Cadd2

Anders told us how to play the Cadd2 chord once in a previous lesson. Can you tell me how to finger the chord again with the fret hand?

Anders mentions various ways to embellish the C major chord.  So, I'm sure exactly which one you are referring to.  Which course are you working on?

Here are links to 2 lessons I know of in which he mentions alternate voicings of the C chord.

You could also ask him directly in his forum.

Hope that helps!
