The 3-odd-limit is the set of all rational intervals which can be written as 2k(a/b) where a, b ≤ 3 and k is an integer. To the 1-odd-limit, it adds 1 pairs of octave-reduced interval involving 3.

Below is a list of all octave-reduced intervals in the 3-odd-limit.

Ratio Size (¢) Color name Name
4/3 498.045 w4 wa 4th just perfect fourth
3/2 701.955 w5 wa 5th just perfect fifth

All edos are consistent in the 3-odd-limit, since there are only two pitch classes besides the octave. The density of edos consistent in the 3-odd-limit to distance d is expected to be 1/d for d ≥ 1.
