Broken Thoughts by Keeril Makan

Some Thoughts on Broken Thoughts:

Technology can extend the acoustic experience. The timbres, gestures, and the very space from which the sound emanates should originate in the acoustic instrument, in this case, the piano. All sounds are based on piano sounds. I was able to separate the percussive, hammer attack from the longer, resonant decay of the struck piano note. All sounds are created in real time in response to the gestures of the pianist. The MIDI piano in combination with both a sampler and a real time, software based, additive synthesis engine make this possible. All the computer-generated sound is localized by placing one speaker under the piano, blending together the sound of the piano and the synthesis.

Being unable to continue and develop a train of thought, musical ideas repeat and change, but ultimately their physicality is more compelling than their meaning. As the pianist's gestures become disassociated from the sounds they produce, the music becomes strangely emotive, as memory is in the foreground and the pianist's presence diminishes.

Broken Thoughts was realized at CNMAT (The Center for New Music and Audio Technology), with the assistance of Amar Chaudhary, through the support of a Garrett W. McEnerney Grant. Special thanks to Edmund Campion, David Wessel, Matt Wright and Richard Andrews.

20 Questions (1997 rev. 1999) by Jonathan Norton

What is a question?  How are questions formulated?  As the mind wrestles to grasp the concept of a subject, inevitably, questions begin to form . But not all questions are created equal.  Some may be ill-conceived and make no sense, resulting in more confusion.  Some well thought out questions, once asked, can be enlightening but raise yet further questions.  Some are really not questions at all, but simply a reiteration of the subject in the inquirer's own words in an attempt to understand. Sometimes frustration ensues, and the inquiry must be re-approached.  From thought to vocalization this piece explores the musical texture of a question.  This piece was realized through the use of granular synthesis, spectral reshaping and the re-sampling of vocal samples and computerized instruments.  All signal processing was done on a Apple PowerPC.

Incantation S4 by Matthew Burtner

Incantation S4 (1997) explores the integration of the saxophone and electronics as equal elements within a single, non narrative sound-space. Techniques of digital audio synthesis such as granular synthesis, spectral mutation, and spectral resonance influenced the compositional approach to the saxophone while the electronic part was inspired by a natural and organic conception of sound. "Incantation S4" is dedicated to Barry Truax and was composed during a residency at Simon Fraser University using the PODX system for quasi-synchronous granular synthesis. It was recently released on a solo CD of Burtner's music, "Portals of Distortion: Music for Saxophones, Computers, and Stones" from Innova Records (Innova 526).

Escuela by Christopher Burns

Escuela is the second in a series of piano pieces which somehow refer to places where I've lived - in this case, my first home in California, on Escuela Avenue. The piece is also bound up in my early experiences as a graduate student, thereby enriching the meaning of the title. In Escuela, a computer is employed to modify the sound of the piano during the performance. The performer controls this process from the piano keyboard, applying ring modulations which precisely reflect the pitch structure of the original piano music. The result is a kind of mirroring - the electronics describe the piano's music in the way that they alter its sound. Thanks to Juan Pampin for assistance with the software, and especially to Chris Jones, who provided invaluable advice on early drafts of the piece.

String X-ing by Tom Swafford

My goal in writing String X-ing was to combine my interests in composed and freely improvised music. I recorded myself playing short improvisations (the longest was about 2 minutes) and organized the material by category (pizzicato, glissando, lyrical melody, etc.). I used this palette of musical fragments to create the tape part. The live violin part (which is partly improvised itself) is made up of material derived from transcriptions of the original improvised fragments.  The name String X-ing is an abbreviation I used to label one of the categories of musical fragments. I also like the X because it conjures up the name Xenakis, whose use of extended technique for strings inspired me during the composition of this piece.

iICEsCcRrEeAaMm by Fernando Lopez-Lezcano

iICEsCcRrEeAaMm is now definitely in beta test. As in the software world, Marketing informs me that in future versions bugs will be squashed and new features will be added for the benefit of all listeners. "iscream" refers to the origin of most of the concrete sound materials used in the piece. Screams and various other utterances from all of Chris Chafe's kids were digitally recorded in all their chilling and quite upsetting beauty. They were latter digitally fed into the "grani" sample grinder, a granular synthesis instrument developed by the composer. "ICECREAM" refers to the reward the kids (and myself) got after the screaming studio session. The piece was composed in the digital domain using Bill Schottstaedt's Common Lisp Music. Many software instruments and quite a few other samples of real world sounds made their way into the bit stream.

Fracture for tenor saxophone and electronics (1995, rev. 1998) by Bruce Christian Bennett

Fracture, for tenor saxophone and four-channel signal processing, was commissioned by Michael F. Zbyszynski during the Fall of 1995. The signal processor used in this work is the ensoniq DP/4, controlled by a Macintosh computer running MAX software. I programmed MAX to change presets on the DP/4, to cross-fade between presets, and to control various parameters of the signal processing and the midi-mixer in real time. The performer uses a midi-foot switch to trigger the events stored in the computer. Most of the musical material of Fracture is derived from the opening measure; my intention was to fragment and elaborate the opening gesture over the course of the work in a way that was interactive with the electronics. The signal processing is carefully prepared to respond dynamically to the performer's playing. I was not interested in merely composing a piece for saxophone and electronic accompaniment; rather, I hoped to effectively allow the electronics to influence the musical material of the saxophone itself. For example, nearly two-thirds of the way into the piece, the saxophone line dissolves into noise and an exploration of harmonics; also, at various points throughout the piece the opening motif fragments and is offset by fractions of the beat in play with digital delays spatialized across all four channels. In this manner I hope to have more fully integrated the saxophone and its electronic complement into a more unified whole.
