A minor third is the smaller of two commonly occurring musical intervals compounded of two steps of the diatonic scale. The prefix 'minor' identifies it as being the smaller of the two (by one semitone); its larger counterpart being a major third. The minor third is abbreviated as m3 and its inversion is the major sixth. In music theory, the word inversion has several meanings. ... The musical interval of a major sixth is the relationship between the first note (the root or tonic) and the sixth note in a Major scale. ... A semitone (also known in the USA as a half step) is a musical interval. ... In music, specifically, musical set theory an interval class, or unordered pitch-class interval, is an interval measured by the distance between its two pitch classes ordered so they are as close as possible. ... In music, just intonation, also called rational intonation, is any musical tuning in which the frequencies of notes are related by ratios of whole numbers. ... The cent is a logarithmic unit of measure used for musical intervals. ... An equal temperament is a musical temperament â€” that is, a system of tuning intended to approximate some form of just intonation â€” in which an interval, usually the octave, is divided into a series of equal steps (equal frequency ratios). ... In music, just intonation, also called rational intonation, is any musical tuning in which the frequencies of notes are related by ratios of whole numbers. ... In music theory, the term interval describes the difference in pitch between two notes. ... In music theory, a diatonic scale (from the Greek diatonikos, to stretch out; also known as the heptatonia prima; set form 7-35) is a seven-note musical scale comprising five whole-tone and two half-tone steps, in which the half tones are maximally separated. ... A major third is the larger of two commonly occuring musical intervals that span three diatonic scale degrees. ... In music theory, the word inversion has several meanings. ... The musical interval of a major sixth is the relationship between the first note (the root or tonic) and the sixth note in a Major scale. ...

The minor scale is so named because of the presence of this interval between its tonic and mediant (1st and 3rd) scale degrees. Minor chords too, take their name from the presence of this interval built on the chord's root (provided that the interval of a perfect fifth from the root is also present or implied). A minor scale in musical theory is a diatonic scale whose third scale degree is an interval of a minor third above the tonic. ... The tonic is the first note of a musical scale, and in the tonal method of music composition it is extremely important. ... For mediant in mathematics, see Mediant (mathematics) In music, the mediant is the third degree of the diatonic scale. ... In music or music theory a scale degree is an individual note of a scale, both its pitch and its diatonic function. ... Generally speaking, a minor chord is any chord which has a minor third above its root, as opposed to a major chord which has a major third. ... In music the root (basse fondamentale) of a chord is the note or pitch upon which that chord is perceived or labelled as being built or hierarchically centered upon. ... The perfect fifth or diapente is one of three musical intervals that span five diatonic scale degrees; the others being the diminished fifth, which is one semitone smaller, and the augmented fifth, which is one semitone larger. ...

A minor third in just intonation corresponds to a pitch ratio of 6:5. 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. In other meantone tunings it is larger, and in 19 equal temperament it is very nearly the 6:5 ratio of just intonation. In music, just intonation, also called rational intonation, is any musical tuning in which the frequencies of notes are related by ratios of whole numbers. ... Equal temperament is a scheme of musical tuning in which the octave is divided into a series of equal steps (equal frequency ratios). ... A semitone (also known in the USA as a half step) is a musical interval. ... The cent is a logarithmic unit of measure used for musical intervals. ... Meantone temperament is a system of musical tuning. ... In music, 19 equal temperament, called 19-tet, 19-edo, or 19-et, is the scale derived by dividing the octave into 19 equally large steps. ...

Other pitch ratios are given related names, the septimal minor third with ratio 7:6 and the tridecimal minor third with ratio 13:11 in particular. In music, the septimal minor third, also called the subminor third (by eg Helmholtz) is the musical interval exactly or approximately equal to a 7/6 ratio of frequencies. ...

The minor third is classed as an imperfect consonance and is considered one of the most consonant intervals after the unison, octave, perfect fifth, and perfect fourth. In music, a consonance (Latin consonare, sounding together) is a harmony, chord, or interval considered stable, as opposed to a dissonance, which is considered unstable. ...

The perfect fifth or diapente is one of three musical intervals that span five diatonic scale degrees; the others being the diminished fifth, which is one semitone smaller, and the augmented fifth, which is one semitone larger. ... The perfect fourth or diatessaron, abbreviated P4, is one of two musical intervals that span four diatonic scale degrees; the other being the augmented fourth, which is one semitone larger. ...

Instruments in A are a minor 3rd lower than the written pitch in the concert pitch, i.e. how they are heard. Therefore, to get the written pitch, transpose the concert pitch up a minor 3rd.

 Online Encyclopedia and Dictionary - Minor third (154 words) 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. A minor third in just intonation most often corresponds to a pitch ratio of 6:5 (or 1:1.2), or various other ratios. The minor third is considered the most consonant interval after the unison, octave, perfect fifth, perfect fourth, major third, and minor sixth.
 Minor third - Wikipedia, the free encyclopedia (365 words) The minor third is abbreviated as m3 and its inversion is the major sixth. Minor chords too, take their name from the presence of this interval built on the chord's root (provided that the interval of a perfect fifth from the root is also present or implied). The minor third is classed as an imperfect consonance and is considered the most consonant interval after the unison, octave, perfect fifth, perfect fourth, major third, and minor sixth.
