JI clock (was Re: [MMM] Re: Rhythm)

🔗Aaron Krister Johnson <aaron@...>

Funny that this discussion is going down...I did a piece on Jan 30th 2010 on
the first "dark concert" as an opener which was a Csound representation of
the overtone series played as pulses, up and down from 1 to 24 and back,
adding the pitches which were whole multiple of 48HZ, then taking them away.

http://www.akjmusic.com/audio/ji_clock.mp3

I only found out later that this was the idea behind the Henry Cowell's
"Rhythmicon"...IOW, I had independently hit on the same idea for this simple
process piece as Cowell did!!!

I used an almost sawtooth wave towrds the bottom and made the higher pitches
have progressively more triangle-wave timbre to keep it from being
overbearingly piercing.

What I enjoy here is the Moire-like patterns that emerge from the complex
interaction of all the simultaneous layers of rhythm. Let me know what you
think.

Hopefully, I'll post my latest kalimba adventures tomorrow...I wrote a
23-edo anti-diatonic piece in 17/8 meter for alto kalimba, but I've been too
busy to polish the recorded take to my liking...I'll see if I think tomorrow
will bring me a halfway decent take that I'm okay to share...I want to
really nail the dynamics and layering and rhythimic tightness as much as
possible...it's a difficult instrument to really play well, more than one
might think at first glance...

Thanks, but I really think you should just thank mother nature, b/c this is

Okay, maybe I get a little credit for making a decent sounding

Really nice. The interesting thing is that your adding different
overtones here and putting them at tempi proportional to their
frequency mimics what actually happens to the waveform of a sinusoid
as you add harmonics to it. You could probably make a cryptography
algorithm based on this idea. Good work.

That's a cool track, Aaron!

Here's something that uses a similar idea (and I was definitely thinking
of Cowell when I made it), made with sine waves and binaural beats. The
drones in the justly-intoned chord create binaural beating patterns
where the beating rate of each voice is proportional to the voice's
pitch ratio.
