This page introduces a proposed notation system centering the 5L 7s chromatic scale. For the meantone chromatic scale 7L 5s, there are two approches to use this system, just like using the standard notation system for the antidiatonic scale.
Intervals
The names according to quasi-diatonic MOS notation are not intuitional, so different names are given here. “Sem” stands for “semitone”.

Note names
Latin letters ABCDEFG and Greek letters αβγδε are used. Latin letters represent the same notes as diatonic. Each Greek letter represents the note a chroma below the note marked with the corresponding Latin letter. Ups and downs are used for altering Pythagorean commas.
| Chromatic | Diatonic |
|---|---|
| D | D |
| ε | E♭ |
| ↑ε | D♯ |
| E | E |
| F | F |
| γ | G♭ |
| ↑γ | F♯ |
| G | G |
| α | A♭ |
| ↑α | G♯ |
| A | A |
| β | B♭ |
| ↑β | A♯ |
| B | B |
| C | C |
| δ | D♭ |
| ↑δ | C♯ |
| D | D |
Staves
A 7-lined or 9-lined staff is prefered. To improve legibility, the lines can alter between thin and thick ones. The note C, E and α should be on thick lines.
