variations

this set of pieces applies the classical idea of variation to spatialization techniques. sounds - sonorities, motifs, phrases - are transformed through placement in a variety of sonorous spaces, which act somewhat like filters, emphasizing specific perceptual aspects. in contrast to the classical method there are no clearly stated "themes", but rather a continual process of spatial redistribution.

two exemplars that informed my compositional process were webern's variations op. 27 and the late, short prose works of beckett such as ping; the webern for its clarity of construction, its specific technique of variation and its referencing of past procedures to achieve new results; the beckett for the "aha" moment it inspired when its underlying structure became evident, revealing its radical take on point-of-view, a perceptual shift like re-interpreting a reversible figure.

"variations" began as performances on the "portable multi-channel sound system", a complete 12 channel system that fits in a suitcase, with which i've been gigging for the past couple of years. performances on this system involve interacting with algorithmic processes that engender the basic structural aspects of the music including not only pitch, rhythm and timbre but also spatial parameters, which determine distribution among the 12 speakers, as well as eq settings, delay and reverb mix. recordings of a number of performances were edited and manipulated and ultimately reduced to 8 channels.

from the start, it was my intention to explore the possibilities of recreating the sense of immersion one experiences in multi-channel listening within a stereo field. therefore, the stereo versions of variations aren't intended as reference tracks or substitutes for the "real thing", but as fully realized statements in their own right, with perhaps a shift in emphasis from spatial characteristics to the act of filtering.

the set, 12 pieces in all, is available in three formats: stereo uncompressed files for download; stereo mp3s for streaming; 8 channel .wav files for playback, via the daw of ones choice, on an 8 channel sound system. additionally, contour editions is offering a complete system for 8 channel playback which includes the files on ssd card, a "waveplayer" device, amplifier and 8 custom speakers made with high quality drivers and improvised resonators. an example of this complete system is shown in the linked photos.
