dropD

Drop D is an alternate guitar tuning in which the low E string is tuned down a whole step from E2 to D2, while the remaining strings stay in standard tuning (E A D G B E). This lowers the overall pitch and gives the instrument a heavier, deeper low end without changing most of the familiar chord shapes.

The tuning is particularly popular for riff-based styles because it enables easy power chords and droning patterns across the lower strings. With the low D string, many riffs can be played with simple shapes, and the open D and A strings can ring together to create a thick, resonant sound. Tuning can be done with a guitar tuner or by matching the lowered string to a reference pitch, and it is commonly used across electric and acoustic guitars.

Drop D is part of a broader family of drop tunings in which the lowest string is lowered to enable different sonic textures. Variants include Drop C and Double Drop D, the latter lowering both the sixth and fourth strings to D. While it simplifies certain riffing approaches, it also changes string tension and feel, which may influence tone and neck relief. Players may adjust gauge and setup accordingly to maintain playability and intonation.
