Eye floaters (Glaskörpertrübungen) are small dark shapes that float across the field of vision. Tiny strands of the vitreous (the gel-like fluid that fills the eye) stick together and cast shadows on the retina (the light-sensitive layer of tissue at the back of the eye). Those shadows appear as floating spots or threads, and follow the motion of the eye with a small “delay”.  I started noticing quite visible threads and a medium-large black spot on my left eye while writing the piece, and this constant presence ended up having a central role in the concept of the composition. The “mouches volantes” (fliegende Mücken) offered me everchanging examples of layering (between opaque and transparent elements), and patterns of delayed motion, that I tried to explore in microtonal textures across the soprano saxophone, the accordion, and a set of percussions composed of Almglocken, non tempered-Cencerros, Japanese rins, small gongs and bells.
