Bass tuning

Drop D (D-A-D-G)

Drop D on bass lowers the lowest string from E to D, giving D-A-D-G. You gain two semitones of low end and can play root fifths on the two lowest strings without shifting position.

The tuner opens already preconfigured; you only need to allow microphone access.

Strings and frequencies

How it sounds

It provides a deeper, heavier foundation, ideal for backing Drop D guitars or for punchy riffs. The change from standard is minimal, so it is quick to adapt to.

Styles and genres

Recommended string gauges

The fourth string feels a little loose dropped to D; a 0.050-0.110 set, or one with a reinforced E, keeps the low end defined. The rest is fine with normal gauges.

Tuning tip

If you are backing a guitar in Drop D, make sure you both start from the same reference D: just sound your low strings together and adjust until there are no beats.

Frequently asked questions

What notes is a bass in Drop D tuned to?

In Drop D the bass sits at D-A-D-G: you lower only the lowest string, from E to D (a whole step), and leave the other three exactly as in standard tuning. You gain two semitones of low end below the usual E.

Can you play Drop D on a 4-string bass?

Yes, and it is the normal case: most basses are four-string and classic Drop D is designed for them. You only drop the lowest string (E) to D; the other three are untouched.

How do you tune a bass to Drop D without a tuner?

By ear: fret the seventh fret of the fourth (lowest) string and lower it until it matches the open third string (A); when you release it, the open fourth gives the correct D an octave below. With this tuner you need none of that: it is chromatic, works with your phone's microphone and detects the low D directly.

Is Drop C lower than Drop D?

Yes. In Drop C the lowest string goes down to C, a whole step below the D of Drop D, so it sounds lower. On bass, Drop C is C-G-C-F (all four strings drop), whereas Drop D only lowers the lowest string to D.

Is Drop D easier to play?

For many riffs, yes: with the two lowest strings at D-A you can play fifths (power chords) with a single finger across the fret, no stretching. For melodic lines the fingering is the same as standard on three of the four strings, so it is quick to adapt to.

What can you play in Drop D that you can't in standard?

The gain is one-finger root fifths on the two low strings —great for fast, heavy riffs— plus two extra semitones of low end below E. Everything you played in standard still works; Drop D just adds that register and that convenience.
