'''26edo''' divides the [[octave]] into 26 equal parts of 46.154 [[Cent|cents]] each. It tempers out 81/80 in the [[5-limit]], making it a meantone tuning with a very flat fifth. | |||

In the [[7-limit]], it tempers out 50/49, 525/512 and 875/864, and supports [[injera]], [[flattone]], [[Jubilismic clan#Lemba|lemba]] and [[Jubilismic clan#Doublewide|doublewide]] temperaments. It really comes into its own as a higher-limit temperament, being the smallest equal division which represents the [[13 odd limit]] [[consistent|consistently]]. 26edo has a very good approximation of the harmonic seventh ([[7/4]]). | |||
26edo's "minor sixth" (1.6158) is very close to φ ≈ 1.6180 (i. e., the golden ratio). | 26edo's "minor sixth" (1.6158) is very close to φ ≈ 1.6180 (i. e., the golden ratio). |
