disquiet0350-NightPatterns by dascott

I created this track on my laptop while vacationing in Vancouver, B.C. Rather than go out searching for audio material, I decided to keep it simple and just use sine tones.
The structure is simple as well: A seven-note pattern, C-D-C-F-E-F-D is played once over the 3-minute length of the piece. Layered over that is the same pattern played twice as fast, repeated once. Over that, the same, twice as fast, repeated twice, and so on for four or five layers. The faster the pattern, the lower the octave, though layers do share octaves.
The "instrument" playing all the tones generates a sine wave with added even harmonics (2nd, 4th, 6th), with a slow envelope for both volume and for the slow vibrato. The volume is also modulated by the LFO, so the tones shimmer.
Because (you might have noticed) the repeat count does not compensate for the halving of the length each time, the faster layers finish first, gradually leaving just the slowest at the end.
