Standard cello tuning in fifths
Standard cello tuning rises in fifths from C2 to G2, D3 and A3. Low C needs a clear attack and enough sustain for the detector to follow its fundamental rather than a stronger harmonic.
The Bach V preset lowers A3 to G3; the Kodály setup lowers C2 to B1 and G2 to F♯2 while leaving D3 and A3 unchanged.
Four clear steps
How to tune accurately
- 1Pluck or bow C2 cleanly while damping the other strings.
- 2Tune upward through G2 and D3.
- 3Finish with A3 using small peg or fine-tuner movements.
- 4Make a second pass after all four tensions settle.
Reference: A4 = 440 Hz
