These three pieces, while sharing the characteristic of lacking clear tonality, each embody distinct concepts.

• Fragment of Three Notes: This is an improvisational miniature that flowed spontaneously from the fingers. The three-note motif introduced at the beginning is repeated and transformed, forming the structural backbone of the piece.
• Ostinato: Common elements are repeated in arpeggios, drones, and bass lines, with the aim of evoking a sense of continuity and exhilaration.
• Water Reflection: This piece employs a twelve-tone row to depict images reflected on the water surface, the appearance of ripples, and inorganic qualities, among other elements.
