The Piano Chord Collection

It was a nice surprise that exercises and songs were included. I haven't looked at the book much but if it mirrors the online charts, this is comprehensive blessing.
I took piano from a teacher who taught me the notes, the fingerings, and the notations but never the chords. It has been a life long dream to understand all the cords, not just the major ones.
Unbelievable low price, too! Win! Win! (and Win again!)

As a simple amateur of piano playing I find this chord compilation very helpful when reading it offline. I very much appreciate the work done by the author.
