Vladimir Deshevov was a key figure in the Russian avant-garde, and this Ballade exhibits the percussive, brittle textures characteristic of his style. It moves away from Romantic sentimentality toward a more fragmented, Modernist approach.
Mastering the non-traditional rhythmic accents and sharp dynamic changes is essential for this piece.
