7 mouth harmonicas in different tunings (G, A, B, C, D, E, F), button accordion

Written for the 9th Pythian Games of The Pro Arte Foundation and dedicated to Sergei Tchirkov

The piece refers to Sonata of sleep, an unrealized project by Konstantin Melnikov (1929). This plot, sinister enough, was a health resort for sleep treatment, a huge dormitory, where hundreds of people had to sleep healthy and collectively under accompaniment of specially selected, live performed music and sounds of nature. The composition is ghostly monotimbral; its form is built as a serie of asymmetrically nested concentric circles: each type of material is concentrated in its place, and extends back and forth, interacting with other types.
