The hard part was never the shapes — it's switching between them without the strum stopping. The trick is anchors: a finger that stays put, or slides a short trip instead of leaping. Pick one pair and drill it. Short trips, not jumps.
GBDGBGG→×CEGCEC Your 3rd finger is the anchor idea — G's low-string note and C's all sit close. Move as a unit; don't rebuild the hand from scratch.×CEGCEC→××DADF#D The whole hand shifts up a set of strings. Keep the shape's triangle and move it as one piece.GBDGBGG→EBEGBEEm Lift two fingers and you're most of the way to Em. Easiest switch in the kit — use it to keep momentum when a change feels scary.
Try this now Choose ONE pair below. Switch back and forth for a full minute, slow, keeping a steady down-strum going — even if the chord buzzes. Speed is a side effect of repetition, not effort.
