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.

The [[ennealimmal]] temperament, which contains 9et as a subset and are excellent in the 7-limit, maps the scale above consistently with regards to their respective steps. Thus 9edo can be viewed as the trivial tuning of ennealimmal.
