An Example of Generating an Array from a Small Set
I begin with this set: 64170 I want to get a big ugly rectangular block, from which we'll swap
and try to create something more interesting. The set has only 1
major third in it, so transposing it by that interval (twice) (thus
cycling the set through an augmented triad (major third + major third +
major third) gives us lots of new pitches (only 1 duplicate each time).
For each one of those 3 sets, I generate a retrograde form, and
generate an inversion form
that involves no duplicates (inverting 64170 to 35829
generates no duplicates), and generate a retrograde from that. (i.e. an
RI of the original). So I end up with a 12-line
block: then I swap to get 01467 "verticals":

This looks very. . . .um. . ."harmonic" or "vertical", but it could
form the basis of a single line, if you wanted(!) It's all in the
interpretation. For example, it could be for solo violin: the first four
lines could be arco normale in 4 different dynamics; the next 4
lines could be pizz in 4 different dynamics; the next 4 for, say,
molto sul pont in 4 different dynamics.
To make some decent music out of that would be a
challenge, but that's where it gets fun. . . . (Notice, register
and rhythm are not specified at all, so you are free to use your intuition
on those scores. . . )
