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.

Fun Fact
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.
String Tension & Setup Tips
Recommended Gauge:Medium acoustic gauges (.013-.056). The low E drops two whole steps to C so a heavy 6th string is important; the high E drops to D. Most strings loosen relative to standard, so use enough mass to keep the low C defined.
