Despite being none other than the tripled superset of the famous 53edo, and hence, one would think, fairly easy to find, it is a wonder that the first person to show theoretical interest in it was [[Ozan Yarman]]—specifically in terms of extracting a voluminous subset for representing maqamat—in late 2005 to early 2006. | Despite being none other than the tripled superset of the famous 53edo, and hence, one would think, fairly easy to find, it is a wonder that the first person to show theoretical interest in it was [[Ozan Yarman]]—specifically in terms of extracting a voluminous subset for representing maqamat—in late 2005 to early 2006. | ||

Accordingly, it is no coincidence that [https://en.xen.wiki/index.php?title=159edo&type=revision&diff=5153&oldid=5154 the first records of 159edo on this Wiki from the days of Wikispaces] concern said 79-tone subset related to the [[Turkish maqam music temperaments|yarman]] temperament which had been proposed by Yarman as a tuning standard for [[Arabic, Turkish, Persian music|Arabic, Turkish and Persian music]]. Based on the information given by Ozan Yarman himself, his elder colleague [[M. Ugur Kececioglu]] first utilized 159edo in his revamped 2011 release of the [[Notist]] score editor and therein allowed the Arel-Ezgi-Uzdilek (AEU) accidentals to be bent by as little a detail as 1/3 of a single step of 53edo, while also mapping AEU altogether to a suitable subset of 53edo to allow transpositions throughout. | Accordingly, it is no coincidence that [https://en.xen.wiki/index.php?title=159edo&type=revision&diff=5153&oldid=5154 the first records of 159edo on this Wiki from the days of Wikispaces] concern said 79-tone subset related to the [[Turkish maqam music temperaments|yarman]] temperament which had been proposed by Yarman as a tuning standard for [[Arabic, Turkish, Persian music|Arabic, Turkish and Persian music]].

A salient fact about 159edo is that {{nowrap| 159 {{=}} 3 × 53 }}, and thus, this system has both [[3edo]] and [[53edo]] as subsets—the former subset being shared with [[12edo]]. | |||
