Ulrich Seidel
Thomas M. J. Schäfer composed a permutative canon for 3 voices, 30
bars and 300 seconds. The graphical score has the form of an
equilateral triangle. The canon theme consists of 10 bars. The three
voices have to pause sometimes for one or more bars when the theme
was played. The beginning tonality is shifted, the permutations lead
to dissonances and modern impression. Baroque and modern spirit are
linked by romantic phrasing. The canon refers to the name, the
oeuvre and the contrapuntal execution of J. S. Bach.
