What is an Added Tone Chord?

An added tone chord is a type of chord that includes an extra note added to a basic triad without extending the chord into the full structure of a seventh or extended chord. The added note is usually taken from the scale related to the chord and is placed alongside the root, third, and fifth. For example, a Cadd9 chord contains the notes C, E, G, and D, where the D is the added tone.

Unlike extended chords such as ninth or eleventh chords, added tone chords do not include the seventh note of the scale. This keeps the chord sounding clear and stable while still adding extra color and richness. The added note can create a more open and interesting harmonic texture without making the chord overly complex.

Added tone chords are commonly used in many styles of music, including pop, rock, folk, and contemporary worship music. They are especially popular in guitar playing because they create bright and spacious sounds while remaining easy to play. Musicians use added tone chords to enhance chord progressions and give songs a more expressive and modern harmonic character.
