Title: On the Mark
Review: I don't know what the other reviewers are complaining about, the book is exactly what it's supposed to be, an in-depth investigation of the pentatonic scale. It doesn't claim to be an introduction to Jazz piano or Jazz improvization theory. I use it daily now and it sits on my shelf with other scale practice books from emile Decosmo and others. It's a perfect tool for the experienced pianist with all the transposition done for the player, all you have to do is sit down and start practicing. I have no complaints whatsoever.
