This page documents VectorGraphics' personal system of interval regions.

== 1. The thirds ==
The thirds (intervals ranging from approximately 245.7 to 456.3 cents) are labelled similarly to how the corresponding [[Mediant (interval measure)|mediants]] are assuming a just 3/2 fifth, but with an additional distinction in terms of neutral thirds. Thus, the range of thirds appears as follows:
{| class="wikitable"

| rowspan="3" |Supermajor third
|Neogothic major third
|-
|426 - 441
|Supermajor third
|-
|441 - 456
|Ultramajor third
|}
Octave complement names are derived naturally from these; i.e. "pythagorean major third" -> "pythagorean minor sixth".

However, when labelling thirds in particular, it is best to speak in terms of mediants.

== 2. The seconds ==
Intervals smaller than 246c also have names as seconds. Some of the names for sevenths are somewhat irregular, so they have been supplied where necessary.
