A nocturne (from the French which meant nocturnal, from Latin nocturnus) is usually a musical composition that is inspired by, or evocative of, the night. Historically, nocturne is a very old term applied to night Offices and, since the Middle Ages, to divisions in the canonical hour of Matins.

The name nocturne was first applied to pieces in the 18th century, when it indicated an ensemble piece in several movements, normally played for an evening party and then laid aside. Sometimes it carried the Italian equivalent, notturno, such as Wolfgang Amadeus Mozart's quadraphonic Notturno in D, K.286, written for four lightly echoing separated ensembles of paired horns with strings, and his Serenata Notturna, K. 239. At this time, the piece was not necessarily evocative of the night, but might merely be intended for performance at night, much like a serenade.

Vladimir Davidovich Ashkenazy (Russian: Владимир Давидович Ашкенази, Vladimir Davidovič Aškenazi; born July 6, 1937) is a Russian-Icelandic conductor and pianist. Since 1972 he has been a citizen of Iceland, his wife Þórunn's country of birth. Since 1978, because of his many obligations in Europe, he and his family have resided in Meggen, near Lucerne in Switzerland. He is currently Principal Conductor and Artistic Advisor of the Sydney Symphony Orchestra.

Ashkenazy was born in Gorky, Soviet Union (now Nizhny Novgorod, Russia), to the pianist and composer David Ashkenazi and to the actress Yevstolia Grigorievna, born Plotnova. His father was Jewish and his mother was the daughter of a family of Russian Orthodox peasants. He began playing piano at the age of six and, showing prodigious talent, was accepted to the Central Music School at age eight studying with Anaida Sumbatyan. Ashkenazy went on to graduate from the Moscow Conservatory where he studied with Lev Oborin and Boris Zemliansky, winning second prize in the International Chopin Piano Competition in Warsaw in 1955 and the first prize in the Queen Elisabeth Music Competition in Brussels in 1956. He shared the first prize in the 1962 International Tchaikovsky Competition with British pianist John Ogdon. As a student, like many in that period, he was harassed by the KGB to become an "informer." He did not really cooperate, and despite pressures from the authorities, in 1961 married the Iceland-born Þórunn Jóhannsdóttir, who studied piano at the Moscow Conservatory. To marry Ashkenazy, Þórunn was forced to give up her Icelandic citizenship and declare that she wanted to live in the USSR.

Arthur Rubinstein (January 28, 1887 – December 20, 1982) was a Polish-American classical pianist who received international acclaim for his performances of the music written by a variety of composers; many regard him as the greatest Chopin interpreter of his time. He is widely considered one of the greatest classical pianists of the twentieth century.

Rubinstein was born in Łódź, Congress Poland (part of the Russian Empire for the entire time Rubinstein resided there) on January 28, 1887, to a family of assimilated Jews. He was the youngest of eight children, and his father was a wealthy factory owner.

Rubinstein's birth name was Artur Rubinstein, although in English-speaking countries, he preferred to be known as Arthur Rubinstein. However, his United States impresario Sol Hurok insisted he be billed as Artur, and records were released in the West under both versions of his name.

At the age of two, Rubinstein demonstrated perfect pitch and a fascination with the piano, watching his elder sister's piano lessons. By the age of four, he was recognised as a child prodigy. Rubinstein first studied piano in Warsaw. His early piano training came from Karl Heinrich Barth.

Frédéric François Chopin ( /ˈʃoʊpæn/; French pronunciation: [fʁe.de.ʁik ʃɔ.pɛ̃]; Polish: Fryderyk Franciszek Chopin, also phonetically Szopen; 22 February or 1 March 1810 – 17 October 1849) was a Polish composer and virtuoso pianist of French-Polish parentage. He is considered one of the great masters of Romantic music. Chopin was born in Żelazowa Wola, a village in the Duchy of Warsaw. A renowned child-prodigy pianist and composer, Chopin grew up in Warsaw and completed his music education there; he composed many mature works in Warsaw before leaving Poland in 1830 at age 20, shortly before the November 1830 Uprising.

Following the Russian suppression of the Uprising, he settled in Paris as part of Poland's Great Emigration. During the remaining 19 years of his life, Chopin gave only some 30 public performances, preferring the more intimate atmosphere of the salon; he supported himself by sales of his compositions and as a piano teacher. After some romantic dalliances with Polish women, including an abortive engagement, from 1837 to 1847 he carried on a relationship with the French writer Amantine Dupin (pen name "George Sand"). For most of his life, Chopin suffered from poor health; he died in Paris in 1849 at age 39.
