=**Theory**= 

8-edo forms an odd and even pitch set of two diminished seventh chords, which when used in combination yield dissonance. The system has also been described as a "barbaric" harmonic system; however, it does a good job representing the [[just intonation subgroup]] 2.11/3.13/5, with good intervals of 13/10 and an excellent version of 11/6.
