1-3-5-9 by 16/15 bihexany
The second simplest possible Hexany, offset by a minor second. This creates a scale of 1 16/15 9/8 6/5 5/4 4/3 3/2 8/5 5/3 16/9 15/8 2/1, with steps of 16/15 135/128 16/15 25/24 16/15 9/8 16/15 25/24 16/15 135/128 16/15. This is the simpler of two different ways of expanding the base hexany out that has one duplicated note, reducing it to a 11 note scale. It turns it from a near complete diatonic scale to a near complete chromatic scale with 8 perfect fifths and two wolf ones. This means most common practice music can be translated to it, but due to the longer chain of perfect fifths in the centre, some of the thirds are pythagorean, while others are 5-limit, which means the character of a song will change dramatically if you transpose it to a different key.
