Book excerpt: The Most Detailed & complete DADGAD Chord Book... DADGAD has become the most popular open tuning, yet until now there have been no extensive libraries of chord fingerings. The Big DADGAD Chord Book is thorough, readable, detailed and accurate, carefully mapping out the fingerboard like never before. It also has many valuable features to help songwriters, strummers and pickers find their way around: The whole fingerboard is shown for every chord, which helps you see and understand the geometry. The note names and scale degrees are shown for all chords, so you can clearly see the precise musical structure. Most chords have 5 or 6 strings sounding. Open and closed-position chord types are included."
