This work looks into the context of Eugen Suchoň's works, namely the inspirational relation to the folk ethnic music of Slovakia. My intention was to compare specific compositional approaches in which the author combines the tradition of Western European avant-garde with the style of the Slovak folk song. In this respect, we can see a unique approach to the concept of the Slovak National Opera but also the special style of Eugene Suchoň, in which the folk song has a thematic role. The work deals with Eugen Suchoň's operas, in which he established Slovak national music, which is proven by the categorization of the opera Krútňava as a national Slovak opera. These contexts can eventually transform into new inspiration for the current generation of composers.
