You should be hearing the Single Shot rhythm section (bass/drums/vibes) providing a jam mix at the full speed of 90 bpm (beats per minute). Fetch your (tuned) instrument so you can play along ("reload" the page to restart the song if you have JavaScript, otherwise open the following link in a new window: PLAY).
Listen for the four-beat lead-in by the snare drum (giving you the tempo). Start one beat after the fouth snare-drum rim-shot. Follow along with the fretboard diagrams, guitar tablature and traditional sheet music, so you can add the guitar part youself to the rhythm section you should already be hearing.
