72-tone equal temperament (or 72-edo) divides the octave into 72 steps or &lt;em&gt;moria&lt;/em&gt;. This produces a twelfth-tone tuning, with the whole tone measuring 200 cents, the same as in 12-tone equal temperament. 72-tone is also a superset of &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/24edo"&gt;24-tone equal temperament&lt;/a&gt;, a common and standard tuning of &lt;a class="wiki_link" href="http://xenharmonic.wikispaces.com/Arabic%2C%20Turkish%2C%20Persian"&gt;Arabic&lt;/a&gt; music, and has itself been used to tune Turkish music.&lt;br /&gt;
