Billie Jean opens with a deceptively simple four-chord figure — F#m, G#m, A, G#m — that immediately plants itself in the memory. The progression moves with a cool, coiled tension: the initial F#m settles into something slightly uneasy, the G#m lifts it with a half-step push, the A briefly opens things up before G#m pulls the phrase back, creating a satisfying circular pull that feels both restless and inevitable. That rocking motion between A and G#m gives the hook its characteristic itch, as though the harmony is perpetually on the verge of resolving but never quite commits. It rewards players instantly — there is weight and character in every change. A landmark of early eighties pop and R&B, the track exemplifies Michael Jackson's ability to marry rhythmic precision with deep melodic instinct.
