Learning Chords Piano Chords Step-By-Step

I got my purchase recently and I must say that I am happy with it.
It is easy to ready and well written. The only tricky part is the material of the book, in other words it is like a file folder which it makes hard to keep it in good condition and also to move from page to page.
Despite all, I feel to recommend this book to anyone that wants to know more about chords but not really for beginners.

Worth getting it, lots of good info there.
