Microtonal Computer Music Etude w drums #20

This, my second mixed Trio in poly, features 17-19-21-23-25-28-31 seven note scale in the cello, that loops 6X against two polyrhythmic contrapuntal 24 unequal Pythagorean scale of al Farabi in the piano, and Ben Johnston's 6th Prime row of 25 unequal per octave, in the Clarinet. The interplay is finely thought out and responsorial. The poly trio is a new form I am experimenting with for more transparency for the contrapuntal interplay between the instruments in polymicrotonality. 2025

Mixed Trio in Polytempic Polymicrotonality #2

Twist

This piece is an outgrowth of the previous sextet that is now a NONET, with English Horn, C Trumpet, violin, viola, cello, 2 marimbas, guitar and piano. This is fully polytempic, but is only standard tuned, no microtones. (unless of course 12tet in-itself is already microtuned as it deviates from just overtones) . This piece is sprightly and alive, quite the opposite of its composer, so that remains an enigma. 

Just Shut the Fuck UP, it's a Beautiful Day Outside and I have a Boner, so don't ruin it.

Like a wild Klezmer orchestra, everyone is going dixieland Mad with pdlytempo and polymicrotonality, for piano, guitar, violin, viola, cello, 2 marimbas, English horn and Trumpet. It's a mad drunken bar fight but, fun, a fun mad drinking bar fight. No one lives! Composed today and all week. This is related to the Boner happy day piece. You're welcome. 

Polymicrotonal Nonet I

This music is about how we are all fucked and Trump will destroy the Earth, as I've been fucking telling you idiots for the last ten fucking goddamned years and you just sat on your ass doing nothing. Happy Death. 2025

Nonet in Polytempic 12tet, updated version, for English Horn, Trumpet, Violin, Viola, Cello, two Marimbae, Piano and Guitar

Music for English horn, trumpet, violin, viola, cello, two vibraphones, guitar and piano. Tunings will be discussed later. Working on score, still. This piece is constantly evolving. 2025

Polymicrotonal Nonet, without Polytempo, version 2, for Violin, Viola, Cello, English Horn, Trumpet, 2 Vibraphones, Guitar and Just Piano

Totally synthesized version of nonet for acoustic instruments, all with samplers. Relax and enjoy, or I'll kick your fucking ass. 

Nonet synthesized, Version III

2 Trumpets, Horn in F, Trombone, Tuba in 99-98-97-96-95 ratio tempi relationships with "large" quarter and eighth tone modulations. Quasi tripartite form in a Schoenbergian sense in that there is no tonic-dominant axis for formal constraints, yet the microtonal modulations act in place to delineate form. Simple retrograde is employed to a general singular "diatonic" line multiplied and displaced by the pdlytempo. This is not phase music. This is still polytempo but at micro rhythmic gradations. Each tempo is marked by a .5 beat difference between the five parts. There is no convergence, only separation, like our country. Frankly, like the world today.

Polytempic Polymicrotonal Brass Quintet

If a composer wishes to avoid tonality, wishes to avoid the monarchical tyranny of tonic, then a simple (but not sure-fire) recipe consists in working a symmetrical treatment of the totality of pitches (with said totality often going by the name "total chromatic," or more generally "aggregate," but aggregate can also mean a totality of anything).  The twelve-tone system treats pitch classes symmetrically by design, and aleatoric methods also prove quite effective.  Other tyrants can arise aside from tonics.  So if mezzo-forte, or the central octave, or the 16th-note should threaten domination, a composer can also serialize (or randomize) dynamics, tessitura, or duration, etc.  In practice, all this fair treatment of possibilities, all this fiat symmetry, can ironically make tyrants out of the relevant aggregates themselves, effectively replacing monarchy, one might say, by obsessive bureaucracy, with the ear experiencing concomitant fatigue (not necessarily a bad thing depending on the composer's artistic goal).  In any case the emergence of this irony perhaps explains the briefness for total serialism's vogue.  Long ago, atonal composers working more freely discovered the trick of "keeping a note in your pocket" only to pull it out again when you need it to sound fresh---and it will.  

This piece plies a latter-day total serialism (but a serialism not anchored in rows) which governs pitch, tessitura, rhythm, dynamics and articulation, but which has the note-in-the-pocket wisdom inscribed in its genetics.  The 81 sections survey all 80 hexachord-up-transposition classes (the final section reprising the first, a whole-tone scale), with each section signaled by the entrance of a single pocketed pitch class and less noticeably by the departure of another (so traversing a Hamiltonian circuit through hexachord space).  Likewise, a Hamiltonian circuit through time-point "hexachords" (a la Babbitt) characterizes the rhythm.  But then each hexachord gets developed by a special type of Hamiltonian circuit through all 20 of its own sub-trichords, with the instantiation of each trichord pulling a note of a shallower pocket. 

The spare texture of the present work pays homage to John Cage, specifically works from his Lou Harrison period, to Morton Feldman, specifically his late pattern pieces, to Jo Kondo, specifically his hockets, and to Jonathan Kramer, specifically his process pieces and works with restricted pitch sets.
