In 1974, Robert Morris and Daniel Starr famously enumerated every all-interval twelve-tone row. 

Inspired by their work, and in around 1979 in unpublished works, I generated an analogous catalog of what one might call the all-trichord rows, meaning rows, which together with two of their untransposed rotations, and in "first-species counterpoint," produce a sequence of all twelve distinct trichord classes.  By the standards of the day, this 
involved very substantial computational search.  But lately I have vastly expanded that calculation, now allowing transposition, retrograde and inversion of the rotations. Some of these new rows provide the basis of my recent pieces.   

The catalog of all-trichord rows runs to about 300 more or less, depending upon the accounting for symmetries.  That makes these rows quite rare among all the twelve-tone rows.  This rarity suggests my original compositional conception but unrealized at the time: a museum-like installation where a listener might walk in a large space from sonic exhibit to sonic exhibit, and experience the different ways these rows fit together and do their thing.  

So here are just three typical exhibits, realized now as works for chamber orchestra.  In each, the basic row first gets a plain but lapidary statement, and then the rotated forms fade in, statistically speaking, and eventually the rows likewise fade out in the order in which they entered, leaving finally a statement of the basic row.  By design, this treatment could loop seamlessly as one "display," as per my original conception.

a small snippet of a live performance by the Intonarumori Trio at the opening of When The Fog Clears as part of The Ten Days On The Island Festival. This was the exhibition where i got to exhibit Caligo Paean, so a big evening for me......more about the trio here

Formed in 2018, The Intonarumori Trio is Danielle Kirby, Mat Ward and Dylan Banks. All three are Hobart based artists whose individual professional practices all span 20 plus years. They have diverse artistic backgrounds that include painting, instrument and theatre design, installation, classical music, noise- art, graphic design and academic research. They have all exhibited, published and performed extensively across Australia as well as undertaken international art-based residencies.  

The trio explore the more occult-centric aspects of Russolo’s practice, approaching performances as a ritualistic space to play with the idea of connection and communication beyond the human realm. 

Russolo believed, and pursued the idea that noise could be used as a bridge to spiritual understanding. He sought to congure and transform energy through the Intonarumori’s ability to ‘spiritualise’ noise. 

Performances by the Trio are pure improvisation, allowing the space and the air to guide the players.

Another snippet from Caligo Paean -

Caligo Paean is a 1 hour long sound piece installed on river front property in the town of Franklin, Tasmania as part of the exhibition "When The Fog Clears". It formed part of the Ten Days on The Island Festival March 2025.
The work was installed in several locations across the property including a stack of subs under an old bus, in the main exhibition space and in an abandoned shed some 40 metres from the main area . The speakers were 'tuned' quite differently depending on their location and the sound was not delay corrected with the result of each mini-installation merging with each other in odd sonic ways - kind of calling the listener from one spot to another. The the work features field recordings, percussion, piano, bass guitar and Intonarumori as well as this special one off choir : )

Caligo is the Ancient goddess of Chaos. Born of the fog she controls the darkness, dwells in the void and is as old as the primordial matter that created the universe. This work is a tribute to the goddess as she continues to influence our lives and, in the case of this installation, the site and concept informing the show.

Official press release below for The Fog Clears

Every day, the mists of the Huon Valley perform a seductive dance, gently obscuring and revealing contours of the fertile land and waters. Situated in The Watershed Franklin, When The Fog Clears features six artists from lutruwita / Tasmania exploring the region’s iconic mists through a variety of mediums including installation, sculpture, illustration, sound, and video.

Developed exclusively for Franklin, this exhibit extends from the waterfront itself into the chambers, kilns, and rafters of the shed, inviting visitors to consider fog as an atmosphere that can cloak us in unexpected ways.

A Hopeless Day in Vain I Search for Meaning and There IS NONE, Whatsoever

a guitar track in 24/60 tet played lightly with tenderness. 2025

solo microtonal guitar #1

A 12/8 Africanesque rhythm with Guitar in unequal 24/octave tuning and Viola in a heptatonic unequal overtone tuning. Both stringed instruments are in a 5:4 ratio with the rhythm . 2025. Scoreless, as most etudes of Poly are.

A piece in 5/4 with two tunings: 12tet and 22/octave Shruti, with pure 25 cents enharmonic tone differences, and Maschine in standard 12tet and modal, with jazz feel drums external to that, playing over the sequenced Maschine .  Thanksgiving Eve, 2025

Polytempic Polymicrotonal ECM fusion w Maschine, Drums, and Microtonal Piano

Three tempi collide in this Thanksgiving Day Parade War Zone Fuck You piece, with Circuit Rhythm patterns in one tempo, sped up and slowed down, and added fx, with a faster template of the midi pattern in another Logic Drumset, with Pianoteq piano in Carlos Alpha 16 note octave tuning played by drum controllers, both Maschine and the KAT pad system. Polytempic Polymicrotonal (two tuning systems) and mass geopolitical war and confusion causing contusions on this illusion of reality, which sucks like no other period in history. Maybe except the holocaust, which is coming, again. And again and again and again, echo......echo............
