Whole Step Down (D G C F A D)
Downtuned tunings lower all six strings by the same interval. Half-step down (Eb tuning) is popular among blues and classic rock players; it reduces string tension slightly and darkens the tone. Full-step down (D standard) is common in metal. The advantage of downtuned over drop tunings is that all your chord shapes remain the same; everything sounds lower.
