| The '''Electrum temperaments''' are a group of rank-2 temperaments proposed by Iwuqety, inspired by the idea of using the [[acoustic phi]] (golden ratio <nowiki><math>\varphi</math></nowiki>) and acoustic silver ratio <nowiki><math>δ</nowiki><sub>s</sub><nowiki></math></nowiki> as generators, respectively replacing the [[3/2]] perfect fifth and the [[2/1]] octave used in common practice music. [[wikipedia:Electrum|Electrum]] refers to naturally-occurring alloy which is mainly made up of gold and silver.
