Here the characterizations are taken from [[http://en.wikipedia.org/wiki/Scala_%28program%29|Scala]], which also describes the scale itself as "Pelog Nawanada: Sunda". Chords such as 1/1 - 7/6 - 49/36 - 12/7 are therefore natural ones for 9EDO. The above scale generates the [[Just intonation subgroups|just intonation subgroup]] 2.27/25.7/3, which is closely related to 9EDO.

Like 16edo, 9edo can be notated two ways. The first is with sharp higher than flat, to preserve melodic contour:
D E * F G A B * C D
D - E - E#/Fb - F - G - A - B - B#/Cb - C - D
P1 - m2 - M2/m3 - M3 - P4 - P5 - m6 - M6/m7 - M7 - P8
The second way is with sharp lower than flat, to preserve interval arithmetic and chord names:
D E * F G A B * C D
D - E - Eb/F# - F - G - A - B - Bb/C# - C - D
P1 - M2 - m2/M3 - m3 - P4 - P5 - M6 - m6/M7 - m7 - P8


9EDO contains a pentatonic [[MOSScales|MOS scale]] -- 2L 3s (1 3 1 3 1) -- with a heptatonic extension -- 2L 5s (1 1 2 1 1 2 1, sometimes called "mavila" or "antidiatonic"). Indonesian pelog scales sometimes use five-tone subsets of a seven-tone superset in a similar way, and it has been suggested that Indonesian gamelan music stems from a [[http://www.neuroscience-of-music.se/pelog%20historical.htm|9EDO tradition]].
