19 edo Hex Fuzz Demonstration

Saturday, September 10th, 2016

img_2142-crop Picture by Chris Vaisvil

One Happy Spider (who caught a cicada) is an extended 19 edo guitar improvisation presented in 2 formats for you to compare.

This version is with a “hex fuzz” – distortion added to each string separately which eliminates the cross-string modulation artifacts that occurs when using a conventional guitar pickup and pedal. This was accomplished by using a GK-3 hex pickup on my 19 edo guitar and running it through my Boss GP-10 which has a “poly” (read hex) distortion setting.

This version includes the normal pickup signal run through Guitar Rig in parallel with the hex fuzz version. This is probably the version you want to download if you only want one and are not interested in the comparison.

These recordings are totally unrehearsed improvisations that took place at my home. As a consequence there is wandering and going down paths that were discarded. I attempted to curate the best parts of an all day session. Much of the music wouldn’t make sense without enduring the development before something jelled. Two pieces of this session were previously released and are included here to complete the session. Instruments – voice, trombone, udderbot, clarinet, 15 edo, 17 edo, 19 edo, 20 edo, 22edo guitars and fretless banjo, guitar and bass, gongs, Tibetan singing bowls, DIY erhu, 31 edo bouzuki, various electronics and percussion. We freely mixed tunings and our compositional goal was to have a good time! We hope you enjoy these recordings.

The One True Tuning

The Sorrow of Aleppo (solo 19 edo guitar, pseudo drop D tuning)

Friday, November 6th, 2015


The Sorrow of Aleppo is a 19 note per octave guitar solo that uses a “drop D” tuning modification. The scale in 19 edo is 0 3 5 8 11 13 17 19 or D E F G A B`b C^ D where ^ (up) and `(down) indicate 19’s version of “quarter tone” modifications. Works out to be a “D” melodic minor variant. Please excuse the wrong notes here and there.
