Tune to an ensemble reference of A4 = 442 Hz
A4 = 442 Hz is a common higher reference for orchestras and ensembles. The difference from 440 Hz is small but audible enough that instruments will not agree if some players tune at 440 while others follow 442. Choosing the exact reference first makes the cents reading meaningful for every note that follows.
The tuner applies the selected A4 value to the full chromatic pitch set, rather than shifting only the A note. If your group asks for a nearby whole-hertz reference such as 441, 443 or 444 Hz, the same control supports every integer value from 415 to 450 Hz. Verify the agreed number before tuning the first note.
Four clear steps
How to tune accurately
- 1Open the live tuner from this page; the URL starts Chromatic mode at A = 442 Hz.
- 2Allow microphone access and play a clear sustained note from your instrument or ensemble reference.
- 3Check the header before tuning: it should show A = 442 Hz, not the default 440 Hz.
- 4Center the cents marker in the green ±5-cent zone for each note, then recheck after the instrument settles.
Selected reference
Pitch targets at A4 = 442 Hz
| Register | Target | Frequency |
|---|---|---|
| Lower octave | A3 | 221.00 Hz |

The selected reference rescales every chromatic target. Use the exact A4 value agreed by the ensemble before tuning any instrument.
Practical answers
Frequently asked questions
Why use 442 Hz instead of 440 Hz?
Some orchestras, ensembles and pianos use A4 = 442 Hz as their agreed reference. All players need the same reference pitch to match.
Can I tune to 441, 443 or 444 Hz?
Yes. The calibration control accepts each whole-hertz setting from A4 = 415 through 450 Hz, including 441, 443 and 444 Hz.
