 | | Chords can be varied in many ways: you can add notes to an existing chord (e.g., the sixth), replace chord tones (e.g., use the fourth instead of the third), alter chord tones by flattening or raising them, and many combinations of the ones mentioned above. |
 | | In traditional harmony, these chords are thought of as tension chords, meaning they have to be resolved into their corresponding tonic chord (down a fifth). |
 | | It is regarded as part of the chord, not as an option (as, for example, are the ninth, eleventh and thirteenth). |
