The simplest and most consonant [[chord]] mathematically possible which contains three notes. It only contains two [[Pitch class|pitch classes]], so it is classified as a [[dyad]]; and is the simplest inversion of a [[2:3|power chord]].
 
It is approximated with less than two cents of total error in [[12edo]], so it may be used to create an open, stable, and powerful sound in western composition.
 
Temperaments and EDOs which favor the third harmonic, most notably 12edo and [[29edo]], will approximate this chord quite well. Likewise, temperaments like superpyth and meantone, which do not favor the third harmonic, will approximate this chord more poorly.
