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 .
The extremes of the meantone systems encountered in historical practice are the Pythagorean tuning, where the whole tone corresponds to 9:8, i.e. (3:2) 2 / 2 , the mean of the major third (3:2) 4 / 4 , and the fifth (3:2) is not tempered; and the 1 ⁄ 3-comma meantone, where the fifth is tempered to the extent that three ...

The fourth degree in major may be substituted for a seventh chord to create a "bluesy" sound. In a progression going up a fourth, if the first chord is a minor seventh chord, it can also be substituted for a seventh chord; a relative second degree can also be added before it to create a ii–V–I turnaround. (A sole minor seventh or seventh ...

In classical music, a third is a musical interval encompassing three staff positions (see Interval number for more details), and the major third (Play ⓘ) is a third spanning four half steps or two whole steps.

The harmonic major scale has its own set of modes, distinct from the harmonic minor, melodic minor, and major modes, depending on which note serves as the tonic.Below are the mode names, their degrees, and the following seventh chords that can be built using each modal tonic or degree of the parent mode as the root: a major seventh chord, a half-diminished seventh chord, a minor seventh chord ...
One variant of the supertonic seventh chord is the supertonic diminished seventh [3] with the raised supertonic, which equals the lowered third through enharmonic equivalence (in C: D ♯ =E ♭). The term supertonic may also refer to a relationship of musical keys. For example, relative to the key of C major, the key of D major (or D minor) is ...
In Classical music theory, a Neapolitan chord (or simply a "Neapolitan") is a major chord built on the lowered second scale degree. In Schenkerian analysis, it is known as a Phrygian II, [1] since in minor scales the chord is built on the notes of the corresponding Phrygian mode. The Neapolitan is found far more often in minor keys than in ...
