für orgel und eine(n) tonsetzer(in) ...2003...
for mauser (1932 - 2006)
what do you do, if you work with just intonation and wish to write a
piece for organ?
you have to deal with the relation between equally tempered and over-
or undertonal (just) intonation.
2001 i had several opportunities to make a study of some wonderful
this eventually put me on the path towards this composition.
in this piece only those frequencies of the organ sound that have close
to whole-numbered ratios
(+/- 6 cents) to a fundamental (in this case C’ at about 32
because the frequencies are never perfectly tuned - a result of the
organ’s tempered tuning - more or less strong beatings and
frictions emerge, that rhythmically and timbrally shape the inner life
of the sounds.
a realisation of this piece strongly depends on the disposition of the
instrument and the performance space.
the version at hand corresponds approximately to the first performance
by eva-maria houben at
st. suitbertus church, dortmund october 3, 2003.
for this cd i tried to record the organ in such a way that the
playback, instead of reproducing the church environment, projects the
instrument into the listener’s space.
