This book offers a new and exciting way to learn guitar chords. It not only teaches people how to play chords, but how to play-by-ear in the process. In it you'll find chord charts organized by key and the Roman numeral numbering system, as well as chord formulas, how and why to use a capo and progressions to over 200 songs--along with their performance key. There are also worksheets that show how to build chord extensions and develop chord progressions using chord substitutions for each key, along with power chord and triad worksheets. There is something in this book for both the beginner and advanced player alike. This is a book about learning to play songs, not just chords.
