As a beginner I have never had any real problems with the chords, but strumming completely eluded me. However very few, if any, books concentrate on strumming techniques.
This DVD starts at the very beginning and takes you through in sensible steps.
It assumes you don't know anything, but isn't in the least patronising or condescending.
If, like me, your right hand literally doesn't know what your left is doing, you should get this.
