Original Wikitext content:
=18 Equal Divisions of the Octave= ==Basis== ===<span style="font-size: 13px; font-weight: normal; line-height: 19px;"> </span>=== ===**Representations of Just Intervals**=== <span style="font-size: 14px; line-height: 21px;">**Relationship to Other EDOs** </span> 18-EDO, aka the "third-tone" system, is related to 12-tET by the whole-tone scale (which is 6-EDO), since 18=6*3 and 12=6*2; hence a 12-tET "whole tone" is divided into 3 equal parts in 18-EDO. Since 18=9*2, 18-EDO contains two sets of 9-EDO, offset from each other by a third-tone. ===Representations of Linear Temperaments=== === ===
