Fiddle cross tuning: AEAE, ADAE, GDGD and Calico
Old-time fiddle cross tuning changes open strings to suit drones and particular tunes. Choose AEAE (Cross A), ADAE (High Bass), GDGD (Cross G), DDAD (Dead Man’s), GDAD or AEAC♯ (Calico), rather than assuming standard violin GDAE.

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
The charts run from the fourth string to the first. AEAE is A3 E4 A4 E5; ADAE is A3 D4 A4 E5; GDGD is G3 D4 G4 D5; DDAD is D3 D4 A4 D5; GDAD is G3 D4 A4 D5; Calico is A3 E4 A4 C♯5. DDAD lowers the fourth string to D3. Check your strings and setup before raising the lower strings for Cross A, and change tension gradually. Bow one string while damping its neighbors so the detector reads the intended drone.
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.
