This page introduces a proposed notation system for the [[2L 3s]] pentatonic scale.
This page introduces a proposed notation system centering the [[2L 3s]] pentatonic scale. This system is useful for tunings with very hard diatonic scales, making diatonic limmas and chromas counterintuitive.

The modes of the pentatonic scale has names in traditional Chinese music.
{{MOS mode degrees|Scale Signature=2L 3s}}
{{MOS modes|Scale Signature=2L 3s|Mode Names=Jué (角)$ Yǔ (羽)$ Shāng (商)$ Zhǐ (徵)$ Gōng (宫)}}

Standard diatonic CGDAE are used. F and B are omitted. The sharp and flat are represented as “qing (清)” and “bian (变/變)”, borrowed from traditional Chinese music theory. Normal sharp/flat can also be used when not leading to ambiguity.
