What do Robert Johnson, Beck, the Beatles, Pearl Jam, the Eagles, Led Zeppelin, Sonic Youth, Ry Cooder, and Ben Harper have in common? They have all at one time or another used open-tuned guitars to make their music. This book provides an introduction to the two most popular open tunings with over 300 chord shapes for open D and open G tuned guitar, useful tips on tuning and string set-up, music scores for four songs using open tuning chord shapes, a glossary of favorite chords and recommended listening. What a super book, this is such fun. I could use this for the next album. - David Bowie.
