Interval modifiers in various systems

User:PiotrGrochowski/Extra-Diatonic Intervals — 43edo — this is based on 43edo. Unlike many other size based naming systems, it has an augmented unison and diminished octave. It uses second–third, third–fourth, fifth–sixth and sixth–seventh as 43edo splits the minor second (between major second and minor third, major third and the fourth, etc.) in half.

It uses high and low modifiers.

• Neutral intervals (neutral second, third, sixth and seventh) are split in two. These are labeled high and low.
• Highs and lows as a modifier is used on many intervals, and raises or lowers an interval by one 43edo step. One step in 43edo is a meantone diesis, which has similar septimal functions as super and sub in some systems.

User:PiotrGrochowski/Extra-Diatonic Intervals — 50edo — this is based on 50edo. Unlike many other size based naming systems, it has an augmented unison and diminished octave. It uses unison—second, fourth—fifth and seventh—octave as 50edo splits the major second (between major second and major third, minor third and the fourth, etc.) in half.

It uses high and low modifiers and super and sub modifiers.

• Neutral intervals (neutral second, third, sixth and seventh) are split in two. These are labeled high and low.
• Highs and lows as a modifier is used on many intervals, and raises or lowers an interval by one 50edo step. One step in 50edo is a meantone kleisma.
• Supers and subs as a modifier is used on many intervals, and raises or lowers an interval by two 50edo steps. Two steps in 50edo is a meantone diesis, which has similar septimal functions as super and sub in some systems.
