Tapping is a technique where the right hand taps a string and alternates with notes played by the left hand. A basic way you can start tapping is to find three notes that you want to play on one string and play them as triplets using this sequence: tap, pull-off, pull-off. The first note is tapped with your index or middle finger and then pulls-off onto a note held by one of the left hand fingers, which is then pulled-off onto another note held by a left hand finger. Other ways to tap are to use more right hand fingers, use open strings, and to use different rhythms.
Contrary to some other reviewers of this book, I like the book's set-up. New chords are given at the beginning at each stage only. There isn't a section that gives you chord diagrams so it forces you to memorize chord diagrams as you progress through the book rather than rely on convenient chord diagrams above every lyric. It isn't a chord reference book so if you're looking for that, there are plenty of cheap ones on Amazon or even free on the internet.
But than again, JamPlay does have a cool scale library tool (which is great for intermediate-advanced players), the production quality of JamPlay videos is generally higher (the educational value is about the same), and they release more new lessons and mini courses in different genres for intermediate-advanced guitarists, which might make them a better choice if you're an established player.
