<p><b>New page</b></p><div>[[File:3-5-7-13-15_Dekany.png|thumb|Circle diagram.]] A [[15-odd-limit]] [[dekany]]. This creates a scale of 1 13/12 7/6 5/4 13/10 7/5 3/2 91/60 13/8 7/4 2/1, with steps of 13/12 14/13 15/14 26/25 14/13 15/14 91/90 15/14 14/13 8/7. Like any dekany derived from the [[3-5-7-15 hexany]], this has a rich selection of simple intervals available, including a full harmonic seventh chord over the root. The addition of ratios of 13 gives you several other good chords, but also one awkward small step of 91/90. It has three perfect fifths, plus an additional one that is flat by [[105/104]], but they are all one one side of the scale, which somewhat limits your modulation options. Still, overall, this is pretty good when taken as a nonatonic scale, only introducing major clashes when that comma step is used.<br />
