divided west and (equally) is an exploration of the
possibility of travelling through pitch- and time- space either by
means of equally distanced steps or by means of proportional divisions,
the premiss being that these two types of division represent two
essentially different types of hearing.

The intervals of the octave , fifth and fourth are each divided into
scales of 5, 3 (6) and 7 equal steps which along with the tempered
chromatic scale provide the 10 equal distance scales hat underly the
piece. (The rhythmical structure is in principle a mirror of the pitch
grid although transformations are effected by mapping the "speed" of
one scale onto another.)
The live piano plays a double role of on the one hand taking part in
the process of exchanging equal division scales (of the ten available
scales the live piano is only capable of playing two - the chromatic
and whole tone scales) and on the other that of "interpreting" melodies
that result from the interaction of the various equal distance scales
in terms of proportions.
A midi piano module tuned so as to be able to play the various equal
distance scales is played through two loudspeakers placed inside the
