Mandocello tuner: C2 G2 D3 A3
The mandocello is tuned C2 G2 D3 A3, one octave below the mandola and like the cello’s open strings. Its four courses normally contain two strings each in unison, so the page shows eight strings grouped into four targets.

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
Read from the fourth, lowest course to the first. Mute one member of a course while plucking its partner, then check the second string and listen for beating between them. The low C2 is about 65.41 Hz: if an overtone produces C3, compare the octave rather than tightening the bass string. Use the mandocello’s own scale and string gauges. A mandola CGDA chart has the same letters but is an octave higher, and would apply too much tension if copied literally here.
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.
