DADGAD tuning is a popular alternative tuning that offers a rich and exotic sound.This distinctive arrangement creates a droning and open sound, with rich harmonies and resonant chords. DADGAD tuning is particularly favored by folk, Celtic, and world music guitarists, as it allows for unique chord voicings and melodic possibilities. The lower four strings are exactly the same as drop-D tuning, and the top two are simply lowered by a whole step. This makes it a great first step into the world of alternate tunings.
