The tuner is already set to Drop D: play each string and get it green. Below, which strings change from standard tuning and their frequencies.
Tap “Turn on microphone” and play a note.
Sound is analysed on your device. Nothing is recorded or sent anywhere.
The other strings stay as in standard tuning.
Only the 6th string drops a whole step, so the three low strings sit in fifths and octaves: power chords take a single finger. Common in rock, grunge and metal, and on classical guitar for pieces in D.
| String | Note | Frequency (A = 440 Hz) |
|---|---|---|
| 6 | D2 | 73.42 Hz |
| 5 | A2 | 110.00 Hz |
| 4 | D3 | 146.83 Hz |

From standard: String 6: E2 → D2, 2 semitones down. Use the tuner on this page, which is already set to the notes of Drop D.
Not for one or two semitones down. If you go lower, slightly heavier strings keep them from going slack and buzzing.
