only three musical notes were used in the creation of this drone piece
C, G and Bb
so, yeah... a power chord for the most part with a flattened seventh thrown in here and there to "spice it up a bit"
as simple as this piece is I did actually "perform" it, though not in the traditional sense, other than the occasional high pitch pad that comes in to add that flattened seventh
instead, I twiddled knobs, like you do with modular sometimes, changing the depths of CV inputs of some of the filters into which I fed many low frequency oscillators, hence the name of the piece
