Bat Bomb – Harmonic Series

Friday, September 16th, 2016


Bat Bomb is part of an ongoing series of experiments to try to learn how to make aeolian harp type sounds. In this case I used Uhe’s Brazille with a patch that manipulated the overtone by adjusting the modwheel. Using my Linnstrument in MPE mode I was able to independently adjust the overtone (13 in total per note) by moving my finger in the “Y” dimension (which was routed to the modwheel channel control) and the root note from Carlos “Super JI” tuning by selecting the pad I played. The original patch had a lot of high end to it and are some time listening to it I decided to turn the filters down to try to get closer to a sine wave. Then I experimented with tempo. I find the 60 BPM version the most interesting at the time I am writing this post though there are some interesting peculiarities of each version. And, no, I don’t feel that came close to the aeolian harp, yet I think the experiment has its merit in learning sound design technique and audio result. Of course YMMV. I present the audio in the order I find most interesting. And yes, the bat bomb was real – click the photo to read about it as you listen.

Here is the audio spectrum analysis of the 60 BPM version. Click to enlarge.

Melodyne Deep Dive in an Aeolian Harp Sound Sample

Saturday, August 27th, 2016

The above aeolian harp sample (from 2014-11-07 21:12:51 pm) had an interesting sonority to my ears. I wanted to find out what the chord was so that I could reproduce it. So I put it into Melodyne to analyze the chord. As I listened to the file and looked at the display there seemed to be a bit of a disconnect. So I dissected the sample (Sections labeled A through H by ear – there are two disjunct groups) into individual files. Then I normalized them and ran them through Melodyne once more. The resulting sound files and analysis are below. You will notice that in some cases what was a single tone in the original now breaks into more than one note. In other cases more than one note is heard but Melodyne doesn’t show them as separate – I think in these cases the program analysis is tagging them as part of the harmonics which is shown below the main window of the program. Since an aeolian harp is a special case where the harmonics of this is a special case, interesting though it may be. Most of the dead air was removed from the A through H audio samples.

The labeled file below is in Hz. You can download the audio and graphics here as a zip file.

Spectrographic Cornfields Recursively

Monday, July 18th, 2016


standing in the cornfield you watch the corn grow and
the searing hot days pass on to night to day to night to day,
taller and taller, until you are one with all there is…
for you are one of them…
your roots dig soil,
your stalk stretches greedily for every ray of the murdering sun
in the anguish of a midsummer’s thirst…


Perseus Cluster (processed electric aeolian harp)

Thursday, July 7th, 2016


Perseus Cluster (processed electric aeolian harp) is an ambient directed aleatoric piece – the wind played the aeolian harp after I tuned it. I recorded the result and then I processed the harp through a battery of effects to create an ambient piece that consists of a drone of processed harmonics.

Not for the faint of ear!!
Rock Trio in Harmonic Series is an extreme recomposition of the Nevadatite material put into the context of rather heavy and dissonant rock trio of guitar, bass and drums using the raw unreduced harmonic series and the idiosyncrasies of Kontakt.

Poly Tuned Synth Collection uses the following:

Z3ta+ 2 Denny Genovese 24 – 28 harmonics w/ ribbon controller
absynth’s harmonic series w/ TC Data
aalto’s harmonic series w/ TC Data
albino 22 edo w/ TC Data
Xen FMTS 2 harmonics 12-24 w/ Linnstrument

This is mostly about being a study to learn using midi over wifi with toby bears rtpMIDI and TC-DATA

Fantasia for Harmonic Series Tuned Piano uses Soniccouture’s Hammersmith Virtual Piano Pro (thanks to very generous coupon). The piano is tuned with Kontakt built in overtone script. As for the musical form “Fantasia” it is used here in the tradition of being an improvisation.

Hommage Pour Paul H. Muller

Tuesday, August 4th, 2015

This is an ambient music video in tribute to my 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.
