I have finally released my album “A Figure in a Field”. It is a mostly ambient leaning album in many tunings and created with many techniques. See the album and track notes for details.

Its a Queer Time (a microtonal setting of a Robert Graves poem)

Tuesday, April 19th, 2016

Its a Queer Time, a setting of a poem written by Robert Graves and read by Pete Marchetto from librivox tuned in 22 edo, 11 edo, and 43 JI running on 8 different synths. The technology behind the audio is using Gestrument as a performance controller and transmitting its midi output over ethernet using rtpMIDI (thank you Tobias!!) as a Windows surrogate for Apple Bonjour – the end result is that I play the Gestrument on my iPad and Sonar sees the midi from it as a virtual midi controller. Then it is simply a matter of routing each midi channel to separate tracks each with a microtonal aware synthesizer [panned a bit uniquely] – the audio was then added, the midi tracks trimmed appropriately and then married to the video. Since the video and Librivox licenses are public domain by necessity my musical setting of these resources is public domain as well.

For Quincas Moriera – the long version of the music.

  • If an enemy should threaten to attack the United States, you would not be alone.
  • The entire Nation would be mobilizing to repulse the attack, destroy the enemy, and hold down our own loss of life.
  • Much assistance would be available to you–from local, State and Federal governments, from the U.S. armed forces units in your area, and from your neighbors and fellow-Americans.
  • 11 edo Piano Improvisation

    Monday, July 28th, 2014


    11 edo Piano Improvisation is built around a very simple motive of a descending 11 edo “half” steps. The only unusual aspect of this piece is the use of repeating a note to fill out 11 edo to 12 steps which does wonders for playability on a regular keyboard. This would more apparent if my playing wasn’t so sloppy but it was cathartic for me. Hopefully some of that drama comes across, if not you’ll probably consider this pretty boring.

    Dream Land

    Dream Land is an electronic composition in 11 edo and includes 3 instances of Z3TA+ 2.1, Kontakt orchestral percussion and Jerome McGann reciting Edgar Allen Poe’s poem Dream-Land taken from a recording found at

    Walk a Clear Path

    Saturday, May 25th, 2013


    Walk a Clear Path is a derivative piece created by taking 18 tracks from the 5/24/2013 event, extracting midi pitches & velocity, manipulating the midi data, and assigning each of the 18 tracks to an instance of absynth 5 tuned to 11 edo.

    Each instance of absynth had a different patch tweaked or mutated in some fashion. I also used Sonar’s tempo programing ability to manipulate the temporal execution of the midi data.

  • Not the one that appears every two or three years –
    the one that appears once in forty-four years.

    Not the one that is full for a single night –
    the one that is full every night it is in the sky.

    Not the one on which to see a man or a rabbit –
    the one on which there are branches and leaves in silhouette.

    Not the one that is drowned out by a glowing city –
    the one that is as bright above a city as it is where the sky is darkest.

    Not the one by which you might read a newspaper headline –
    the one by which you can read what had been invisible.

    Not the one whose name is part of a figure of speech –
    the one that asks us to say something new.

    Not the one that rhymes with hue and shoe and June and spoon –
    the one that rhymes with night and weight and hold and hope.

    Blue Moon, Blue Moon, Blue Moon
    And hope Blue Moon, Blue Moon, Blue Moon

  • The Broken Cathedral of Christchurch

    Monday, May 13th, 2013

    The Broken Cathedral of Christchurch is an ambient poly-tuning piece using 11, 12, and 19 notes to the octave. The instruments used are a Korg MS2000 synthesizer, 19 edo electric guitar (several tracks), and 5 string bass – all with liberal application of effects, mixing, and mastering. The piece is dedicated to the Anglican cathedral of Christchurch New Zealand which will be brought down and rebuilt due to extensive earthquake damage.

    This is a repost because the original post was damaged.

    I Love You, Cyanobacteria

    Friday, May 3rd, 2013


    I Love You, Cyanobacteria is a electropop song in 11 edo that acknowledges our debt to cyanobacteria. This is a multi-track recording of my Korg MS2000 with a 12 note user tuning – I doubled Bb and B to get 11 edo which increments about 9 cents extra per note to reach the octave. The drums were run off of the arpeggiator but as you can hear everything else was played. My voice is vocoded.
