Input (English): Context_1 : Moravian Duets (in Czech: "Moravské dvojzpěvy" ) by Antonín Dvořák is a cycle of 23 Moravian folk poetry settings for two voices with piano accompaniment, composed between 1875 and 1881. The Duets, published in three volumes, Op. 20 (B. 50), Op. 32 (B. 60 and 62), and Op. 38 (B. 69), occupy an important position among Dvořák's other works. The fifteen duets of Op. 32 are the most famous part of the cycle. Popular interest in the "Moravian Duets" was the starting point for subsequent works which propelled Dvořák to international fame. Context_2 : Alfred is a heroic opera in three acts by the Czech composer Antonín Dvořák. It was Dvořák's first opera and the only one he composed to a German text. The libretto, by Carl Theodor Körner, had already been set by Friedrich von Flotow (as "Alfred der Große") and is based on the story of the English king Alfred the Great. Composed in 1870, "Alfred" was never performed during Dvořák's lifetime. It received its premiere (in Czech translation) at the City Theatre, Olomouc on 10 December 1938. Context_3 : The Sonatina in G major for violin and piano (), Op. 100, B. 183, was written by Antonín Dvořák between November 19 and December 3, 1893, in New York City. It was the last chamber composition he wrote during his sojourn in America. Dvořák catered the sonatina to the gradually developing musical abilities of his children, especially those of his 15-year-old daughter Ottilie and 10-year-old son Toník. In a letter to Fritz Simrock on January 2, 1894, Dvořák conceived the piece in the following terms: ""It is intended for youths (dedicated to my two children), but even grown-ups, adults, should be able to converse with it..."" Context_4 : The Antonín Dvořák Museum in Prague is a museum dedicated to the great Czech composer Antonín Dvořák (1841-1904). Context_5 : The Jacobin ("Jakobín" in Czech) is an opera in three acts by Antonín Dvořák to an original Czech libretto by Marie Červinková-Riegrová. Červinková-Riegrová took some of the story's characters from the story by Alois Jirásek, "At the Ducal Court", but devised her own plot about them. The first performance was at the National Theatre, Prague, 1889. Červinková-Riegrová revised the libretto, with Dvořák's permission, in 1894, notably in the last act. Dvořák himself revised the music in 1897 (the revised premiere was on 19 June 1898, under Adolf Čech). Context_6 : Giacomo Antonio Domenico Michele Secondo Maria Puccini (] ; 22 December 1858 29 November 1924) was an Italian opera composer who has been called "the greatest composer of Italian opera after Verdi". Context_7 : The Concerto for Piano and Orchestra in G minor, Op. 33, is the only piano concerto by Czech composer Antonín Dvořák. Written in 1876, it was the first of three concertos that Dvořák completed, followed by the Violin Concerto, Op. 53 from 1879 and the Cello Concerto, Op. 104, written in 1894–1895. The piano concerto is probably the least known and least performed of Dvořák's concertos. Context_8 : Antonín Leopold Dvořák ( ; ] ; 8 September 1841 – 1 May 1904) was a Czech composer. After Bedřich Smetana, he was the second Czech composer to achieve worldwide recognition. Following Smetana's nationalist example, Dvořák frequently employed aspects, specifically rhythms, of the folk music of Moravia and his native Bohemia. Dvořák's own style has been described as "the fullest recreation of a national idiom with that of the symphonic tradition, absorbing folk influences and finding effective ways of using them." Context_9 : The Tragic Overture, B. 16a (also called the Dramatic Overture; Czech: Tragická ouvertura or Dramatická ouvertura ) is an orchestral composition written in 1870 by the Czech composer Antonín Dvořák. It was Dvořák's overture to his first, never published, opera "Alfred". Context_10 : The String Quartet No. 14 in A-flat major, op. 105, B. 193, was the last string quartet completed by Antonín Dvořák, even though it was published before his Thirteenth Quartet (which appeared with the higher opus number 106). Dvořák finished his Fourteenth Quartet in 1895, when he had returned to Bohemia after his visit to America. The gestation of the Quartet had actually begun in America and lasted six months, which was rather protracted for the composer. This Quartet marked an important point in Dvořák's development because he would devote himself almost exclusively to writing explicit program music, namely symphonic poems and operas, afterwards. fact_1 : Antonín Leopold Dvořák ( ; ] ; 8 September 1841 – 1 May 1904) was a Czech composer. fact_2 : Giacomo Antonio Domenico Michele Secondo Maria Puccini (] ; 22 December 1858 29 November 1924) was an Italian opera composer who has been called "the greatest composer of Italian opera after Verdi".
