The Chord Catalogue
all the 8178 chords possible in one octave
Extreme and, one would think, extremely simple.
A lesser man would have arranged those 8178 chords in some symphonically
meaningful, or else quasi-random order, but Johnson proceeded methodically
up the chromatic scale from two notes at a time, three, four, so on to 13.
Before each section he would disconcertingly inform us, "the 715 four-note
chords... the 1287 five-note chords..." His modest promise that we
would "get the idea of the piece" within a few minutes wasn't
really true. Two-note chords were predictably dull, three-note ones little
better.But four notes began to sound almost like functional tonality in
this denuded context: five sounded noticeagbly lusher, and reminded one
of the era in which harmony was enriched by ninth chords and similar possibilities.
By the time we reached 10-note chords, the information overload was such
that differences were hardly perceptible, a situation reminiscent of serial
music. Far from being heavy-handed minimalism, the Chord Catalogue was
a pointed lesson in musi!c history and the relativity of perception.

Another transcendental experience was Tom
Johnson's Chord Catalogue, which included all the 8178 chords possible
in the octave c - c1, from the two-note chords to the complete cluster.
Johnson, who required only one hour for this, is the only pianist who can
make his way through the dizzying multiplicity of colors present in the
equal-tempered scale. Resonances in the space, and excitations in the ears,
caused sheer psychedelic perceptions, that well surpassed the simple combinations
