<p><b>New page</b></p><div>[[File:1-3-5-9_by_6-5_bihexany.png|thumb|Circle diagram.]] The second simplest possible [[Hexany]], offset by a minor third. This creates a scale of 1 9/8 6/5 5/4 27/20 3/2 5/3 9/5 15/8 2/1, with steps of 9/8 16/15 25/24 27/25 10/9 10/9 27/25 25/24 16/15. This is the second most repetitive way of expanding the [[1-3-5-9 hexany|base hexany]] out, with three duplicated notes reducing it to a 9 note scale. It does have 6 perfect fifths and a complete diatonic scale, but it also has two wolf fifths that are out by a [[syntonic comma]], which means standard chord progressions that work with no problems in 12edo can run into issues here. If you want a scale that has the same pattern of notes, but lacks the duplicated ones, extending it to a full 12 note scale, use the [[1-3-5-9 by 25/18 bihexany]].<br />
