This piece by Shigeru Kan-no explores modern Japanese musical idioms through a Western piano lens, emphasizing minimalist textures. It is highly idiosyncratic, utilizing sparse intervals to create a sense of vast space.
The main challenge is controlling the decay of sound to create the stark, architectural silence required by the composition.
