Rock in B minor — syncopated muted strums
As already established on this grid's syncopated rhythm version, this combination stacks the Bm barre's repositioning at every loop repeat with the syncopation that complicates that repositioning — with muting added on top here, without changing the main diagnosis: the return to Bm still concentrates the difficulty.
Tips
First isolate the A→Bm transition under both the off-beat and muting, without the rest of the grid.
If this grid's syncopated rhythm version (unmuted) isn't reliable in a loop yet, work on it first.
On G, D and A, the palm does all the work with no barre constraint: consciously contrast that with Bm.
