Rotomotor, subtitled “ein motorische Idiotikon”, is a 28 minutes long reading representing one of Bruhin's major works. Written in Zurich between 1976 and 1977, then recorded in August 1978 at Etienne Conod’s Sunrise Studio. Rotomotor is a poetic Idiotikon of the swiss-german dialect where, instead of the straight alphabetical order, the words are organized according to the similarities of their letters (each word differ from the previous one by just one letter). For this reading a delay equipment which repeated the signal after 0.6 seconds was used and each word is superimposed to the echo of the preceding one. On one hand this echo generates the rhythm of the performance, on the other it supports the acoustic metamorphosis of the words. Again, a very simple concept perfectly accomplished.
