Abstract
The article is devoted to the last composition of N. Sidelnikov — a novel-sympho- ny for piano solo on motives of ancient Greek myths about Theseus, in five frescoes. This work generalizes the essential features of his thinking and style: philosophical logic, religiosity (the opus was finished in the last days of the composer’s life). The unique concept is embodied in a cyclic composition, peculiar structures (the idea of labyrinth), numerous allusions both on classical music and on previous compositions by Sidelnikov. In the present paper the particular qualities of themes, genre system, dramatic composition and piano texture are discussed.
