Easier ways to play it — 3 shapes, easiest first

A Shape Barre (2nd fret) Way 2 of 3
A Shape Barre (2nd fret)
intermediate
Barre at fret 2 — harder to hold than an open shape, but movable: slide it and you have every other seventh chord.
E Shape Barre (7th fret) Way 3 of 3
E Shape Barre (7th fret)
intermediate
Barre at fret 7 — the same movable idea, further up the neck: brighter, more compact, and easier to reach if you are already playing up there.
What beginners get wrong
Moving in and out of it
The shape above: Open Position — open position, so several strings ring unfretted.
Listening: each shape above has its own play button, and each one plays the notes that shape actually produces — not a generic triad.
