[[Category: | Tempering out this comma alone in the 11-limit results in the rank-4 '''frostmic temperament''' (→ [[Catalog of rank-4 temperaments #Frostmic (245/242)]]), where a stack of two [[11/7]]'s is equated with a [[5/2]] major tenth, enabling [[frostmic chords]]. | ||

== Etymology == | |||
This comma was named after [[User:Frostburn|Frostburn]] in 2022. Before it got the name ''frostma'', it was known as the ''cassacot'', probably derived from [[cassandra]] and [[tetracot]]. However, ''cassandra'' was a misnomer for [[andromeda]]. The temperament's name was later corrected. Since then, ''cassacot'' has lost its root, thus justifying the new name. | |||
