Minor seventh
In just intonation
By prime limit
The Pythagorean (3-limit) minor seventh is 16/9, which is 996 ¢ in size and corresponds to the mos-based interval category of the diatonic minor seventh. It is generated by stacking two just perfect fourths of 4/3.
Other major seconds exist in higher limits:
- The 5-limit ptolemaic minor seventh is a ratio of 9/5, however in 5-limit harmony it is used alongside 16/9. It is about 1018 ¢.
- The 7-limit (septimal) subminor seventh, harmonic seventh, or overtone seventh is a ratio of 7/4, and is about 969 ¢.
