1-3-5-9-15 dekany

Circle diagram.

Circle diagram (rotated).

The simplest 5-limit dekany. This creates a scale of 1 9/8 5/4 45/32 3/2 25/16 5/3 15/8, with steps of 9/8 10/9 9/8 16/15 25/24 16/15 9/8 16/15. This is notable because it is the simplest dekany that winds up with only 8 notes, with 5/4 appearing twice as the reduced product of 1x15 & 3x5 and 15/8 appearing twice as the reduced product of 3x15 & 5x9. This is an unambiguous detemper of the lydian mode of the diatonic scale with a single extra note added on. Since this is one of the least xenharmonic dekanies and relatively limited in compositional options as well, this is easy to work with but not particularly interesting.
