ( listen); baptized 17 December 1770 – 26 March 1827) was a German composer and pianist. A crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential of all composers.

Born in Bonn, then the capital of the Electorate of Cologne and part of the Holy Roman Empire, Beethoven moved to Vienna in his early 20s, studying with Joseph Haydn and quickly gaining a reputation as a virtuoso pianist. His hearing began to deteriorate in his late twenties, yet he continued to compose, conduct, and perform, even after becoming completely deaf.

Beethoven was the grandson of a musician of Flemish origin named Lodewijk van Beethoven (1712–73) who moved at the age of twenty to Bonn. Lodewijk (Ludwig is the German cognate of Dutch Lodewijk) was employed as a bass singer at the court of the Elector of Cologne, eventually rising to become Kapellmeister (music director). Lodewijk had one son, Johann (1740–1792), who worked as a tenor in the same musical establishment, and gave lessons on piano and violin to supplement his income. Johann married Maria Magdalena Keverich in 1767; she was the daughter of Johann Heinrich Keverich, who had been the head chef at the court of the Archbishopric of Trier.
