How to Tune a Guitar to Drop D
Drop D is standard tuning with the lowest string lowered one whole step: D A D G B E.
The quick method
- Tune the other five strings to standard: A D G B E.
- Play the open 4th string (D) as a reference.
- Lower the lowest string until it matches that D one octave below.
- Check the two D strings together for beating or shimmer.
Lumituner includes a Drop D preset, so the target note changes automatically while you tune. A settled strobe pattern means the string is centered; if it moves left or right, keep making small peg adjustments.
Open the tuner and choose Guitar → Drop D.
