Realization #82 of an open form work. 

Details for those who want to know *what* they're hearing:

Some unheard but endlessly repeating  rhythmicized tone-row girds each realization of this work.

Any tone-row contains 220 trichords.  Graphed in time and interval space, each trichord  (as a triangle now) has a geometrical (signed) area.  While the area of any one triangle depends on the units chosen for both time and interval width, the ratio of two triangle areas is invariant of the units.  So ordering the 220 trichords by increasing area makes intrinsic sense.  
It also produces a distinct musical effect, you will hear it, suggestive of careful and gradual development.  The reasons why the mathematical strategy has this musical effect are complex and perhaps hard to foresee in advance.

Now transposing the row up a semitone but also forcing all the notes back  into the original octave changes the area of 1/4 of the trichord/triangles. This shuffles the trichord order and produces a kind of variation.  This work, as a whole, proceeds through all 12 of these transposition-derived variations.

Well that describe the timpani part anyway.  

The flute doubles the timpani always at some number of octave, and climbs in register during the stretch of each variation, flute register roughly correlated with trichord/triangle area.  Octave transpositions always apply to all the notes in a trichord in order to preserve the shape, which of course is the chief musical determinant here.

The flute part can be performed alone.  It can also be performed with the timpani part on fixed media.  But live performance of the timpani part would require 12 drums, and perhaps two players, and perhaps some technology for coordination (since the rhythms will be hard to count in the usual way).

If there's interest, I'll upload other realizations.  All realizations are both recognizably "the same piece" yet also reflective of the idiosyncrasies of the basic rhythmicized tone-row.

when the waves of silence break
on the dharma nomad's sitting mind
the daylight sleeper's nagual wakes
for a body of the idle kind

that speaks in riddles, muted rhymes
and labrythene paths of jesting Joyce
where assonance stands guard and chimes
in onomatopoeic trysts

for rivers run and waters foam
and dogs are dogs of many heads
no dwellings last where prospects roam
and liquid hope permits no rest

and the knowledge of the miserly
cannot withstand the yearly flooding force
and can and will and is not allowed to atrophy
as long as eight blurred legs still make a horse

ah burning barnacles to make light
of tonal drylands and bold vertebrates
bridges? yes, bridges burn for ashes' flight
and sparks and bioluminosity and microtonal clefs

for those who walk the open scalar fields
have guns that glow and minds to blow
for those who raft down rapid vector creeks
having dreams to grow and seeds to sow -
