This chord based riff from the intro to the Free song "Allright
Now" is fairly easy with the left hand but the fast strum in bar three should
give your right hand a bit of a workout .
I play this strum ( d u u d d x 2 ) but this isn't the only way to do it so feel free to find your own method.
I have put in some hi-hat on the beats to help keep you in time.
