Advanced players stay away, but this is as good a beginning guitar book to learn to play and strum that there is. The chords are simple, so spending time with this book will really teach you to comfortably play G and C chord songs.
Many of the songs are "dumbed down" or have had the key moved. Purists will be unhappy, as the songs lose a lot of that Bob Dylan funk, but, nonetheless, virtually every song in the book sounds good when played and is recognizable. Plus, for beginners, almost every song can be played with either a Carter-Style strum or a simple 1 2 3+ 4+ strum pattern.
Within weeks, you'll be able to play Dylan songs recognizably and, if you have even been playing for 6 months, you'll be able to play many of these songs on the first run-through.
