The use of musical ideas or themes connected to a specific nation, area, or culture, such as folk melodies and harmonies, rhythms, and chords that are affected by them, is referred to as "nationalistic music."
The early 19th century saw the emergence of nationalism in association with political independence movements. It was distinguished by a focus on national musical characteristics, such as the adoption of nationalist themes for operas, symphonic poems, or other types of music, or by the inclusion of folk songs, dances, or rhythms. Composers started to diverge from the standards established by Italian, French, and especially German traditionalists when new nations in Europe came into being as a protest against the dominance of the European classical legacy.
