<p><b>New page</b></p><div>[[File:1-3-7-9-11-13_Eikosany.png|thumb|Circle diagram.]] A [[13-odd-limit]] [[eikosany]]. This creates a scale of 1 33/32 117/112 13/12 9/8 33/28 39/32 143/112 9/7 11/8 39/28 143/96 3/2 11/7 13/8 143/84 99/56 11/6 13/7 429/224 2/1, with steps of 33/32 78/77 28/27 27/26 22/21 91/88 22/21 144/143 77/72 78/77 77/72 144/143 22/21 91/88 22/21 27/26 28/27 78/77 33/32 448/429. With 5 close comma steps that blur into one-another, this is not particularly optimal for its size melodically, but as it still has 12 perfect fifths and plenty of other simple harmonic resources, it is still quite possible to play recognisable music in it as long as you know how to use the septimal and gentle thirds correctly.<br />
