Our first oscillator circuit of the project was an exploration into polyphony, we used a Hex Schmitt IC Chip to mix down two tones into one output. One tone was determined by an LDR and the second tone was determined by a potentiometre. We experimented with swapping in and out a range of capacitors to alter the tones. We were interested in the listener experiencing and affecting the subtle disonant and sometimes resolving spaces between two tones. One of our ideas for a lioght source (and potential installation idea) is to bath a room in coloured light and listen to the light theremins play thesound of the a changing colour spectrum. Today we tested this out in a lofi manner by playing a spectrum video from a mobile phone directly onto thr LDR, the sound change was slow and disctinct with each colour.
