Harmonics 33–66
The harmonics 33–66 (also harmonic series segment 33::66 or harmonic series mode 33) are a scale that consists of harmonics 33 through 66 (33:34:…:66) and repeats at the octave. Used as a tuning system, it is also called 33afdo. It is also the first odd-numbered mode to have a diatonic fifth from its root, although for both fifths to be diatonic, harmonics 37–74 is necessary.
