polymicrotonal weirdness with max msp, 2018

PolymicroEtude7

This is a rearrangement and strict parallel chordal enhancement of string quartet 5, with 2 violins, viola, and piano slightly detuned in areas with 14tet, but not much. I'm still trying to find decent string samples. These are from SINE and the piano is Apple's Logic DLS keyboard sample. Composed initially in 2017, redux September 2025

SQ5 as Piano Quartet (alternate version)

Fresh new Etude in new software, vst, controllers, synthesis, etc. Brooding over Trump cuts...preparing to die a la Beaudelaire Rimbaud. Despair ennui and death. 

Etude #50

This quartet is polymicrotonal with tuning systems: 17:19:21:23:25:28:31 in first violin; Arabic 12-tone Pythagorean in second violin; 7-limit tritone in viola; and 19/53tet in cello. The synth is 12tet, so it's actually a five-part poly piece rather than my standard 4 parts. The tempi are in loops and are in the ratios: 
10.25:3.25:6:23:4.25, for v1, v2, viola, cello, and synth, respectively. No score yet, coming soon. 2025.

The seventeenth incarnation of the string quartet series will be a small collection of short Polytempic polymicrotonal pieces with or without additional synth or other instruments. This piece is therefore a Synth Quintet; however, I view the synth part as an "equal democratic" participant and not a soloist.

Another snippet from Caligo Paean - beware of gifts when chasing gods : ) 

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.



Caligo Paean (A gift, a choice)

This is the mixed trio with bassoon added: Clarinet, Bassoon, Cello, and Piano. No fireworks. Just a rather nice low key ensemble. Neither morbid nor jubilant. This is the sister piece to the trio and Polymicrotonal Quartet. My pieces will have several versions. Actually they frankly always did, but it's much more deliberate now. 2025

Mixed Quartet in 12tet

A polycyclic piece with 5 looping cyclic parts not in a neat order, but not polytempic nor polymetric, either. Formerly a string quartet, but with added synth, is essentially a quintet. 2025

String Quintet in standard tuning with synth pad

Tunings are: five sets of differently tuned 17-19-21-23-25-28-31 overtones for piano, violin, marimba, trumpet and English horn, and 48tet for the guitar.

Polytempic Polymicrotonal Sextet for Piano, Violin, Marimba, English Horn, Trumpet in C, and 12-string Guitar

fucked up mess

Twist

The Two Part Inventions for violin I posted recently surely fall beyond the capabilities of a single human performer, I fear.

So I've reconceived the pieces as duos in hocket.  Two violins could achieve my original intention, but why not some timbral contrast as here.

See the previous program notes for details about the construction of the pieces.
