The musical interval of a minor third is the relationship between the first note (the root or tonic) and the third note in a minor scale. It is the inversion of the Major sixth. It can be produced by starting on a high note and playing the third below or by starting on a low note and playing the third above. It is abbreviated as m3.
A minor third in just intonation most often corresponds to a pitch ratio of 6:5 (or 1:1.2), or various other ratios. while in an equal tempered tuning, a minor third is equal to three semitones, a ratio of 1:23/12 (approximately 1:1.189), or 300 cents, 15.641 cents smaller.
