1-3-5-9 by 27/20 bihexany

The second simplest possible Hexany, offset by a wolf fourth. This creates a scale of 1 81/80 9/8 5/4 81/64 27/20 3/2 243/160 5/3 27/16 15/8 2/1, with steps of 81/80 10/9 10/9 81/80 16/15 10/9 81/80 800/729 81/80 10/9 16/15. This is the most complex way of expanding the base hexany out that has any duplicated notes, reducing it to a 11 note scale. This does give it a complete diatonic scale, but now four of the notes have multiple variants a comma step apart, which means you can evade wolf notes by playing the correct ones in chords, but also have a wide range of complex and subtle dissonances available if you intentionally choose the wrong notes that make this capable of far more than simply making songs composed using the diatonic scale sound more in tune.
