In music, the third factor of a chord is the note or pitch two scale degrees above the root or tonal center.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.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).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.
