Attn. Sonic Foundry,
Hey, I wanted to pass the following interview along with
you, in which Sonic Foundry products are highlighted. It's
from the current Music and Chaos Theory feature at
http://www.live365.com .


Math, Music and Chaos Theory

Thomas Park's music is not from a Star Trek Voyageur
episode, but it could be. He's created music by mapping the
complex patterns of nature to music by way of complex
fractal mathematics and some tricked-out studio gear.

Listen: http://www.live365.com
Our Skies Radio (56K Modem)
Could be part of Brian Eno's Ambient series.

PanMuse Global Radio (T1/DSL)
Could be John Zorn's evil twin.

Park says he "composes" his music on the following gear:


Algorithmic Arts Soft-Step Pro MIDI Sequencer
Sonic Foundry Acid Rock 2.0 software and various loop
libraries
Cool Edit, shareware version
Wingroove Midi to .wav conversion software
Anvil MIDI studio (shareware)
E-machine 400id PC
We talked to Thomas Park about his methods, the math, and
the music that results.

Live365.com: Your profile reads, PanMuse Global Radio ...
focuses on music created using data derived from simple
mathematical ratios and natural phenomenae. How, exactly,
does this work?

Thomas Park: I look for sequences of numbers derived by man
from nature or mathematics. Then, I try to apply these
sequences to music-- usually, as directly as possible. My
theory is that nature, math, and music have much in common,
and we need merely to shed a light on these congruences and
they will surprise us.

Live365.com: It's an incredible concept! Can you elaborate
exactly how you go about creating these compositions, from
start to finish?

Thomas Park: I have 2 main methods.


Research (usually online).
Find a sequence of numbers referring to some natural or
mathematical phenomenon.
Try to find sequences that are actually series (referring
to elements that move from simple to complex, small to
large, East to West, etc).
Input direct "snapshots" of these sequences into
Mixing/Sequencing software (esp. Sonic Foundry 2.0)--
where, for example, the number "2" generates a note 2 up
from the base of the selected scale.
Try to build compatible sounds using, as much as possible,
different views or snapshots of the same sequence.


Find a sequence of numbers referring to some natural or
mathematical phenomenon.
Try to find sequences that are actually series (referring
to elements that move from simple to complex, small to
large, East to West, etc.)
Input the numbers into "seed" switches in Algorithmic Arts
SoftStep Pro software.
Use a variety of fractal-generation and number-generation
modules, together with quantization, to produce a sequence
of pitches and duration's using the source data for seeds
in as many cases as possible.
"Mix down" the resulting MIDI file using Anvil Studio
software, further quantizing, selecting instruments, and
greatly reducing tempo.
I tend to use the first method for "PanMuse Global Radio"
pieces, and the second method for "Our Skies Radio" pieces.

Live365.com: Do you assign certain
sounds/frequencies/tones/timbres to certain intervals or
mathematical functions?

Thomas Park: The sounds are chosen at my discretion. The
frequencies vary in scale but, in general, match the source
data in degree.

Live365.com: How much of this music is generated via the
equations you're feeding it, and how much is your creative
input? Is "equations" even the right word here?

Thomas Park: "Equations" is fine! I try to find sequences
of data that seem to illustrate one "equation" or another--
logarithmic, arithmetic, etc. . . and I stick with the
source data when composing as much as I possible can.

Live365.com: What kinds of natural phenomena do you compose
from, and how do you extract the mathematical information
from them?

Thomas Park: I have used, for example, white Dwarf star
data, a group of dinosaurs, various stars, and, recently,
data derived from the movements of a sea turtle (tracked by
Berkeley scientists) for nature-inspired pieces. I look for
a sequence of numbers, in which some progression forms the
independent variable-- time, size, distance, etc. These
sequences then are made to correspond to temporal
(independent) and pitch (dependent) variables when
composing.

Live365.com: How did you get hooked up with the data from
the AAVSO observatory?

Thomas Park: The AAVSO supplies free data in the "Quick
Look" section of its website, at: http://www.aavso.org/ql/.
Mr. Price of the AAVSO, having been informed of the Our
Skies Radio concept, approved of the use of AAVSO data,
within certain financial constraints.

Live365.com: Okay, here's where my geeky side comes out. I
am no mathematician, but I'm fascinated by the ways music
maps to math. How would you describe the relationship
between music and mathematics?

Thomas Park: Lately, I have been wondering-- aren't numbers
much like symbols, that, in part, make our minds
comfortable, in the same way that notes on a scale make our
ears comfortable (hopefully). Numbers are like notes, just
more generalized. In a strange way, if I can apply a number
to quantify a motion or phenomenon, and I can apply a
number to quantify a musical note, then the number becomes
a symbol of both the phenomenon and the note. This gets
interesting when sequences and series are applied, as
supplied by a non-musical source, and applied to music.


Here ends the interview. Please feel free to print any or
all of this material if you are
interested in passing along some more useful qualities of
Sonic Foundry products.
