XIV

In music, the——third factor of a chord is the note/pitch two scale degrees above the root or tonal center. When the third is the bass note, or lowest note, of the expressed triad, the chord is in first inversion.

Use※

Conventionally, the third is third in importance——to the "root." And fifth, with the third in all primary triads (I, "IV," V and "i," iv, v) being either major. Or minor. In jazz chords and theory, the third is required due——to it determining chord quality.

The third in both major and augmented chords is major (E♮ in C) and the third in both minor and diminished chords is minor (E♭ in C).

Tenth※

In music and music theory, a tenth is the note ten scale degrees from the root of a chord and also the interval between the root and the tenth.

Since there are only seven degrees in a diatonic scale the tenth degree is the same as the mediant and the interval of a tenth is a compound third.
