EXPASSVM in Latin means “unfold”, but creates a false cognate with “space”, and the relation between these two ideas anticipates one of the interests of the piece. The spatial unfolding displayed initially with circular movement of a sound counter-places itself to its spectrum (embedded origin). Frequency bands extracted from this spectrum are defined to outstand certain non-audible characteristics in the sound as a whole and polarizes note groups which will constitute the harmonious “sense” of the piece. The long initial “timbre-harmony” sounds acquire a new dimension that striates the time creating the pulse and turning it polyrythm. The polyrythm splits in two at its extremes creating the dialectical relationship between corpuscular sounds, originated by pulses, and the “timbre-harmony” sounds (absent origin). Therefore, the “unfolding” ingrains itself, during the totality of the piece, in its simultaneity as well as in the succession. The piece was co-realized at the home-studio of the composer in Campinas.
