== Theory == | |||
=== Primodality === | |||
Through the lens of [[primodality]] theory, the moon dust scale is an over-7 scale. | |||
It occurs above the [[tonic]] in [[112afdo|the 112th mode of the harmonic series (112afdo)]]. (''See: [[overtone scale]] and [[harmonic series]]''.) | |||
=== Enumerated chord === | |||
Written as a JI chord, the moon dust scale is: | |||
* <small>56:68:76:84:126:133:154:196:224:252:308:336:504:532:616:784:896</small> | |||
