	[[File:3-5-7-9-15_Dekany.png\|thumb\|Circle diagram.]] A [[15-odd-limit]] [[dekany]]. This creates a scale of 1 21/20 9/8 7/6 5/4 7/5 3/2 7/4 9/5 2/1, with steps of 21/20 15/14 28/27 15/14 28/25 15/14 8/7 36/35 10/9. (3/2 appears twice as the reduced product of 3x15 and 5x9) While slightly reduced in compositional options compared to the average dekany, the ones it does have are filled with simple ratios and easy to use chords, including four perfect fifths and the full harmonic series up to 10 above the root note, making it highly accessible to casual users.
