Instrumentation: flutes nonet. The download includes the score and parts.

The piece is based on a nine-note block that is always observed from a different perspective. At the beginning it is seen as a perfect vertical simultaneity, then turning ninety degrees to become a horizontal succession of pitches that appears on the bass flute. The unison represents the moment in a three dimensions rotation of the block in which all its components remain behind the only visible one, represented by a single note. These procedures continue all through the piece until the climax point where seven piccolos gradually appear to overlap the horizontal line by the two lower flutes. Towards the end the textures become more irrupting to conclude with a choral texture that emerges from the unison.
