Romantic composers used many folk songs in their nationalistic music.
Explanation:
Music is an efficient instrument for spreading nationalist ideals. Many composers have used the melodies and rhythms of their country's folklore, seeking inspiration from the legends and stories of their people. Created compositions with strong epic and patriotic content.
Example: The Polish Frederic Chopin (1810-1849) is an example of nationalist sentiment in music. At the time, his homeland, Poland was under the control of the Russian tsar, and Chopin shared the nationalists' desire to liberate the country. He was residing in Vienna when word of the insurrection in Warsaw came to him. Enthusiastic, Chopin improvised in front of an attentive and moving audience, the Revolutionary Study, at whose breakneck pace he represented Poland's struggle for liberation. Other compositions extolling Poland also became classics like Polish No. 3 and Polish No. 53, nicknamed "Heroic."
They used a lot of national legends to portray stories and lots of tunes of dances and music from their homelands as well as folk songs that were part of their culture.
