The bronzisma, 2097152/2083725, is a 7-limit comma. It is the difference between a classic chromatic semitone of 25/24 and three septimal commas.


Tempering out this comma results in the rank-3 bronzismic temperament in the 7-limit. Together with the septimal semicomma it produces amigo temperament, and together with 3136/3125 it produces decipentic temperament.

It is also tempered to one step of 118edo in the 7-limit temperament oganesson, although it is not the most precise mapping (compared to 13-limit 169/168 and 17-limit 170/169), as there are directly roughly 108 bronzismas in the octave.


This comma was named by Xenllium in 2021.
