== Extensions ==
For technical data, see [[Very low accuracy temperaments #Antonian]].
There are some extensions of antonian, including septimal antonian ({{nowrap|2cd &amp; 3d}}), antonym ({{nowrap|2cd &amp; 3}}), antony ({{nowrap|2c &amp; 3d}}), and phlegyas ({{nowrap|2c &amp; 3}}).


In the septimal antonian, [[7/6]] is equated to 5/4 and 9/8, by tempering out [[15/14]] and [[28/27]]. Antonym tempers out [[7/6]] and [[21/20]]. Antony tempers out [[8/7]] and [[36/35]]. Phlegyas tempers out [[35/32]] and [[64/63]].

This page presents a topic of primarily mathematical interest.

While it is derived from sound mathematical principles, its applications in terms of utility for actual music may be limited, highly contrived, or as yet unknown.

Antonian is an exotemperament that tempers out 10/9, the classic major second. This equates 3/2 with 5/3, 4/3 with 6/5, and 5/4 with 9/8, being even less accurate than more common archetypal exotemperaments like father or dicot. It can be represented by only 3edo in its patent val.

In septimal antonian, 7/6 is equated to 5/4 and 9/8, by tempering out 15/14 and 28/27. An alternative extension is phlegyas, which tempers out 35/32 and 64/63, so 8/7 is equated with 5/4 and 9/8 instead.

For technical data, see Very low accuracy temperaments #Antonian.
