Submerged is a temperament generated by a sharply tuned minor sixth (or its octave complement, a flatly tuned major third, adopted by this article for a comparison with magic), tempering out the submerged comma in the 5-limit. The major third is slightly flat of magic's major third, which itself is slightly flat of a just 5/4, making submerged's generator arguably a submajor third. The comma's monzo is [-27 1 11⟩, which implies that eleven 8/5's minus seven octaves stack to make a 3/2, thus making its ploidacot zeta-hendecacot.

For limits higher than 5, nine 5/4's stack to reach 7/4, and it tempers out 525/512 and 3125/3087 in the 7-limit, and in the 11-limit, 441/440 and 121/120. In the 13-limit, in addition to tempering out 105/104, if we look at a submerged third, it sits in between 16/13 and 5/4, and a very logical thing to do is to temper out the difference between these two intervals, thus also tempering out 65/64.

Possible tunings include 16edo, 29edo, and 45edo.

Submerged was named by Fitzgerald Lee as a play on the term "submajor third".

See Avicennmic temperaments #Submerged for technical data.
