The Complex Plane is a two track Bohlen-Pierce guitar rehearsed (and therefore directed) improvisation with backing drums. Click on the graphic above to see the guitar and information on this tuning.

Three by 19 edo

Thursday, July 2nd, 2015


I put a GK-3 hex pick up on my 19 edo guitar – what follows are three demonstration pieces that rely on the pitch interpretation of the GP-10 processor. My overall impression that this was successfully accomplished as you can clear hear places where I pushed a decidedly non-12 equal note(s) through the system.

Distorted harmony in C major (intended to be 12 edo harmony which gets “bent”)

I Play The Wind (aeolian harmonic series guitar, bass, psaltery)

Thursday, November 28th, 2013

Audio Only
I Play The Wind

Using my DIY 23 edo guitar, DIY electric cello, and DIY electric psaltery I recorded the wind playing these instruments after they were tuned in just intonation or harmonic series relationships. Adding to the harmonic series nature of this composition is the fact that the aeolian does not sound the fundamental – so what you hear are only harmonics of the strings. To create this composition I complied about 8 hours of 44.1kHz 24-bit recordings, noise reduced, selected sections and sequenced in Sonar X3. After I finished with the audio I paired it up with time lapse video I took of the sky. Doing this in my spare time, making recordings and processing them into a composition took several days of work.

DIY Harmonic Series 24 – 48 guitar refret

Saturday, July 27th, 2013


I am re-fretting my cable tie guitar into a harmonic series guitar by gluing panacea bright 18 gauge stem wire with super glue to the fretboard. This fretting technique was introduced into my xenharmonic community by Dante Rosati and I first saw it in person at OddMusic CU in the work of Andrew Heathwaite. Some of the frets above are obviously at an angle – this was needed to get the proper pitches. (I was matching a piano tuned to the harmonic series segment.)

Here is an example piece using a soundhole pickup.

DIY 23 edo stick guitar Improvisation

Saturday, June 15th, 2013


I recorded an improvisation with the above DIY 23 edo guitar. The string are tuned in a quasi-normal 12 edo tuning – unison at the 9th fret except for the “B” string which is unison with the “G” string at the 7th fret.

Artificial – drums and izotope stutter edit both driven by a midi extraction of the guitar track.

Au Naturale – as I performed it with just a touch of reverberation.
