This page is fine, and certainly an improvement over what I wrote a long time ago.

I did want to add, however, that the AIS series can be grouped into 267 groups, if you include together the transpositions, retrogrades, 5ms, and rotations. These are all "easy" operations -- in the sense that they are intuitive, or easily done by hand. This information is given by the Morris and Starr paper.

As for a "hand algorithm" that will generate all the all-interval series, no one has yet found one.

After the Morris and Starr paper, the next place that has useful insights is the paper by Mead. There's also a Part Two.

^ Mead, Andrew (1988). "Some Implications of the Pitch Class-Order Number Isomorphism Inherent in the Twelve-Tone System- Part One". Perspectives of New Music 26 (2): 96–163. doi:10.2307/833188. JSTOR 833188.

And one final source of information that certain determined folk might find useful. I put together a database listing all the AIS from the Morris and Starr paper. It lists all 267 of the groups. The way the information is set up, you can instantly find a given AIS with a simple string search.

available here: https://app.box.com/s/cut64o6uvczortj01f2c

This text file has some other information which would require some explanation. But it links each group of 267 families with some of the well-known AIS, such as those mentioned by Slonimsky, and some of the AIS generated by formulas such as 2 ^ n mod 13.

Anyone is free to use it for any purpose aside from making piles of cash, or aside from world domination.

Contact me if you have any reasonable questions about it:

This page has some problems: Carter's concept of a twelve-tone chord (spatial intervals, or a registrally ordered set) should be clearly distinguished. In the intro it is conflated with the serial idea. But Carter's usage is aesthetically totally different than the usage in "classic" serialism.

There are many useful properties of the all-interval series that could be mentioned in a section devoted to that topic and linked with other 12-tone theory articles. For example, the fact that the tritone must occur in the middle, retrograde symmetry, and combinatoriality.

On Wikipedia, everybody is an editor. By all means implement these changes yourself, but do try to find reliable sources to support any statements that may not be blindingly obvious to any reader with no background in the subject.—Jerome Kohl (talk) 15:39, 3 October 2014 (UTC)[reply]
