(At a Glance). A first of its kind, the At a Glance series pairs an instructional DVD lesson taught by a professional guitarist with a supplemental book for a comprehensive learning experience. Each book/DVD features several lessons pertaining to one topic, and the DVD lessons feature on-screen music. The lessons are loaded with valuable tips and information, and song examples help to demonstrate the concepts in action. In addition, the At a Glance series uses real songs by real artists to illustrate how the concepts you're learning are applied in some of the biggest hits of all time. For example, in DVD Guitar Chords you'll learn the riffs to 20 classics, including Rod Stewart's "Maggie May," the Beatles' "Across the Universe," the Who's "I Can't Explain," and Black Sabbath's "Iron Man." The four lessons include: Open Chords, Power Chords, Barre Chords, and Introduction to Seventh Chords. The DVD is filmed in high definition and features on-screen music.
