Standard four-string bass tuning
Standard bass tuning uses the same note names as the lowest four guitar strings but one octave lower: E1, A1, D2 and G2. Low notes need a clean attack and careful muting because their harmonics can be stronger than the fundamental.
Pitch leveling happens locally before detection to extend a useful sustain without replaying the microphone signal. Raw level information remains available for distinguishing a new pluck from a fading tail.
Four clear steps
How to tune accurately
- 1Select the low E1 string and pluck it cleanly while muting A, D and G.
- 2Let the note sustain; avoid repeated hard attacks while the marker is settling.
- 3Tune upward through A1, D2 and G2, holding each within ±5 cents for one second.
- 4Recheck E1 after all four strings are finished.
Reference: A4 = 440 Hz
Notes and frequencies
| Physical string | Target | Frequency |
|---|---|---|
| String 4 | E1 | 41.20 Hz |
| String 3 | A1 | 55.00 Hz |
| String 2 | D2 | 73.42 Hz |
| String 1 | G2 | 98.00 Hz |
Changing the tuner calibration recalculates every target from A4 = 415–450 Hz. The values above use the common 440 Hz reference.
Practical answers
Frequently asked questions
Why are bass notes harder for a phone microphone to detect?
Bass fundamentals are low and can be quieter than their harmonics. A clean single-string pluck, close placement and muting unused strings improve the reading.
Is bass EADG the same octave as guitar?
No. A four-string bass uses E1, A1, D2 and G2, one octave below the guitar's corresponding four lowest strings.
Does tuner.love upload my microphone audio?
No. Pitch analysis runs locally in your browser. Microphone audio is not uploaded to a backend and is never replayed through your speakers.
