# just-intonation_{(tuning-theory)}

Roughly speaking a just intonation system is a system where the intervals are whole number ratios of frequencies. For example 12-tone equal temperament is not a just intonation system because its ratios are multiples of 1:2^{(1/12)}.

(Basically, all equal temperaments are not just intonation system. )
