Drop D Tuning

Drop D lowers only the 6th string a whole step, from E to D. Power chords on the bottom three strings become a one-finger shape, and the low D gives a heavier sound without retuning the rest of the guitar.

Sound is analysed on your device; nothing is recorded or uploaded.

About the Drop D Tuning

1 Press Start tuner and allow the microphone.
2 Pick your tuning, or keep Standard (E A D G B E).

Frequently asked questions

What are the notes of Drop D tuning?

From the 6th (thickest) string to the 1st: D A D G B E. From standard tuning: string 6 down whole step to D2.

What is Drop D tuning used for?

Rock, grunge, metal and folk fingerstyle.

Is my audio recorded or uploaded?

No. The tuner analyses the sound from your microphone in your browser, a few times a second, and throws it away. Nothing is recorded, saved or sent to a server.

Why does the tuner jump between notes?

Usually because more than one string is ringing, the room is noisy, or the note has faded. Mute the other strings with your fretting hand, pluck firmly, and read the needle while the note is still strong. Moving closer to the microphone helps on laptops.
