In the 20th Century, as new song forms emerged worldwide, including genres like jazz, rock, and pop, the classical art song of the 19th Century gradually lost popularity. A singer, a piano, poems of love and death, and a romantic tonal language: the leading art form of the bourgeois salon increasingly became a musical niche for lovers and aficionados. The heyday of the European art song, which began in the middle of the 18th century, came to an end at the beginning of the 20th century.

However, composers Béla Bartók and Zoltán Kodály took a different path: they renewed the art song by returning it to its folk origins. The most fascinating aspect of their work was not just their painstaking ethnomusicological field research. While they preserved Hungarian folk music, recording (as best they could at the time) and notating this music, they also allowed it to inspire their own compositions.

At a time when many musicians appropriated folk music for political reasons, Bartók and Kodály created genuine folk art that did not pander or simplify, but spoke of feelings that directly touched its listeners.
