"A drone of varying densities built from layers of complex 
justly-intoned chords with scintillating harmonics."

I made this with Csound 5.0 RC2 (nice!).  It has something to do with La 
Monte Young's Opening, Magic and Magic Opening chords, but it doesn't 
use those chords literally.  No sine waves were harmed in the making of 
this music.

As always, comments are welcome.

Hey David, heard it already through cacophonous.org!  Nice!  Reminded me 
a bit of one of my pieces, Lamentation Siderales...

BTW, we have The Hype Machine tracking Cacophonous MP3 announces now...  
woo hoo!

Thanks, Jeff.

I need to go listen to that piece!  I have the MP3 here, and I 
definitely enjoyed Eroica Spettrale and Echoi from that set.  Thanks for 
the reminder.

Following up...

Jeff, that is a gorgeous piece, thanks again for reminding me to listen.

Well it never gets into those interesting use of beats as a percussion 
device but the beginning kinda...

The cool this is, I didn't plan for the beating effect; it was a natural 
consequence of the interval relationships.  But once I heard it, I got 
more deliberate about it.  I'll probably be doing more of that in the 
future.  I also used beating consciously in an earlier piece, The Gemini 
Nebula.

Hey, is there any way to map a rhythm to a dissonance ratio?  ;)  So one 
could plan your drone ratios around rhythmic concerns?  (Maybe this is 
obvious - but a technique might be nice).

Excellent question.  I don't have an answer, but it would be a good 
thing to know.  I'll be giving it some thought, though I'm not sure that 
my math is up to it.

The beat frequency is the difference between the two tone  
frequencies. For example, to get 120 bpm:

120 bpm * 1 minute/60 seconds = 2 Hz.

If the first note is 110 Hz, the second note should be

110 Hz + 2 Hz = 112 Hz.

There are some subtleties regarding positive and negative maxima, but  
the procedure should be useable.
