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:
X|X|5|3|0|5
X|X|5|2|0|5
X|X|3|2|0|4
X|X|2|3|3|1
or:
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?
