DADGAD is a magical guitar tuning that engenders clear, ringing sounds and haunting voicings. Al Petteway, a master of the form, teaches this tuning for playing Southern Mountain songs and instrumentals: John Henry · Sitting on Top of the World · I Am a Pilgrim · Wondrous Love · Wayfaring Stranger · Shady Grove · Pretty Polly · and Craggy Pinnacle, the Celtic-inspired tune he wrote for Ken Burns' National Parks PBS series.
