'''The ocean''' is a group of temperaments related to [[schismic]] in the same way [[deeptone]] and [[mavila]] relate to [[meantone]].
'''The ocean''' is a group of temperaments related to [[schismic]] in the same way [[deeptone]] and [[mavila]] relate to [[meantone]].


While mavila, meantone and deeptone equate [[5/4]] to a third, ocean temperaments equate it to a (usually diminished) fourth. The number of times the fourth must be diminished to get to ~5/4 is known as the depth of the temperament.

As such, this is an [[equivalence continuum]]. The natural name for it would be something like diatonic-chromatic, due to its equating a certain number of [[2187/2048]] Pythagorean chromatic semitones to a [[16/15]] pental diatonic semitone, but that is already taken by the [[father-3 equivalence continuum]]. It could be apotome-diatonic, but the ocean just sounds like a better name.

It could be apotome-diatonic, but, as all of these temperaments are supported by 7c, the term "ocean" works.


Some of these temperaments are already named (especially those with low depth), but those with higher depth are not.
Some of these temperaments are already named (especially those with low depth), but those with higher depth are not. As such, a series of names based on ocean stratification has been chosen.

While, with positive depth, the fifth gets flatter and flatter, with negative depth, it gets sharper and sharper, converging to 4\7 in each case.
Beyond hadal, there are no more patent vals (the next temperament being the vaguely ridiculous 47cc & 54b). As such, it is a natural place to stop.
