Note: These
works were composed by use of original algorithms
the Capsule
speech-based algorithmic composition
(2011)
Program Note:
The Capsule is an
electroacoustic dance piece in which every sound heard was
created by manipulating speeches from prerecorded interviews.
Choreographer Vickie Nidweski recorded interviews with recent
university graduates asking them about their degree of
preparedness as they entered the next stage of life. Their
recorded responses were processed in novel ways to make this
piece; no other sounds were added.
Lapp Cables
real-time algorithmic composition
system made from Lapp Group industrial cables
(2011)
Program Note: The Lapp
interactive music system composes music in real-time using data derived from
Lapp Group cables. Using custom software, data from the cables were mapped
to scales, chords, and rhythmic patterns to algorithmically generate the
music. The same cables were then made into an instrument capable of
performing the generated music.
As the cable controls are manipulated, aspects of the music, such as the
chords, tempo, key, instruments, and more, will change. The amount of volume
of each instrument in the ensemble is mapped to one of the lights above each
cable which reflect changes in volume.
In real-time, users then control different aspects of the piece, synthesized
in a jazz style at the client's request.
The piece and system were commissioned by
Lapp
Group USA for the company's
anniversary function. In addition to guests performing with the system, an
artist improvised a painting while the system performed.

Program Note:
This system is designed to take real-time user input through a
microphone and process it in novel ways. The user needs only to
open the program and begin speaking. The spoken voice is
recorded and analyzed using an FFT, and the spectral data is converted into a 3D
matrix using a technique by my former teacher,
Luke
Dubois. This software is based heavily
on his model. The 3D matrix is then scanned to resynthesize the
original spoken sample. The novelty of resynthesizing from an
image is that visual effects can be applied which change its
sonic properties. Over time, the original sample will change
substantially--there are no other sound sources or effects
introduced in this system: everything heard is derived from the
original sample. In this piece, the user says "God"
one time. It is
then processed according to a deterministic processing score that the software follows;
nothing is random.

Description:
the following compositions were made using original algorithms.
The algorithms used "rule-based" approaches such as the rules
that commonly dictate voiceleading, harmonic direction, and
form. Other compositions employed "data driven" techniques that,
instead of being "rule-based", attempted to generate new music
in a style based on a larger sample of extant musical data.
Compositions were created using
original software written in LISP and/or Max/MSP from 2006 - 2008. For more

in the player.
