The base intervals come from the circle of fifths from -7 to 7 fifths: diminished octave, diminished fifth, minor second, minor sixth, minor third, minor seventh, fourth, unison, fifth, major second, major sixth, major third, major seventh, augmented fourth and augmented unison. This is unlike Igliashon's [[Extra-Diatonic Intervals]], which only uses -5 to +5 fifths. The reasoning for the expanded range is that a chromatic scale is made of 6 augmented fourths and 6 diminished fifths, as well as 7 minor seconds and 5 augmented unisons. In the other hand, the diminished fourth at -8 fifths is considered a wolf major third in [[5-limit]], and a septimal major third in [[7-limit]], so this system names it a high major third instead.

Unison–second refers to the interval in the middle of augmented unison and minor second (like the ambiguous 100 cent interval in [[12edo]]), not in the middle of unison and minor second.
