Theory overview
The notes in this tuning
form the c major triad, which is the basic C major chord. The notes of this
triad are (C, G, E). When you strum the strings with out holding down any
notes you will get a C major chord.
Open C tuning, just like
with all open tunings is very widely used by slide guitarists as chords can
be formed over a single fret. Open C tuning is used by musicians such
as John Butler (John Butler Trio) and Adrian Nation.
This form of guitar
tuning
provides a very full sound and is very good for acoustic instrumentals.
