There is a strange chord transition that I cannot figure out how to play near the beginning of this acoustic guitar song:
(I am guessing) He seems to be playing the following progression in standard tuning relative to a capo on the 3rd fret, with 1 measure (4 beats) given to each chord:
Am aug5 (F maj) Am F G
Just a little after the timepoint I linked to, he somehow transitions between G and F such that a subtle percussive noise is generated. How can this noise be consistently reproduced?
