<p>A little calendar inspired dekany to celebrate the anniversary of my starting the combination product set drive.</p> <p><b>New page</b></p><div>[[File:1-3-7-31-365_dekany.png|thumb|Circle diagram.]] A [[73-limit]] [[dekany]]. This creates a scale of 1 1 217/192 7/6 31/24 365/256 2555/1536 7/4 11315/6144 365/192 31/16 2/1, with steps of 217/192 32/31 31/28 1095/992 7/6 384/365 11315/10752 32/31 372/365 32/31. This is inspired by the numbers in the calendar, combining the no-2&#039;s factors of days of the week, days in a month, days in a year and months in a year. This produces an interestingly xenharmonic scale that is somewhat clustered at the end, but still has three perfect fifths that can be used to provide points of stability and only one step that is so small it blurs into its neighbour, making it quite effective melodically despite its complexity.<br /> <br /> &lt;pre&gt;<br /> ! 1-3-7-31-365_Dekany.scl<br /> !<br /> 1 3 7 31 365 2-combination Dekany<br /> 10<br /> !<br /> 211.906<br /> 266.871 <br /> 443.080<br /> 614.103<br /> 880.974<br /> 968.825<br /> 1057.183<br /> 1112.148<br /> 1145.035<br /> 1200<br /> &lt;/pre&gt;<br /> <br /> Suggested keyboard mapping: C D D# E F# G G# A A# B C.<br /> <br /> [[Category:Dekanies]]<br /> [[Category:10-tone scales]]<br /> [[Category:Pages with Scala files]]</div>
