<p><b>New page</b></p><div>[[File:1-3-5-9-11-15_Eikosany.png|thumb|Circle diagram.]] A [[15-odd-limit]] [[eikosany]]. This creates a scale of 1 33/32 11/10 9/8 99/80 5/4 11/8 45/32 3/2 99/64 33/20 27/16 55/32 9/5 11/6 15/8 2/1, with steps of 33/32 16/15 45/44 11/10 100/99 11/10 45/44 16/15 33/32 16/15 45/44 55/54 288/275 55/54 45/44 16/15. (3/2, 9/8, 11/8 and 33/32 appear twice, reducing it to a 16 note scale) Like many scales in this prime subgroup, this is a [[porcupine]] detemper, clustering around a heptatonic scale with multiple close notes on each degree. Only the 100/99 step is so small as to be melodically troublesome and there are many strong chord combinations, with at least one perfect fifth in every cluster to root chords upon, giving you plenty of freedom to modulate. <br />
