The Rockin' Open C
Now let me show you how to adapt your C chord to this rock tone, and as soon as you've learned that we'll use it in an example with the G and D chord as well. This is technically a Csus2 chord, but there's no point in getting too theoretical about it, because the players that "invented" it only cared about the sound of the chord, not the technical name.
