Relative cent: Difference between revisions

Line 5:

Given any ''N'' [[EDO]], the size of an interval in ''relative cents'' is ''N''/12 times its size in [[cent]]s; or equivalently, 100 ''N'' times its logarithm base 2. Hence in [[7edo|7EDO]], the octave is 700 relative cents, in [[53edo|53EDO]], 5300 relative cents and so forth.

An existing example is the [[turkish cent]], which is the relative cent of [[106edo|106EDO]]. The iota, the relative cent for [[17edo|17EDO]], has been proposed by [[George Secor]] and [[Margo Schulter]] for use with 17EDO, and [[Tútim Dennsuul Wafiil|Tútim Dennsuul]] has advocated the [[purdal]], which divides the octave into 9900 parts (being relative cents of [[99edo|99EDO]]). The [[millioctave]] is another such measure, as it can be viewed as the relative cent measure for [[10edo|10EDO]]. The ~~sat~~, for use with Armodue, divides the octave into 1600 parts (Armodue being a theory of [[16edo|16EDO]]).
