(Strum It (Guitar)). The Strum It! series lets players strum the chords (and sing along) with their favorite hits. Each song has been selected because it can be played with regular open chords, barre chords, or other moveable chord types. Guitarists can simply play the rhythm, or play and sing along through the entire song. All songs are shown in their original keys complete with chords, strum patterns, melody and lyrics. This book includes 20 songs, including: All Shook Up * Great Balls of Fire * Lay Down Sally * Semi-Charmed Life * Surfin' U.S.A. * Twist and Shout * and more.
