I hadn't played the piano for about 20 years until I bought this book. I love it. I had a huge grin when I first played The Throne Room, especially The Force theme.
It certainly is easy piano; I could sight read fairly comfortably for the most part, with easy key signatures and rarely more than three fingers used in the bass (which is evenly spread between one, two and three notes at any one time) and mostly single notes in the treble. Being Star Wars, it is easy to recognise a wrong note - these tunes are so familiar.
However, you need to beware. Amazon has posted the same reviews for this book and the one with the same cover - the paperback version. Amazon has also included both song lists in the Editorial Reviews. These two seemingly identical books have a few differences in what songs they include:
1) Cantina Band (Star Wars) and Ewok Celebration (Return of the Jedi) are only in Easy Piano.
2) Ben's Death/Tie Fighter Attack (Star Wars), Han Solo and the Princess (the love theme from Empire), May the Force Be with You (all movies), Parade of the Ewoks (Return of the Jedi), Jedi Rocks (the replacement song for the Max Rebo Band in the Return of the Jedi Special Edition), and Yoda's Theme (Empire) are only in the Paperback version.
So you need to be careful that you buy the one you really want. They are both easy piano. You also need to be mindful that this edition is strictly for piano.
Overall, this product is fantastic. Even the learner can master the tunes within months. If you are adept at the piano, look for one of the more difficult versions.
