Mykola Leontovych
Mykola Leontovych specialised in a cappella choral music. He is remembered today mostly through the musical works he left behind, which include over 150 choral compositions. These range from artistic arrangements of folk songs, religious works (including his liturgy), cantatas, and choral compositions set to the words of various Ukrainian poets. His two most famous works are the choral miniatures "Schedryk" and "Dudaryk".
Opera
In Russian Eastern Europe, several national operas began to emerge. Ukrainian opera was developed by Semen Hulak-Artemovsky (1813–1873) whose most famous work "Zaporozhets za Dunayem" (A Cossack Beyond the Danube) is regularly performed around the world. Other Ukrainian opera composers include Mykola Lysenko ("Taras Bulba" and "Natalka Poltavka"), Heorhiy Maiboroda, and Yuliy Meitus. At the turn of the century, a distinct national opera movement also began to emerge in Georgia under the leadership Zacharia Paliashvili, who fused local folk songs and stories with 19th-century Romantic classical themes.
The key figure of Hungarian national opera in the 19th century was Ferenc Erkel, whose works mostly dealt with historical themes. Among his most often performed operas are "Hunyadi László" and "Bánk bán". The most famous modern Hungarian opera is Béla Bartók's "Duke Bluebeard's Castle".
