A tuning system based on simple mathematical ratios between frequencies, producing pure harmonic intervals. This system creates beatless consonances but makes modulation between keys difficult.
From 'just' meaning 'exact' or 'pure' and 'intonation' meaning 'tuning.' The term distinguishes this mathematically precise system from equal temperament, which slightly adjusts all intervals for practical purposes.
Just intonation is music's pursuit of mathematical perfection - when instruments are tuned to exact frequency ratios like 3:2 for a perfect fifth, the harmonies ring with an almost supernatural purity that equal temperament can never achieve, which is why some contemporary composers are returning to these ancient tuning principles!
