Watch the Pivot Rotation online guitar lesson by Brad Carlton from Chord Studies: Flamenco Chords Vol. 3
In this progression we start by playing the G7b9#5(no b7) and use the third finger as a "pivot finger" allowing the entire form to rotate around this point as you play your second chord. This is another progression that calls for non contextual practice of the actual movement involved in order to really pull it off properly. Spend the time, focus on the arches of your fingers and getting the chords clean and the progression legato.
