Triptych Sofa
The Triptych sofa forms part of an interdisciplinary art concept based on Pierre Boulez’ serial music composition - Structure 1a for two pianos (1951).
The Triptych is designed to stand free of the wall, as far as the sides and the back represent Boulez’ music composition in form of a vertical-horizontal system. The verticals indicate the 14 sections; the horizontals indicate the polyphonic structure in form of an alternating number of tubes/voices (1 - 6; one tube represents one 12-tone series). By this we have a sequence going clockwise, which, in its entirety, corresponds with the amount of time it takes to play Structure 1a in its full length - 205 seconds (15cm = 10sec).
The cushions behind the vertical-horizontal system are divided into two horizontal layers, representing the part played by each of the two pianists (Piano I: upper part/ Piano II: lower part). At the vertical distinction between Section V and Section VI, the two colours are reversed, pointing out the central axis, where all the tone series employed in the first part of the music composition become retrograde.
MWS-1a
Modular Wall Structure 1a (MWS-1a) is a CD-storage system representing the Transposition Matrices with which Pierre Boulez composed his Structures 1a. Each cube represents one particular note in form of a CD-package arrangement expressing the four basic parameters - pitch, duration, dynamic and attack.
