The harmonics 6–12 (also harmonic series segment 6::12 or harmonic series mode 6) are a scale that consists of harmonics 6 through 12 (6:7:8:9:10:11:12) and repeats at the octave. Used as a tuning system, it is also called 6afdo. In its root position, it is an effective system that contains several useful intervals such as 7/6, 4/3 and 3/2, although it lacks a major third.
