from the 'Bicinium sul primo modo' by Gioseffo Zarlino (1517 – 1590)
Verdichtung (in German thickening, compaction) is a piece for five instruments (flute, clarinet in Bb, violin, cello, piano), which draws its lifeblood from the search for a new way to relocate notes in an arbitrary way and redefine in a new perspective is the spaces delimited by the theoretical grids postulated by the great 16th-century mathematician and musician.
During the generation of musical material, sonorities and chordal relationships have been obtained and elaborated by a complex system of algorithms realized within the Max-Msp development environment, starting from the calculation of the frequencies and the arbitrary subdivision of the interval spaces. The generated material was then subjected to a profound musical and aesthetic reflection before finally being transcribed in the score and again elaborated.
This relocation gives rise to new sounds, with the chords melting and re-thickening into new elements through the massive use of glissatis and microtonality, limited to the quarter tone. Thus, sound objects are recreated outside the hue and temperament, to such an extent that the piano, the only tempered instrument, seems at times prepared and out of tune.
