Rock in E minor (basic version) — syncopated rhythm
The syncopated version of the basic strumming pattern, applied to a grid that changes chord every bar — an important technical difference from the syncopation already worked on the blues grid, where the chord stays held for several bars. Here, the off-beat accent has to land just before or just after a chord change depending on where it falls in the bar, which forces the left hand to anticipate the change slightly earlier than in the non-syncopated version: it no longer has all the dead time of the regular pattern to reposition.
Tips
First work out, chord by chord, whether the change falls just before or just after the off-beat accent: it isn't consistent, and playing without knowing leads to late changes.
Slow this pattern down noticeably more than usual: the combination of chord-change-plus-syncopation is more demanding than either difficulty on its own.
Once the grid is stable, compare it with the non-syncopated version already worked on: it's the best way to hear exactly what the syncopation changes about the overall feel.
