I am only a very moderate piano player and found most of the pieces in this book too difficult for me. I've recorded some on a midi keyboard - which enables me to play each hand seperately then combine the two to hear what the piece should sound like.
Some of the compositions are pale imitations of the real thing -I would have preferred it if the composer had written something more original.
The practice pages give good advice, but you still need to have above-average dexterity to be able to maange them.
The biographical copy is interesting.
Overall, unless you are an above-average piano player, then you will find this book hard going.
