About A Augmented in Open D
The A Augmented chord contains the notes A, C#, F. In Open D tuning (strings: D–A–D–F#–A–D), the chord shapes differ from standard tuning because the open string pitches change. Open D tuning gives an open D major chord across all strings — ideal for slide guitar and Joni Mitchell-style playing. Diagrams above show all playable shapes in this tuning.
