About Drop D tuning

Drop D on bass mirrors the guitar version: the lowest string drops a whole step to D while the rest stay put. If the guitarists are in Drop D, this keeps you locked to their low root — and it adds a useful low D for walking lines and heavier grooves.

Tune the E string down until the needle centers on D1 (36.7 Hz). The 12th-fret harmonic reads faster than the open string at these depths.

How to tune to Drop D from standard

  1. String 4 (E1): tune down a whole step to D1.

After changing string tension this much, make a second tuning pass — the neck settles slightly and the first strings you tuned will have drifted.

String gauge advice

Standard sets cope; a .110 low string tightens the dropped D.
