Set Theory – Parallel Interval

This is probably the most common harmonic mixing transition – corresponding to one counter-clockwise rotation on the circle of fifths. In this case, the first track is in Bb minor phrygian, and the second track is Eb minor phrygian. So the root key has shifted up by 5 semitones. I call this a parallel interval because, due to the modes being the same, all notes are transposed an equal amount. Most harmonic mixing tools don’t actually differentiate between the different minor/major modes (instead only detecting major or minor and the root), so a parallel interval is a bit more specific. The transition starts at 6:10.

Set Theory – Complement

There’s a concept in musical set theory called complement, where the set of notes is given as the set of all notes which are not included in the original set. Applied to a musical mode, there may be multiple complements. In this case, I’ve chosen the complement whose root is a tritonic interval (6 semitones) from the original note. Specifically, the mode of the first track is A minor dorian and the mode of the second track is Eb Major Mixolydian.

This transition begins at 4:36, pivots at 5:34, and completes at 6:04. Try to pay attention to the notes involved, most prominent being the tritonal interval between roots. I’ll be uploading more examples of various mode transitions, cause it’s neat IMO.
