It's clearly seen, that the 70—80 cent interval is C to C#, or an augmented unison.

Unsure how to respond with a private message here, but you can get me easier on Facebook if you have it. | |||
C-C#, or an augmented unison is only the small semitone where perfect fifths are less than 700c. In every tuning where the perfect fifth is more than 700c (as here), the interval from C-C# will be greater than the interval from C#-D (minor second). This includes 17, 22, 27, 29, 34, 37, 41, 44, 46edos, which are not meantone tunings, like those you referred to, where the augmented unison is indeed the smaller semitone and the minor second the larger part. That is the case for all tunings within (4\7, 7\12), "negative tunings", as opposed to the "positive tunings" with fifths between (7\12, 3\5). Hope this helps to clarify. -Cam | |||
