* 240¢-260¢ -- semifourth -- an interval of this size is around half the size of a perfect fourth. [[User:IlL|Inthar]] proposes the name '''lygic''' (from Greek ''lygē'', twilight) for this region.

* 440¢-468¢ -- semisixth -- an interval of this size is around half the size of a major sixth. [[Zhea Erose]] calls the 440c-464c region '''naiadic''' (from ''naiad'', a kind of ancient Greek water spirit) and uses it frequently.

* 732¢-760¢ -- semitenth -- an interval of this size is around half the size of a major tenth (i. e., compound major third). Another possible name is sesquifourth (since this is also about one and a half times the size of a perfect fourth). [[User:IlL|Inthar]] proposes the name '''cocytic''' (from Dante's Cocytus, the frozen lake in the underworld).

Another possible name is sesquifourth (since this is also about one and a half times the size of a perfect fourth). [[User:IlL|Inthar]] proposes the name '''cocytic''' (from Dante's Cocytus, the frozen lake in the underworld; chosen because it's an inverse naiadic).

* 940¢-960¢ -- semitwelfth -- an interval of this size is around half the size of a perfect twelfth (i e., a compound perfect fifth, or tritave). All even [[edt|edts]] have a semitwelfth of approximately 951 cents, analogous to the 600 cent tritone shared by all even edos. [[User:IlL|Inthar]] proposes the name '''obsidic''' for this region.
