A chromatic tuner is a versatile tuning device that detects all 12 notes of the Western chromatic scale (C, C#, D, D#, E, F, F#, G, G#, A, A#, B). Unlike guitar-specific tuners that only recognize E-A-D-G-B-E, a chromatic tuner works for:
| String | Note | Frequency |
|---|---|---|
| 6 (Low E) | 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 (High E) | E4 | 329.63 Hz |
