Inspired by the
composition techniques in electroacoustic music, such as additive synthesis and
spectrum analysis, the piece Partials is a realization of those techniques in a multi-channel sound context.
The 8 speakers serve as 8
sine wave generators that produce sine wave tones in specific frequency
relationship. When the frequencies are played together, a complex tone rather
than separate tones is perceivable by listeners, as a result of additive
synthesis. Meanwhile, controlling the dynamics of each speaker is like
controlling each partial of the complex tone, which is not only affecting the
volume of it but its timbre as well. In a multi-channel setting, any subtle
manipulation of partials is being articulated and exaggerated, making the
change in timbre more perceivable. I hope the slow modulation of timbre in Partials would have a sculptural
property that could be experienced over a fixed time duration.
