A drum groove opens alone, turntable scratching answering it. The signature guitar riff enters around 0:17, and bass and rhythm guitar complete the band near 0:22. The order of entries is the premise: beat first, riff second.

Run and D.M.C. enter rapping at 0:26. The intro groove continues without change; the formal event is entirely vocal — traded rap lines taking the foreground — with guitar licks beginning to answer phrase ends around 0:45.

The hook arrives sung just past 1:10 — She told me to walk this way, talk this way — pitched delivery where everything before was rapped. The _just gimme a kiss... like this_ tag lands at 1:30, and a brief riff-and-scratch reset follows it out.

After the reset, the second trading verse enters near 1:45, opening on School girl sleazy. It performs the same job as verse 1 — two voices passing lines over the unchanged riff — but now as confirmation rather than introduction, running its pre-chorus to when she told me how to walk this way around 2:32.

That last line tips into the sung hook again, and the guitar solo takes the foreground within the following half-minute. Near 2:54 the band thins to scratching and shouted ad-libs — the turntables answering the guitar the way the rappers answer the singer.

The riff returns at 3:00 and the sung hook follows near 3:06. From about 3:20 the form stops alternating and starts trading: riff-and-scratch groove, scatted vocals set against soloing guitar in the mid-3:40s, guitar-and-turntable exchanges, then shouted hook phrases with rapped interjections early in the 4:00s. Around 4:30 this settles into a steady outro jam, and near 4:47 the mix begins to fade while the jam keeps going, reaching silence only at the close — no final figure, just recession.

The whole form is one riff and one beat, handed back and forth between rap and rock until the fade ends the exchange.
