Super method for small pianists

I use this method with my three children who are 5 and 7 years, and the least we can say is that it is effective and fun.
The children quickly used their hands. They love all the songs, they break out to play in a loop every day (yes, you have here a bit of patience ...).
As a bonus, the concepts of music theory have gradually learned and "painless".
The method is easy to use, even for a parent who knows nothing about music because everything is explained. So well explained that children do not hesitate to put all alone at the piano with their high color method.
In short, I think this method is a very good introduction to the piano to young children.

Note: to complete the method, I try in parallel to help my children to read notes, using quite simply a music book and crayons.
