This is one of my second group of experiments in Integrated Frequency, developing key modulation. I took the Harmonic Progression material, from the Integrated Frequency 1 project, and utilized an extended form of the Overtone Series through other branching Overtone Series scales.

Modulating through all 12 chromatic keys, and utilizing rhythmic sounds derived from fundamental frequencies of R20 (root, 20Hz), the thematic harmonic progression material is stated three times in three different tempi, all inter-related.

Hope you enjoy!
