Expanding on my work with Speaker Synth, I plan to orchestrate a choir of feedback loops using a similar piezos/speaker circuit.
The sounds of electricity from a basic analog circuit being cycled through a feedback loop are rich with nuance. From one speaker, many sounds can be shaped: feedback.mov
I began to list different sound characteristics that certain speakers leaned towards, including their natural frequency range, rhythmic and melodic tendencies, and their unique quirks. Essentially, this list is a character analysis, pin pointing personalities or "voices."
Unlike Speaker Synth, I plan to build each speaker into its own independent structure. The resulting Speaker Choir will be an arrangement these voices like a choir in both physical and sonic orientation, and explore the effects of their interplay.
Technically, I will build circuit for each speaker/piezo to allow for an optional, external input and output, although I plan the first performance to remain as simple as possible and not utilize these modifications. I will also incorporate an optional digital power switch for future switch control.
