for centurys, western music has been determined by the grid of the circle of fifths, establishing a virtual tonal space of 12 equidistant
pitches, projected onto a circle similar to a clock dial.
with a special filter algorithm, recordings of music are separated into the 12 pitchclasses (a pitchclass means e.g. all "c"s across several octaves).
the 12 resulting tracks contain one pitchclass each, spread over the full orchestral range.
they are projected thru an array of 12 loudspeakers, arranged in
the order of the circle of fifths.
the virtual space of tonal order
is thus projected into the real space of loudspeakers.
depending
on the postion of the listener, he either hears the original piece (=
equal distance to all speakers) or, to the other extreme, one
pitchclass (= ear close to only one speaker) only. between those two extremes lies a world of subtle to gross shifts in the perception of the music.
hear a simulation, based on the menuet from w.a. mozart´s jupiter symphony (mp3)
