This page presents a novelty topic.
It may contain ideas which are less likely to find practical applications in music, or numbers or structures that are arbitrary or exceedingly small, large, or complex. Novelty topics are often developed by a single person or a small group. As such, this page may also contain idiosyncratic terms, notation, or conceptual frameworks. |

1330edo is enfactored in the 7-limit and has the same tuning as 665edo. It corrects 665edo's approximation of harmonic 11, only to be consistent up to the 11-odd-limit, unfortunately. It tempers out 3025/3024, 9801/9800, and 234375/234256, supporting hemienneadecal, though 1178edo is a better tuning for that purpose.
