7-11-13-15 hexany
A 15-odd-limit Hexany. This creates a scale of 1 15/14 13/11 195/154 15/11 13/7 2/1, with steps of 15/14 182/165 15/14 14/13 143/105 14/13. Like several of its close relatives, this is quite melodically effective, but only covers half the octave, with a large gap on the other side, which does at least mean it can be expanded into a bihexany using any interval near 600 cents with a minimal amount of note overlap.
