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 .
Septimal major third on C Play ⓘ A supermajor third is in between a major third and an augmented third, enharmonically equivalent to the minor fourth. An example of such an interval is the ratio 9:7, or 435.08 cents, the septimal major third (E). Another example is the ratio 50:39, or 430.14 cents (E ♯).
Just major third. Pythagorean major third, i.e. a ditone Comparison, in cents, of intervals at or near a major third Harmonic series, partials 1–5, numbered Play ⓘ.. In music theory, 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 ...
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. [2] The major second is the interval that occurs between the first and second degrees of a major scale, the tonic and the supertonic.
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 ...
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 ...
The third degree may be distant from the first by an interval of a major or minor third, but this does not make it the major or minor third degree: it is the third degree in all cases. (Or else one might have to call it the "second and a half" degree, etc.).
