The table below summarizes the definitions of the diminished second in the main tuning systems. In the column labeled "Difference between semitones", m2 is the minor second (diatonic semitone), A1 is the augmented unison (chromatic semitone), and S 1, S 2, S 3, S 4 are semitones as defined in five-limit tuning#Size of intervals.
[augmented 1] The term is sometimes justified as a negative-numbered interval, [7] [8] and also in terms of violin double-stopping technique on analogy to parallel intervals found on other strings. [9] Some theoreticians make a distinction for this diminished form of the unison, stating it is only valid as a melodic interval, not a harmonic one.
Augmented seconds occur in many scales, most importantly the harmonic minor and its various modes. They also occur in the various Gypsy scales (which consist almost entirely of augmented and minor seconds). In harmonic minor scales, the augmented second occurs between the sixth and seventh scale degrees.
A major interval is one semitone larger than a minor interval. The words perfect, diminished, and augmented are also used to describe the quality of an interval.Only the intervals of a second, third, sixth, and seventh (and the compound intervals based on them) may be major or minor (or, rarely, diminished or augmented).
Not including the root motion, there is only a one-note difference between a half-diminished seventh chord and a V 7 chord with a flat ninth. Since it is built on the diatonic II chord of the minor scale, most of the time the II-V pattern resolves to a minor tonic (such as in the progression D ø 7 – G 7 ♭ 9 – Cm), but there are also ...
For this reason it is sometimes called a "diminished" scale, though in jazz theory this term is also applied to the octatonic scale. This interval is enharmonically equivalent to the augmented fourth found between scale degrees 1 and 4 in the Lydian mode and is also referred to as the tritone.
Augmented fourth between C and F ♯ and the diminished fifth between C and G ♭ are enharmonically equivalent intervals. Both are 600 cents wide in 12-TET. Since a chromatic scale is formed by 12 pitches (each a semitone apart from its neighbors), it contains 12 distinct tritones, each starting from a different pitch and spanning six semitones
French augmented sixth (Fr+ 6) modulation is achieved similarly but by respelling both notes of either the top or bottom major third (i.e. root and major third or diminished fifth and augmented sixth) enharmonically and inverting with the other major third (i.e. diminished fifth and augmented sixth becomes root and major third of the new Fr+6 ...
