Diatonic Harmony is the result of the imposition of the Window (from MELODY) on Free Harmony.
As its name implies, it is diatonic but still arhythmical (without discrimination of beats and off-beats).
Having no place to "breathe" prevents it from being truly tonal.
Its chords (being inside the Window) are of varied shape and strength.
This is the Harmony used for many of the examples of Transformations
because they can be advantageously demonstrated in this form of Harmony
(that of the Natural Canons).
