Original Wikitext content:
In the theory of [[Margo Schulter]], //interseptimal// is a category of intervals which occupy regions intermediate between two septimal ratios such as [[8_7|8/7]] and [[7_6|7/6]], or [[12_7|12/7]] and [[7_4|7/4]]. There are four interseptimal regions given below, with approximate cents ranges from Schulter's article [[http://www.bestii.com/%7Emschulter/IntervalSpectrumRegions.txt|Regions of the Interval Spectrum]]: # Maj2-min3, 240¢-260¢ # Maj3-4, 440¢-468¢ # 5-min6, 732¢-760¢ # Maj6-min7, 940¢-960¢ Interseptimal intervals are well-represented in [[24edo]] at 250¢, 450¢, 750¢ and 950¢. As they fall in ambiguous zones between simpler categories, they are inevitably xenharmonic. See: [[Interval Categories]], [[Gallery of Just Intervals]]
