Dear Jx; The harmony is based on a cluster of chords that is diatonic to one scale, say, C major or C minor. These are the "primary" scales. We know the major. Also the C minor chords can come from the C natural minor or C harmonic minor scale. The secondary scales, on the other hand, cause tension that needs to be released to the listener: diminished, wholetone, melodic minor scales do not sound good by themselves for too long such as an unresolved situation. The cycle of fourths can go without secondary scales as C major to F major to Bb major, etc. But try it backwards for an instant, oooh, try this: C major to F major back to C major. That F major to C major will not sound good unless you stick in a secondary scale, the B diminished scale can lead to C major, stick it in there. This way we can move the tonal center around if we are in the key of C major for more interest. I like scales, Ken
