How to Tune to CGCGCD Tuning (Csus2 Modal)
A wide-open modal tuning (C-G-C-G-C-D) stacking fifths and fourths with a suspended 2nd on top. The three C octaves and reinforcing G notes give a huge, droning, harp-like resonance, while the high D adds tension and sparkle. Kaki King and folk guitarists like Nic Jones use its cavernous open sound for percussive, cascading fingerstyle.
Start in standard tuning (E-A-D-G-B-E) and change 5 of 6 strings:
| String | Standard | Target | What to do |
|---|---|---|---|
| String 6 | E2 | C2 | Tune down 4 semitones |
| String 5 | A2 | G2 | Tune down a whole step |
| String 4 | D3 | C3 | Tune down a whole step |
| String 3 | G3 | G3 | Leave as is |
| String 2 | B3 | C4 | Tune up a half step |
| String 1 | E4 | D4 | Tune down a whole step |
Because every open string is a C, G or D, almost any note you fret harmonizes with the ringing open strings. That is why modal tunings like this feel so forgiving and atmospheric — there are very few 'wrong' notes, which encourages the exploratory, ambient playing Kaki King is known for.
