| '''7L 2s''', '''mavila superdiatonic''' or '''superdiatonic''' refers to the structure of octave-equivalent [[MOS]] scales with generators ranging from 4\7 (four degrees of [[7edo]] = 685.71¢) to 5\9 (five degrees of [[9edo]] = 666.67¢). In the case of 9edo, L and s are the same size; in the case of 7edo, s becomes so small it disappears (and all that remains are the seven equal L's).
| | == Note names== |
| | | 7L 2s, when viewed under Armodue theory, can be notated using Armodue notation. |
| From a regular temperament perspective (i.e. approximating [[low JI]] intervals), this MOS pattern is essentially synonymous to [[mavila]]. If you're looking for highly accurate scales (that is, ones that approximate low JI closely), there are much better scale patterns to look at. However, if 678 cents is an acceptable 3/2 to you, then [[Pelogic_family|mavila]] is an important [[harmonic entropy]] minimum here. So a general name for this MOS pattern could be "mavila superdiatonic" or simply 'Superdiatonic'.

|
| These scales are strongly associated with [[mavila]] system, which can be divided into two systems:
| | == Theory == |
| * the [[Armodue|Armodue]] project/system and its associated [[armodue]] temperament, with fifths sharper than 5\9 (666.7¢) and flatter than 9\16 (675¢).
| | === Temperament interpretations === |
| * Hornbostel temperament, with fifths sharper than 9\16 (675¢) and flatter than 4\7 (685.71¢).
| | [[Pelogic family#Mavila|Mavila]] is an important harmonic entropy minimum here, insofar as 670-680{{c}} can be considered a fifth. Other temperaments include septimal mavila, hornbostel, and trismegistus. |
|
| |
|
| Some high JI approximations of the generator: 31/21, 34/23, 65/44, 71/48, 99/67, 105/71, 108/73, 133/90, 145/98, 176/119, 250/169. These could be used to guide the construction of neji versions of superdiatonic scales or edos.
