This experiment, using Integrated Frequency, is an exploration into harmonic progressions both within the overtone series itself, as well as modulation to other overtone series following the circle of fifths derived from the original series of R20 (root 20 Hz). (More to come on this process in Integrated Frequency II ).

In this short piece, six overtone series are used, along with their corresponding tempos. The tempos are also in relationship to one another ‘by fifths’ if you will, following the same sequence. Within each key, harmonies are derived in their own progression. Think of it as a harmonic progression inside another harmonic progression.

The point to this experiment is to show the subtle intonation differences between the keys as they modulate from one to another. Everything is inter-related to R20, which creates cohesiveness, even though there are multiple microtonal shifts.

Hope you enjoy!
