Copper comma: Difference between revisions

Line 7:

'''Copper comma''', or alternately '''29-atom''' is a 5-limit comma which is to [[29edo]] as is the Kirnberger's atom is to [[12edo]].

==Temperaments==

Tempering it out results in the rank-2 '''copper''' temperament, which splits the octave into 29 parts, and the reduced generator is the difference between a more precise fifth and the 29-tone-tempered one, just as [[atomic]] does to 12edo.

Tempering it out results in the rank-2 '''copper''' temperament, which splits the octave into 29 parts, and the reduced generator is the difference between a more precise fifth and the 29-tone-tempered one, just as [[atomic]] does to 12edo. See: [[29th-octave temperaments#Copper]].

A circle of 29 of the sharpened fifths equal to 98415/65536 (monzo: {{monzo|-16 9 1}}), differs from 17 octaves by the copper comma. The difference is that since 29edo is an above-pythagorean temperament, the copper fifth is sharp of 3/2. Notably, in the case of copper, the comma which sharpens the fifth to be close to 29edo's is still the [[schisma]], 32805/32768.
