Repeat this throughout the whole song and everytime you speed it up until the end, when you slow down again. After you repeat the Intro 4 times then the bass starts strumming:
C C C C E G E E E E C G
Then the bass starts to play something really weird and percussion starts up. Everything dies down at the end till you can hear just the Intro. Repeat Intro 3 times and end in a cymbal crashing.
