Getting Started
The Chromatic Tuner uses your device's microphone to detect pitch in real-time. It shows how sharp or flat you are from the nearest note.
- Click "Start Tuning" and allow microphone access
- Play a note on your instrument
- Watch the gauge - center means in tune!
- Adjust until the gauge is centered and green
- Use reference tones if you need to hear the target pitch

Tips & Tricks
Adjust A4 Reference
The tuner defaults to A4 = 440 Hz, but you can adjust this between 430-450 Hz to match orchestras or historical tunings.
Use Reference Tones
Play a reference tone to hear the target pitch. This helps train your ear and is useful for instruments without fixed pitch.
Reduce Background Noise
For best results, tune in a quiet environment. Background noise can interfere with pitch detection.
Let Notes Ring
Play a clear, sustained note for the most accurate reading. The tuner needs a moment to analyze the pitch.
Cents Explained
A cent is 1/100th of a semitone. Being within 5 cents of the target note is generally considered "in tune" for most purposes.
