The strengths of this method are the beautiful presentation, the fact already starting to play two hands, beautiful pieces that motivate to successfully play.
I have not been helped by a CD or a teacher. I followed through in the past against the rhythmic music lessons, and I acknowledge that it helped me a lot. The method would be more difficult to tackle for a true beginner.
Weaknesses: It is expected to have really almost as scores of lines to play, there is very little writing and explanations.
In short, this method is perfect and motivating for those who already have music theory basics.
