How to use the vocal tuner
- Click Start Tuning and allow the microphone. Keep background noise and music off.
- Sing a long, steady vowel such as "ah" at a comfortable volume. Vibrato makes the meter wobble, so use a straight tone while checking pitch.
- Green means you are within the in-tune window. Left means flat (sing higher), right means sharp (sing lower).
Find your voice type
Sing from your lowest comfortable note to your highest and write down the notes shown. Typical ranges for each voice type:
| Voice type | Typical range |
|---|---|
| Soprano | C4 (262 Hz) – C6 (1047 Hz) |
| Mezzo-soprano | A3 (220 Hz) – A5 (880 Hz) |
| Alto / Contralto | F3 (175 Hz) – F5 (698 Hz) |
| Tenor | C3 (131 Hz) – C5 (523 Hz) |
| Baritone | A2 (110 Hz) – A4 (440 Hz) |
| Bass | E2 (82 Hz) – E4 (330 Hz) |
These are typical ranges — trained singers often exceed them, and a comfortable range matters more than the extremes.
Practice ideas
- Play a reference note with the pitch pipe, then match it with your voice. → Open the pitch pipe
- Sing a scale slowly and make sure each note turns green before moving on.
- Watch held notes at the end of phrases — that is where most singers drift flat.
