1-5-7-11 hexany
The simplest possible no-3's Hexany. This creates a scale of 1 11/10 11/8 7/5 7/4 77/40 2/1, with steps of 11/10 5/4 56/55 5/4 11/10 80/77. With a ratio of more than 12:1 between the largest and smallest steps, this is a very lopsided hexany filled with unfamiliar melodic movements. The most stable root is probably the 11/10, which has a 4:5:7 chord above it.
