Harpsichord tuner: pitch and temperament
Tune the harpsichord one note at a time, starting with the 8′ register. A 60-note FF–f‴ compass runs from F1 to F6, about 43.7–1397 Hz, within the chromatic detector’s approximate 25–2200 Hz range.
How to use it
- Choose the tuning, target or note convention described below. Set the reference A to match your ensemble before comparing pitches.
- Press Turn on microphone and allow microphone access. Work in a quiet place and sound one note at a time.
- Let the attack pass and compare a steady note, its octave and cents. Make a small adjustment, then repeat the measurement.
- Check the full instrument again after adjustments. Stop the microphone when you finish; reference tones and the guide remain available.
Help and explanations
Tuning and register
An A reference of 415 or 440 Hz sets the pitch level; it does not select a historical temperament. For Werckmeister III, Vallotti or quarter-comma meantone, follow your chosen temperament chart and its cents offsets instead of centering every note at equal temperament. Tune the 4′ register by octaves from the 8′: its top F7 is about 2794 Hz and exceeds this detector. Work with the stringing and pitch specified for the instrument.
Getting a steady reading
Place the microphone close enough to hear a clear tone, without touching the instrument. Stop reference playback before listening through the microphone. A room echo, another player or a strong overtone can make the detected octave jump. Repeat a short, steady sound and compare by ear before making another adjustment.
Tips
- Match the note letter and the octave, not only the needle position.
- Use the pitch and stringing intended for your model; a chart for another size can imply a different register.
- Return to the same reference A when playing with other musicians.
Frequently asked questions
Do I need to install an app?
No. The tuner works in a current browser with microphone permission. The audio is analyzed on your device and is not recorded or uploaded.
What does zero cents mean?
It means the measured pitch matches the selected reference. For a tradition with different intervals, use the intended cents offset and confirm the musical relationship by ear.
Why does the note or octave change?
The microphone can pick up an overtone or another sounding string. Isolate the note, reduce background sound and wait for a stable reading before changing the instrument.
