Open C-tuning

from Wikipedia, the free encyclopedia

The Open C tuning is a Scordatura the guitar . The strings of the instrument are tuned in such a way that a C major chord sounds when the open strings are struck.

The tuning

Starting from the normal tuning (E - A - d - g - h - e 1 ) you get the open C tuning (C - G - c - g - c 1  - e 1 ) as follows:

  • The sixth string (bass string) is tuned two whole tones lower to C.
  • The fifth string is tuned a whole tone lower to G.
  • The fourth string is tuned a whole tone lower on C.
  • The third string remains unchanged on g.
  • The second string is tuned a semitone higher on c 1 .
  • The first string remains unchanged on e 1

Fingering chart

By tapping all the strings with the help of a finger (full barre grip or T- handle) you get the other major chords of the chromatic scale - on the 1st fret C sharp major (D flat major), on the 2nd fret D major until you get reached C major again on the 12th fret.

The following is a fingering table of common chords, whereby further combinations result which are not shown here for reasons of space. The numbers indicate the frets of the strings to be picked, starting with the bass string. Strings marked with x are not struck.
