What to watch for
At least one shape here is a full barre — one finger pressing all six strings, no open strings to lean on. Fret it unplugged first; if a string buzzes, it's the barre, not the chord. Listen for the 7th in these chords — it's the note doing most of the harmonic pull, and it's the first thing that disappears if you fret only the plain triad underneath it.
