C Standard Guitar Tuning
C Standard sets the six strings from low to high to C F Bb Eb G C. Its low, broad and authoritative voice works especially well for six-string metal, doom riffs and baritone-like range.

What changes in C Standard
All standard shapes remain intact but sound four semitones lower, placing the open sixth string on C.
Make the tuning sound intentional
Tune down in stages, confirm the low C with the reference and play a slow C5–Ab5–Bb5 riff.
Shape tip: Use C as a pedal tone under movable power chords and map your familiar E-minor patterns four frets lower in concert pitch.
Retune to C F Bb Eb G C safely
A heavy string set, careful intonation and often a longer scale length are recommended.
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.
Turn the open strings into music

Is C Standard Guitar Tuning safe for my guitar?
A heavy string set, careful intonation and often a longer scale length are recommended. Stop if a string feels unusually tight, the bridge moves or the guitar becomes difficult to intonate.
Can I use normal chord shapes in C Standard Guitar Tuning?
Some shapes may still work, but a low standard tuning changes at least part of the fretboard. Start with the open strings, simple drones and the shape guidance on this page.
Why do the strings go out of tune again after retuning?
Changing one string changes the total tension on the neck. Tune all six strings, wait briefly and repeat the process until every reference pitch remains stable.
