Drop C Tuning is a great asset for country, blues and metal players. It is very effective for playing powerful, deep guitar riffs that can’t be played in standard E tuning. If you have already viewed the lesson on standard D tuning, you will have a good idea of how drop C will work.
In standard D, each string is tuned down the same distance from standard E. Now to get drop C tuning, we just tune the low D string (what was orginally the E string) down further to C, or down a whole step.
With drop C tuning, you will have to adapt some chord shapes that use the low string, but this isn’t too difficult to understand.
