Watch the Close Voicings: online guitar lesson by Brad Carlton from Guitar Lab: The Golden Arp
This lesson completes the close voiced Add 9 chords with the three forms in 3rd inversion. The form that resides on the lowest four strings is a bit impractical, but the other two forms are quite useful. I'll discuss fingering options for the form that occurs on the top four strings. This lesson concludes with a review of all four inversions of the Add 9 chord in close voicings as played on the top four strings.
