You can have a bit of fun with this riff. i've detailed it with double cords (eg. (567) (567)) as it sound better played as two quick cords rather than one. (345) (345) (345) (567) (567) (567) (456) (678) (678) (456)(567) (567) (345) (567)(567)(789)(789) (8910) (8910) (8910) (789) (789) (567) (567) (-456) (456)
