Major Third Tuning (C.E.G#.C.E.G#)

The major third tuning could be called the "Open C Augmented" tuning since it contains two octaves of a C augmented chord - two C's, two E's and two G#'s. Such multiple notes give a freedom to chord formation usually found only in open tunings. Whenever a chord is played at a particular fret on (say) the low C string, it can also be fretted at the same fret on the other C string. For example, an open E7 can be alternatively fingered in several ways...

Like all regular tunings, chords in the major third tuning can be moved across the fretboard (ascending or descending a major third for each string) as well as up and down the fretboard like a normal bar chord.
