| | An Introduction To Chords |
 | | A major chord consists of a 'root' (the note on which the chord is based, usually also the lowest note of the chord), the note a 'major third' (four half-steps) higher than the root, and the note a 'minor third' (three half- steps) higher than the second note. |
 | | C9 means to take a C major chord and add the ninth tone of the C-major scale to it, so C9 would be composed of c, e, g, c, and d, in that order (though on guitar the d might be added an octave lower (the second) instead). |
 | | This "seventh chord as the dominant of a scale" is known as a "dominant seventh" or "major-minor seventh", and the term "seventh chord", if not modified somehow, almost always refers to this chord. |
