=== Tridec (29&37) ===
=== Tridec (29&37) ===
In the broad sense, Tridec can be viewed as any oneirotonic tuning that equates three oneirotonic large steps make a [[4/3]] perfect fourth. [This identification may come in handy since some altered oneirotonic modes have three large steps.] Based on the tuning's [[29edo]] and [[37edo]] interpretations, it can in fact be viewed as a 2.3.7/5.11/5.13/5 temperament, i.e. a [[Non-over-2 temperament|non-over-2 temperament]] that approximates the chord 5:7:11:13:15. The optimal generator is 455.2178c, which is very close to 29edo's 11\29 (455.17c), but we could accept any generator between 17\45 (453.33c) and 8\21 (457.14c), if we stipulate that the 3/2 has to be between [[7edo]]'s fifth and [[5edo]]'s fifth.

The sizes of the generator, large step and small step of oneirotonic are as follows in various tridec tunings.
