How to tune a Cello

Notes

Step by step

1. Allow microphone access when your browser asks (audio stays on your device).
2. Play one note and let it ring. The tuner detects which string or note you are playing.
3. Follow the needle: left means flat (tighten / raise), right means sharp (loosen / lower).
4. When the note turns green you are within ±3 cents. Move on to the next one.

Pro tip

Bow long, even strokes near the fingerboard for the most stable reading.
