Book excerpt: The word "DADGAD" refers to the names of the notes on the open strings of one of many alternate tunings for the guitar, one that is very popular with acoustic guitar players. It has a wonderfully warm resonance, allowing you to play simple single-note melodies, yet still fill out the sound of the instrument. The twenty Christmas carols presented here form a perfect introduction to playing guitar in DADGAD tuning. The melodies are presented without added bass notes or chords - just those great melodies, once heard, never forgotten. This means you already know what the tune is supposed to sound like, leaving you to concentrate on playing the notes on the right string and fret, and for the right length of time. This book is the easiest of Rob Mackillop's DADGAD books. It assumes you know how to hold and tune the guitar, and play some notes and a few simple chords. The book includes a "Technique Primer" to help get you up and running, plus the essential chord diagrams for playing in DADGAD tuning. Book includes access to online audio featuring Rob MacKillop's performance of each piece.
