Open C tuning for guitar (C-G-C-G-C-E) creates a wide, orchestral C major chord across the open strings. The low C gives the guitar a piano-like foundation, while the high E keeps the tuning bright and major.
Use this Open C tuning online page as a CGCGCE note check: 6th string C2, 5th string G2, 4th string C3, 3rd string G3, 2nd string C4, and 1st string E4.
This tuning is popular with acoustic players, fingerstyle guitarists, and songwriters who want huge open-string resonance. It works especially well for slow arpeggios, droning bass notes, and arrangements where the guitar needs to sound bigger than standard tuning.
Open C changes the feel of the fretboard more dramatically than Open D or Open G. Because several strings move far from standard pitch, tune slowly and recheck each string after the neck settles.
Open C is also written as CGCGCE tuning because the strings run C-G-C-G-C-E from lowest to highest. It is not the same as C standard tuning, which keeps standard intervals at C-F-Bb-Eb-G-C instead of forming an open C major chord.
