What changes in Open C Minor
The open strings spell C minor with repeated roots and fifths plus E-flat as the minor third.
Make the tuning sound intentional
Create a slow pattern on the low C and G, then play a three-note melody ending on E-flat or C.
Shape tip: Use the high E-flat for melody and let the lower C and G strings sustain underneath.
Retune to C G C G C Eb safely
Several strings move far from standard; use suitable gauges and retune gradually.
Change one string at a time, approach the target pitch gradually and recheck every string after the neck settles. Stop if a string feels unusually tight, the bridge lifts or the instrument reacts unpredictably.
