Query: Poorly executed and misleading.

This book has a gimmicky title and a cheap price, but it fails deplorably on several fronts. For one, the lay-out and print quality are absolutely embarrassing considering the times we live in. One of the few musical examples actually looks as though it were rendered by a dot-matrix printer. Further, the unrealistic exercises are ambiguously described and seldom illustrated. They are also a complete waste of time since one is better off sightreading real compositions. That's why it's better to invest in sheet music/ etudes that suit one's tastes. The Musician's Institute Sightreading for Keyboard book is far more helpful and complete at a comparable price, offering several chapters of exercises and etudes without making ludicrous promises--very professional indeed. There is really no substitute for practice; forget the nonsense of "secrets" and invest elsewhere.
