The piece was generated using emacs-lisp and csound-x,
here's his description of the work:

"there are three kinds of chords in the piece, and they never overlap. The actual score I wrote calls three corresponding functions: 'simple-chord, 'chord, and 'slide-chord'

To compose the piece, I first wrote these functions roughly, then I called them with some parameters, tweaked the functions code so that I could get nice sounds, then I stopped modifying the functions and did the actual composition of the piece, this time playing with the duration and sequence of chords, and only tweaking the parameters sent to the functions.

When I got the final shape of the piece, I made some last slight tweaking of the functions internals (mostly to the way they handle volume and panning) in order to dynamise the more static aspects of the sounds."

Short Composition Competition

Tobiah has proposed an interesting project:

"I have an idea for a brief informal contest. Given a simple,
one-oscillator orchestra, provide a score which produces the
most beautiful piece.

I offer an orchestra that I crafted for the purpose
of this event. One can make use of very limited
envelope an pan controls. Obviously, the craft will
be in the score generation program (although one is
welcome to hand edit her entry!).

If there is interest, I suggest a seven day window
for this challenge. Only the scores should be
submitted at first. We can look at source code
later. For large scores, a URL might be best. I can host
scores if you send them to me in an archive format."

Here's Tobiah's orchestra for the competition. I propose
use this blog as a means of collecting responses.
