Document 5: Pietro Mascagni: Pietro Antonio Stefano Mascagni (] ; 7 December 1863 – 2 August 1945) was an Italian composer most noted for his operas. His 1890 masterpiece "Cavalleria Rusticana" caused one of the greatest sensations in opera history and single-handedly ushered in the "Verismo" movement in Italian dramatic music. While it was often held that Mascagni, like Leoncavallo, was a "one-opera man" who could never repeat his first success, "L'amico Fritz" and "Iris" have remained in the repertoire in Europe (especially Italy) since their premieres. Mascagni said that at one point, "Iris" was performed in Italy more often than "Cavalleria" (cf. Stivender).
Document 6: Antonín Dvořák: 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."

Dvořák's 5th, 7th and 11th Slavonic Dances are in the form of the skočná.
Document 14: My Home (Dvořák): My Home (Czech: "Domov můj, předehra ke hře F. F. Šamberka" ), Op. 62, B. 125a, is an overture in C major by Czech composer Antonín Dvořák. The overture was composed from December 1881 to January 23, 1882 as one of nine numbers comprising the incidental music for the play "Josef Kajetán Tyl" by František Ferdinand Šamberk. Dvořák constructed the music in sonata form on two song themes associated with the play's protagonist, Czech dramatist Josef Kajetán Tyl: ""Kde domov můj?"" by František Škroup, and the folk tune ""Na tom našem dvoře"". Škroup composed ""Kde domov můj?"" ("Where is my home?") in 1834 to a text written by Tyl. The song quickly became popular and was later designated as the Czech national anthem. ""Na tom našem dvoře"" was a song sung in productions of "Strakonický dudák" (The Bagpiper of Strakonice), one of Tyl's most popular plays. The overture is largely performed separately as a concert work, usually lasting about ten minutes. Many conductors have conducted this piece including Jan Kučera, Bohumil Gregor and Karel Ančerl.

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.
