-'''Father''' may refer to:
+{{About|the regular temperament|the scale structure sometimes associated with it|5L 3s}}
-* a low-accuracy 2.3.5 temperament that generates a 5L 3s scale; see [[Trienstonic clan #Father]]
-* (a misnomer for) [[5L 3s]] aka oneirotonic, a [[MOS]] scale and its associated musical framework
-{{Disambiguation}}
+'''Father''' is a very coarse, simplistic [[exotemperament]]. It [[Tempering out|tempers out]] [[16/15]], the classical diatonic semitone. This means the [[5/4|classical major third (5/4)]] is conflated with the [[4/3|perfect fourth (4/3)]], making it one that challenges the very notion of JI approximation, and playing harmony in it, it sounds only remotely reminiscent of the [[5-limit]] no matter how it is tuned. If one could get their head around this way of hearing intervals, they may as well take a look at the 7-limit interpretation, where it tempers out [[28/27]] and [[36/35]].
+The main interest in this temperament is in its [[mos scale]]s, featuring [[3L 2s|antipentic (3L 2s)]] and [[5L 3s|oneirotonic (5L 3s)]] when properly tuned. It is likely the case that those scales are often chosen first, and only later is each step associated with a ratio consistent with this temperament.
+See [[Father family #Father]] and [[Trienstonic clan #Father]] for technical details.
