I want to say that this is for beginners because the tablature is easy to follow. That's what it means by easy guitar is the tabs, which is one note at a time. These are located on the bottom of each verse. Now, if you want the chords, they are listed on top of each verse. Yes, the chords are a little more difficult because you need to know the strumming methods used to get the right sound of the song, unless you are comfortable enough in your music playing to flex it a bit. No matter how you play you're not going to be able to get the exact sound of Taylor Swift's music without a full band.
The chords are listed above each verse and the fingers are clearly listed for the guitar player. You're not going to play with less than six chords per song and one song I know for a fact has ten chords. I learned how to play You Belong With Me using this book and that was my first real song using chords and not tabs. It takes six chords but has the easiest strumming pattern. You can find the strumming patterns at the beginning of the book and these are important unless you can play by ear, sometimes I can and sometimes I can't. The tabs are at the bottom of each verse and they tell you which fret you need your finger on and which string.
So, I'm definitely going to say this is easy guitar, but it's all about knowing what tabs is versus chords and which one is easiest for the person to play. When I first started to learn how to play I used tabs because it was easier to do it note by note instead of chord by chord. I'm very happy with my purchase.
