Standard Tuning · E A D G B E
Tap Start and allow microphone access. Play one string at a time. The tuner automatically detects which string you are closest to and shows the deviation in cents. Adjust the tuning peg until the needle centers and the row turns green.
Standard tuning is the most common guitar tuning. The six strings, from thickest (lowest pitch) to thinnest (highest pitch), are tuned to these pitches:
| String | Note | Frequency |
|---|---|---|
| 6 (thickest) | E2 | 82.41 Hz |
| 5 | A2 | 110.00 Hz |
| 4 | D3 | 146.83 Hz |
| 3 | G3 | 196.00 Hz |
| 2 | B3 | 246.94 Hz |
| 1 (thinnest) | E4 | 329.63 Hz |
Always tune up to pitch rather than down — overshoot slightly and come back up so the string tension settles correctly. If your guitar is very out of tune, do a rough pass across all six strings first, then go back and fine-tune each one. Strings affect each other's tension, so a second pass usually gives better accuracy.
For the most stable results, tune in a quiet room and let each string ring for at least two seconds before reading the meter. Freshly changed strings need to stretch and will go flat quickly until they break in.
