Added Tone Chords

Added tone chords are triads with an
added note a second, fourth, sixth, ninth, eleventh, or thirteenth
above the chord root. For example, if we have a C-Major chord, with
the notes C, E, and G, and then add a D on top of the chord, we get a
Cadd9 chord. 









The following shows some more examples
of added tone chords.
