Handpan tuner
Play one note and wait for a stable reading.

Strike one tone field to measure the fundamental, octave and compound fifth together. Targets use 1×, 2× and 3× the selected fundamental frequency.

Target deviations appear when a target note is available.
Lighter values marked “Last reading” retain a previous measurement when that resonance fades. Live values do not need to settle; saved results still require stability.
“Refining” uses a longer sound sample for faint resonances and may respond more slowly.
The compound fifth target is exactly 3× the fundamental, not an equal-tempered fifth. Missing resonances are not inferred.

Spread describes recent reading stability, not certified measurement accuracy.

HandpanTune measures the fundamental and any detected octave and compound-fifth resonances. Missing components stay blank. Stable readings do not guarantee accuracy. Consult an experienced handpan tuner for repairs or retuning.
How to get reliable readings
Set up your check
- Use a quiet room and keep your device close to the handpan.
- Choose the correct scale and A4 reference pitch. Select the target note when known to help identify its fundamental, then start the microphone.
- Play one note gently, without touching other fields, and wait for a stable reading.
Microphone processing varies by browser and device; requests to disable it may not take effect. Compare repeated strikes and, if needed, another input device.
Very close resonances can merge into one reading. If you hear beating (a pulsing sound), repeat the check and compare with a reference instrument.
Choose a checking mode
Single Note follows the detected pitch or compares it with a note you select.
Full Handpan Check walks through your scale one note at a time. Save each stable result, then review or copy the completed table.
