01
Prepare a clean test
Choose a quiet room and place the phone or computer close enough to receive a clear note without clipping. Fans, conversation, music and other ringing tone fields can all confuse a pitch detector.
Let the instrument settle at room temperature before comparing notes. Steel tension changes with temperature, so a handpan moved from a cold vehicle into a warm room may read differently for a while.
Use one note at a time
Dampen nearby fields if they continue to ring, then strike the field you want to check.
Use a consistent strike
Play gently and repeatably. A hard impact produces a strong transient that can briefly obscure the sustained pitch.
Wait for stability
Read the note only after the initial attack has passed and the tuner has confirmed several similar frames.
02
Compare several readings
Repeat the same note three or more times. Look for a similar detected note, frequency and cents direction across the cleanest strikes. A result that appears only once may be caused by noise, resonance from another field or microphone behavior.
Cents describe the pitch distance from the selected target. A negative value is flat and a positive value is sharp. The useful question is whether the reading is repeatable, not whether one frame briefly touches zero.
03
Know when a tuner is not enough
A handpan tone field contains a fundamental plus related octave and fifth resonances. A browser tuner usually follows the strongest periodic component it can isolate, which may not always be the fundamental.
If a note sounds unstable, beats strongly against nearby fields, or gives repeatable unexpected results after the instrument reaches room temperature, record your observations and consult an experienced handpan tuner. Avoid reshaping or hammering the shell yourself.
