Program notes

Two-Tone Bell Fish by Amar Chaudhary

Two-tone Bell Fish unfolds as a back-and-forth between a melodic flute solo and an electronic exploration of the instrument's noisier side, in which the acoustic sounds of the flute become the source for a real-time electronic accompaniment.   In addition to those mainstays of electronic music, amplitude modulation and delays, the technique of resonance modeling is used to produce metallic percussion effects, including the "Two-tone Bell" that gives this work its name. There are also scattered samples based on flute recordings, as well as another "flute" you might recognize from your record collection. I would like to thank Adrian Freed and Matthew Wright for their help with the many technical challenges involved in this performance.

Still, Yet, Again by Linda Antas

Still, Yet, Again was realized at the Center for Advanced Research Technology in the Arts and Humanities and the School of Music Computer Center. The piece was created with Csound and Common Music on a Silicon Graphics computer. In addition to purely synthetic sounds, sampled sounds of struck PVC pipe, piano, propeller-driven bomber airplane, cymbal, canon fire, and a short orchestral chord are used, processed using techniques including phase vocoding, linear predictive coding, filtering, and the sndwarp unit generator. The final mix was done with RT.

Snakebyte for Electronic Wind Instrument (1994, rev. 1999) by Bruce Christian Bennett

Accursed be you
of all animals wild and tame!
On your belly you will go
and on the dust you will feed
as long as you live.
I shall put enmity between you and the woman,
and between your offspring and hers;
it will bruise your head
and you will strike its heel.

Snakebyte is composed for electronic wind instrument and frequency modulation (FM) synthesis. The piece begins with a harmonic timbre (associated with fast, quiet music of a limited intervalic scope) and ends with an inharmonic timbre (associated with slow, loud music with a seven octave tessitura). The gradual transformation from one timbre to the other is effected by continuous, real-time control of an equal power cross-fade between the amplitudes of the modulators in an FM algorithm based on a single carrier model: one group of modulators with whole number frequency ratios to the carrier, and the other group of modulators in a 1.41:1 ratio to the carrier. Some very interesting timbral variations occur at various points between these two extreme states. A sample of a shakuhachi flute is used to reinforce the FM synthesis.

On the Presence of Water by Bret Battey

On the Presence of Water is a sound and image meditation on water as a spiritual and psychological archetype. Computer manipulations of found sound and imagery knit tightly together to express a narrative of the subconscious. The video and computer music were developed in parallel, with creative insights in each medium influencing work in the other. The music was created in the University of Washington School of Music Computing Center. Primary tools were Csound, Common Music, and RT on SGI computers, with Csound extensions by Richard Karpen. The video was created in the U.W. Center for Advanced Research Technologies in the Arts and Humanities (CARTAH), primarily with Adobe Premiere. "On the Presence of Water" was recognized with an Honorable Mention in the 1998 Prix Ars Electronica (Austria).

Never time for Not by Linda Antas

Although flute is my instrument and I started composing before I took up the flute, Nevertime for Not is my first work for solo flute and the first work I've written specifically for myself to play. I was pleasantly surprised by the process that resulted in the composition of the piece, although I plan to make some changes in the piece itself. The electronic techniques are similar to those in Still, Yet, Again, while the flute writing explores the compositional uses of a wide variety of flute sonorities.

Sounds from the Broom Closet by Michael Zbyszynski

Sounds from the Broom Closet was originally composed to accompany dance, and was commissioned by the choreographer, Ondrea Aackerman. The live performance included speaking and sweeping of brooms. These sounds became the source material for the outer sections of the work. I tried to create a continuum from sweeping to speaking, using whispers and "talking brooms". The middle sections are more abstract. The second is a small homage to Jean-Claude Risset. The third section seems simple enough, but actually features an analyzed and resynthesized digeredoo (and the residual between the resynthesis and the original) that took more time to create than anything other single element in the piece.

Pater Noster's Tricyclic Companion by Bret Battey

Flautist Sarah Bassingthwaighte commissioned Pater Noster's Tricyclic Companion in 1998. Inspired by her energetic personality and command over fast passage-work, I wrote a virtuosic display piece emphasizing driving, syncopated rhythms and a dense, layered accompaniment.

I composed the work in a traditional "piano score" -- albeit not a humanly playable one -- and then "orchestrated" it for a mixture of MIDI synthesizer, computer-controlled acoustic piano, and Csound sound sources. The challenge I set for myself was to render this highly note-oriented accompaniment convincingly with electronic means -- despite the fact that this is precisely the kind of thing that computers and synthesizers seem ill suited to achieve. After discarding numerous orchestrational strategies which were too obviously "electronic" to my ear, my chosen solution was to treat the acoustic piano as the primary sound source, with electronic elements coloring and highlighting the sound.

The title does not mean anything in particular. For me, the phrase evokes something just short of the strangely unfamiliar -- matching the essential character I was seeking to establish in the piece itself.

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 foregrounded 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.
