The 5-odd-limit is the set of all rational intervals for which neither the numerator nor the denominator of the frequency ratio exceeds 5, once all powers of 2 are removed. To the 3-odd-limit, it adds 2 interval pairs involving 5.

Below is a list of all octave-reduced intervals in the 5-odd-limit.

Ratio Size (¢) Color name Name
6/5 315.641 g3 gu 3rd minor third
5/4 386.314 y3 yo 3rd major third
8/5 813.686 g6 gu 6th minor sixth
5/3 884.359 y6 yo 6th major sixth

The smallest equal division of the octave which is consistent in the 5-odd-limit is 3edo; that which is distinctly consistent in the same is 9edo.
