Based on a mediaeval logic machine that can even “prove” God, musikprotokoll builds an interactive sound installation at Kunsthaus. Vokalensemble NOVA deploys the Llullophone in order to marry very old with very new music.

“Die Logik der Engel” is distant vocal music from the 13th and 14th century, is miniature premieres from the here and now in a cabinet of mirrors. The basis of this fascinating journey back in time with six male voices, is an idea devised by Majorcan philosopher and theologian Ramon Llull who died 700 years ago. In his book “Ars magna” Llull describes a logic machine said to be able to distinguish between truth and lie. By rotating three mechanical disks, it was possible to combine concepts so as to form sentences supposed to serve as proof of God. Mathematicians and philosophers such as G.W. Leibniz (1646–1716) made reference to Llull’s logic machine, and modern computer science sees it as an early “generative system”, a precursor to modern computer systems based on algorithms.  The concert version will be staged at the Helmut List Halle by Vokalensemble NOVA, who specialise in very, very old and new music.
