1-odd-limit
The 1-odd-limit is the set of all rational intervals which can be written as 2k(a/b) where a, b ≤ 1 and k is an integer.
Below is a list of all octave-reduced intervals in the 1-odd-limit. The 1-odd-limit contains only the unison (and all it's octavations). It is equivalent to the 2-limit (prime limit).
