The small major seventh is a ratio of 9:5, [7] now identified as a just minor seventh. 35:18, or 1151.23 cents, is the ratio of the septimal semi-diminished octave. [8] The 15:8 just major seventh occurs arises in the extended C major scale between C & B and F & E. [9] Play F & E ⓘ
[citation needed] From that, we can list the scales and the triad qualities and the seventh chord qualities in each scale as degrees of Dorian mode and Aeolian dominant scale (Dorian ♯3 ♭6 scale) and Neapolitan major scale (Dorian ♭2 ♯7 scale) and double harmonic scale (Dorian ♭2 ♯3 ♭6 ♯7 scale) and the two types of Dorian ...

The pattern of whole and half steps characteristic of a major scale. The intervals from the tonic (keynote) in an upward direction to the second, to the third, to the sixth, and to the seventh scale degrees of a major scale are called major. [1] A major scale is a diatonic scale. The sequence of intervals between the notes of a major scale is:
A leading-tone chord is a triad built on the seventh scale degree in major and the raised seventh-scale-degree in minor. The quality of the leading-tone triad is diminished in both major and minor keys. [12] For example, in both C major and C minor, it is a B diminished triad (though it is usually written in first inversion, as described below).
For instance, in a chromatic scale each scale step represents a semitone interval, while a major scale is defined by the interval pattern W–W–H–W–W–W–H, where W stands for whole step (an interval spanning two semitones, e.g. from C to D), and H stands for half-step (e.g. from C to D ♭).
In music, a major seventh chord is a seventh chord in which the third is a major third above the root and the seventh is a major seventh above the root. The major seventh chord, sometimes also called a Delta chord, can be written as maj 7, M 7, Δ, ⑦, etc. The "7" does not have to be superscripted, but if it is, then any alterations, added ...
In music theory, the scale degree is the position of a particular note on a scale [1] relative to the tonic—the first and main note of the scale from which each octave is assumed to begin. Degrees are useful for indicating the size of intervals and chords and whether an interval is major or minor .
