Bowed gongs and a piano tuned to a Golden ratio derived tuning (see below) and driven by Melodyne’s polyphonic interpretation of the gong track.
1/4 comma meantone tuned piano driven by the same gong derived score.
This is an ambient music video in tribute to my Sound-in.org colleague Paul who has been experimenting with constrained aleatoric compositional techniques. This is the sound of my electric aeolian harp combined with time lapse video. The harp is a constrained aleatoric device because I tune the string but the wind plays the strings which generates harmonics of the strings.
A montage created from a trip to the Museum of Science and Industry in Chicago. All of the audio in this video comes from the visit processed to some degree. The “music” is tuned to Just Intonation by Melodyne. This wide-screen video is best enjoyed full screen since there is significant detail.
The video is of the base 22″ Wuhan gong hit after 35x Paulstretch with the noise reduction on. What remains are the isolated gong tones buried in the crash and the drawn out “hum” tones. Caution – there are some very loud, high pitches. Best viewed at the highest resolution you can manage.
The above is the audio spectrum of the noised reduced and 35x stretched track using a FFT transform. Click the picture to enlarge it.

With the gong tones in Melodyne I was able to retune them to 22 edo porcupine with magic 7th variant (below) – for my taste I used Melodyne to remove the highest “hum” note which I disliked.

For Chamber Ensemble, Grain Silo, and Wrecking Ball in 1/4 comma meantone is a semi-aleatoric recomposition of midi extracted from a multitrack analog synthesizer piece called “Iron Harvest“.
Using Melodyne Single Track I extracted the midi from each analog synthesizer track. This was rather interesting in itself since non-traditional pitched elements of that performance were interpreted as pitched material. So, for example, a change in filter resonance created an additional pitch. This rich input material was then edited and used as a score for the the ensemble.
The ensemble consists of solo strings (violin, viola, cello, and double bass), solo alto flute, bass trombone, contra-bassoon, bass clarinet and harp (with arpeggio applied) from the Garritan Personal Orchestra sound set with the included 1/4 meantone tuning (below). The video was shot with a Fujifilm exr F660 while on a trip to a different destination, in other words, “a happy accident”.
The sound of the wrecking ball and the collapsing grain silo are used as found sound percussive elements in this piece. The video sound track was cleaned by noise reduction and application of a noise gate to keep most of the sound of the strikes and falls minus the background traffic noise.

a gentle wind across the plains of Pluto is processed aeolian harp. I put new guitar strings on my harp which made it much more sensitive.
These are demonstration pieces of a technique
– not intentional pieces of music…
The title should really be SIGNAL looped analog synthesizer.
The basic idea is to use the Korg mini MS-20 as a sound source and use a delay in the signal path to return the delayed signal to the Korg’s frequency to control voltage converter. This is then sent to another delay / reverb to attempt to smooth some of the sharp changes. Invention 2 is the more musical of the two inventions and relies on sound on sound to fill out the signal. Invention 1 is using a long delay time. The graphic, crude as it is, contains the actual signal path. The motive is to find some other way than a sequencer or LFO to generate a self-performing analog system.
Snow and Wind – the electric aeolian harp played by snow flakes impacting the strings and of course wind during a light snow.
