Watch the Cabriolet online guitar lesson by Robbie Calvo from The Rhythm Architect
This is a very melodic chord progression and great to just jam over and over. I wanted to also give you guys an A section and a B section to learn to add some variation. It may inspire you and give you an idea into how you actually transition into new sections with the same key.
The chords aren't easy for this progression but they are worth learning if you don't know some of them. The five fret fingerings of the Aadd9 and Badd9/4 are classic chords that have been used by the Police, Led Zep etc., and can be used in any style of music.
The B section chords are all diatonic to the key of E but I've opened them up a little bit by adding in the open strings in some cases.
