Having introduced 5 chord shapes for DADGAD tuning, let's turn our attention to open D (aka D A D F# A D).
As with DADGAD, drop the sixth string down a tone to D, then drop the first and second strings down a tone to D and A, respectively.
The final step is to drop the G string down a semitone to F#. The open D tuning is great for blues and fingerstyle acoustic pieces.
1. F#5
This powerchord shape features in Mumford And Sons’ The Cave, transposed to various fret positions.
2. Esus2
If we move the F#5 fingering down two frets and leave the third string ringing, this Esus2 is created.
3. Gadd9/D
This one is nice and easy, and sounds great when followed by a D chord played on the open strings.
4. Aadd11/D
This fingering uses the open strings as drones. Simply move the shape around the fretboard to find different sounds.
5. Amadd11/D
This final chord fingering is the minor version of the previous chord – it only differs by one note.
