Watch the Pop: Technique 5 online guitar lesson by Robbie Calvo from RhythmCraft
Placing the capo at the second fret is going to let me play my first chord, the Emaj(add2) as a D shape, which is the (I) chord in our progression. A great way of finding the rest of the chords in the progression is by knowing the scale position of the chords in the first part. Once you've located the chord that is the (I) in the capo approach you should be able to identify the rest of the chords with relative ease.
It's very important to let you know that just because we are trying to play the chords from our original guitar part in another location doesn't mean that they have to be exact replicas, that would actually defeat the purpose of using the capo to give us subtle variations. For example the D chord doesn't contain the 2nd (9th) until I lift my second finger and when I play the D# note in this guitar part, I'm adding a major 7th sound to the chords regardless of whether it's in the first guitar part chord! It's these kind of variations that make this approach and technique so special. I hope that makes sense. If not, it will the more you try this and create two guitar parts for yourself.
