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.
Practice at the right tempo
This song sits at 105 BPM. Start at 60% until the changes are clean — speed is a by-product of accuracy, not a goal.

Play it on a live fretboard
Every shape, every voicing, and the scale that fits over them — on a board you can hear. Then just talk to it: Melody Monkey's personal music teacher controls the fretboard, so ask for a chord, a scale, a progression, or why any of it works, and watch it land under your fingers. Free to start.
