just intonation
C2+ (Very Low / Specialist)Technical / Academic / Music Specialist
Definition
Meaning
A musical tuning system where intervals are derived from the harmonic series, producing pure, acoustically perfect intervals with simple integer frequency ratios.
A historical and modern practice of tuning musical instruments based on natural harmonics, often contrasted with equal temperament; used in early music performance, contemporary experimental music, and theoretical discussions of consonance.
Linguistics
Semantic Notes
The term 'just' here relates to 'purity' or 'perfection' in an acoustic/mathematical sense, not moral justice. Often used in opposition to 'tempered intonation' or 'equal temperament'.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or semantic differences. Slight variance in pronunciation.
Connotations
Identical technical connotations in both music theory and performance contexts.
Frequency
Equally rare and specialised in both varieties, confined to music academia, professional musicianship, and specific enthusiast circles.

Learning
Memory Aids
Mnemonic
Think: 'JUST the RIGHT notes' – this tuning uses the 'just' or exact mathematical ratios from nature's harmonic series.
Conceptual Metaphor
PURITY / NATURALNESS (Pure intervals from nature) vs. COMPROMISE / ENGINEERING (Equal temperament as a man-made compromise).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'just' as 'просто' or 'только'. The correct conceptual translation is 'чистый строй' or 'натуральный строй'.
- Do not confuse with 'интонация' meaning speech intonation. Here it specifically refers to musical pitch/tuning systems.
Common Mistakes
- Mispronouncing 'just' with a strong /dʒʊst/ as in 'justice'; the vowel is a schwa /ə/ in connected speech: /dʒəst/.
- Using it to describe being 'in tune' in a general sense, rather than referring to the specific mathematical system.
- Confusing it with 'just' as an adverb ('just intonation' vs 'just play in tune').

FAQ
Frequently Asked Questions
No, to an ear accustomed to it, it can sound more 'in tune' or pure within a specific key, but chords may sound dissonant when modulating (changing key) because the interval relationships shift.
Not practically, because a piano's fixed pitches are set during tuning. Just intonation requires flexible tuning for different keys or even different chords within a piece. Specialised electronic keyboards or fretless/flexible instruments can use it.
Yes, by composers and musicians in experimental, microtonal, and some folk traditions. It's also fundamental to the theory behind barbershop quartet singing and certain styles of harmonic vocal blending.
The term comes from the concept of a 'just' or 'pure' interval, one whose frequencies form a simple whole-number ratio (e.g., 3:2 for a perfect fifth), which is naturally occurring in the harmonic series.
