Speaker Synth is an interesting synth DIY project – a five-speaker array with no external audio input, created by Lesley Flanigan. The only components in the system are the instrument’s speakers, piezoelectric microphones, amplifying circuits, and the hands of the performer.
Speaker Synth is played by positioning individual piezo microphones with their corresponding speakers and manipulating their associated on/off and volume controls to induce a variation of feedback effects. During the performance, samples from both Speaker Synth and a vocalist are captured and sequenced to build a dense sonic pallet of rhythms and melodies.
The performance explores music making through structuring noise, highlighting relationships between analog and digital sound synthesis and between human voice and the voice of an instrument.
