The concept of "fendo" tuning is well-represented by EDOs 8, 13, and 18. Each pair of these produces a rank-2 temperament in 2.3.5.13 separating 13/8 and 5/4 by 3/2 (octave-reduced):
The concept of "fendo" tuning is well-represented by [[EDOs]] {{EDOs|8, 13, and 18}}. Each pair of these produces a rank-2 temperament in 2.3.5.13 separating 13/8 and 5/4 by 3/2 (octave-reduced), or equivalently tempering together 13/8 and 5/3. They differ from unintendo in that [[5/4|5]] is found somewhere along the [[chain of fifths]] rather than being its own [[generator]].

To reach 5/4 you stack 7 generators and to reach 13/8 you stack six. 5/4 is tuned sharp; 13/8 is also sharp.
To reach 5/4 you stack 7 generators and to reach 13/8 you stack six. 5/4 is tuned sharp; 13/8 is also sharp.
In terms of circle of fifths notation, 5 is the [[chromatic semitone]] and 13 is the augmented fourth.

To reach 5/4, you go down 6 generators. To reach 13/8, you go down 7 generators. Both 5 and 13 are sharp.
To reach 5/4, you go down 6 generators. To reach 13/8, you go down 7 generators. Both 5 and 13 are sharp.
In terms of circle of fifths notation, 5 is the diminished fifth and 13 is the diminished octave.
