'''Shallowtone''' is a [[~~5-limit~~]] ~~and higher~~ [[~~temperament~~]] ~~which tempers out the~~ [[~~shallowtone comma~~]]. It is generated by a ~~flat~~ fifth, ~~which is~~ typically sharper than in [[mavila]] but flatter than in [[7edo~~]]. This gives it a high [[error~~]], ~~although not as much as mavila. The ~~~[[5/4]] is reached by minus ten fifths octave-reduced, which is an augmented third (~~C-Ex~~) in melodic antidiatonic notation and a diminished third (~~C-Ebb~~) in harmonic antidiatonic notation. The only reasonable extension to the 7-limit tempers out [[36/35]]. Additionally, there is a weak extension [[Greenwoodmic temperaments#Semishallowtone|semishallowtone]] with a half-octave period, tempering out [[405/392]].

'''Shallowtone''' is a [[regular temperament|temperament]] where the [[shallowtone comma]] is [[tempering out|tempered out]]. It is generated by a flattened [[3/2|perfect fifth]], typically sharper than in [[mavila]] but flatter than in [[7edo]], and [[5/4]] is reached by minus ten fifths [[octave reduction|octave-reduced]], which is an augmented third (C–E𝄪) in melodic antidiatonic notation and a diminished third (C–E𝄫) in harmonic antidiatonic notation. This gives it a high [[error]], although not as much as mavila.

The only reasonable [[extension]] to the [[7-limit]] tempers out [[36/35]]. Additionally, there is a weak extension [[Greenwoodmic temperaments #Semishallowtone|semishallowtone]] with a half-octave period, tempering out [[405/392]].

The name was coined by [[User:CompactStar|CompactStar]] in 2024. It refers to how it is an opposite to [[deeptone]] (which is on the other side of 7edo), as well as because it is just below the diatonic "surface".
