The arrangements in this book are really great. I am an intermediate player, and I am able to sight read these songs with just a few errors. With a few run-throughs, I should be quite competent. But even though the arrangements are simple, just the right chords have been selected, that still produce a nice overall song. I don't know how to explain it better, but I'm sure most players have purchased some sheet music and then when the time came to play it, it just never sounded great, even if you were playing it exactly as written. Maybe the arranger decided to get fancy on a few chords (to the point where you do a double check and make sure you didn't miss a note, and then wonder whether or not it might be a typo), or maybe they simplified it too much. This book is the complete opposite- it has just the notes you need to capture the essence of each song, and nothing you don't. I have more use for some sections of the book than others (I have a 2 year old, so I'm already getting pretty good at the children's songs, and I anticipate the patriotic and holiday songs will also be in heavy rotation), but they have made some nice, general selections that will appeal to a wide audience. If you have a crowd who wants to gather around the piano and sing, you will get pretty far with this one book. I would recommend this for any piano library.
