Linnstrument Improvisation in 106 edo (video)

January 16th, 2017



(best viewed full screen, video is 1080p)

Linnstrument Improvisation in 106 edo (audio only) is a moderate length piece that explores the wonderful soundscape that 106 edo can create. In a previous post I received this comment on Reddit’s microtonal subreddit “I generally like the sound of Bohlen-Pierce. I’m interested in this piece but confused by your methodology.” So I thought I would write something about my improvisation method as the video compiles. Essentially my approach to improvisations is an aurally informed pattern recognition with development. If you watch the video closely you will see places where I run into a note combination I don’t like and back away from it somewhat quickly and in others where I find a fingering I like and replicate it in either hand or as “blocks” played off against each other. 106 notes per octave makes melodic development especially challenging though it is rich harmonically with many nuances and to my ears a way of letting you settle into a harmony that may at first sound strange but re-orientates your ears to hear it as pleasing or at least interesting. Certainly with 106 edo it is very hard to get caught up in 12 edo sounding cliches! So I hope that gives a little bit of an answer to the question I received on Reddit. video download

Recomposition Using Celemony’s Melodyne Editor

January 15th, 2017


Best viewed at the highest resolution available. The native video is in 1080p

By using Celemony’s Melodyne Editor I rearrange the notes within a droning sample from my DIY electric aeolian harp. The tuning is nominally Bohlen-Pierce (stock with Melodyne) but the nature of the aeolian harp means additional pitches are present.

Loquebantur variis linguis in Adaptive JI normal and half speed

January 11th, 2017

The video is best viewed full screen. The half-speed version starts after a “note for nothing” to capture the reverb tail and a few seconds. The passing tones are very evident and dissonant in the half speed version. Loquebantur_variis_linguis PDF

The Tempest Prognosticator

December 31st, 2016



In 24 edo (largely) using Shoom, Gestrument, and Bowls HD => download

The tempest prognosticator comprises twelve pint bottles in a circle around and beneath a large bell. Atop the glasses are small metal tubes which contain a piece of whalebone and a wire connecting them to small hammers positioned to strike the bell. In his essay Merryweather described the workings of the device:
“ After having arranged this mouse trap contrivance, into each bottle was poured rain water, to the height of an inch and a half; and a leech placed in every bottle, which was to be its future residence; and when influenced by the electromagnetic state of the atmosphere a number of leeches ascended into the tubes; in doing which they dislodged the whalebone and caused the bell to ring. ”
— George Merryweather

The leech would have difficulty entering the metal tubes but would endeavour to do so if sufficiently motivated by the likelihood of bad weather. By ringing the bell it would signify that that individual leech is indicating that a storm is approaching. Merryweather referred to the leeches as his “jury of philosophical councilors” and that the more of them that rang the bell the more likely that a storm would occur.

In his essay Merryweather also noted other features of the design, including the fact that the leeches were placed in glass bottles placed in a circle to prevent them from feeling “the affliction of solitary confinement”
