The aim of this article is to present the possibility of adapting the category of melancholy to the analysis of the word (poetic) and musical works. In the first part, different definitions of melancholy created by philosophers and cultural researchers are taken into consideration. Then I try to interpret the word and musical layers of the poem (and the song) called Crépuscule du soir mystique in the light of solutions typical for melancholic moods. In the last part of the article, I propose to extract a separate expressive category, which will be helpful to analyze pieces from the circle of symbolism in particular.
