Drop C Tuner Online

What Drop C tuning is

Drop C tuning is C G C F A D (low to high). It is built like Drop D but a whole step lower: first the entire guitar is tuned down a whole step to D standard, then the lowest string is dropped a further whole step to C. The result keeps Drop D's one-finger power-chord shape on the bottom three strings while sitting two semitones deeper, for a thick, aggressive low end.

Reading low to high: the sixth string is C, the fifth is G, the fourth is C, the third is F, the second is A, and the first is D. Notice that the bottom three strings spell C–G–C — a C power chord, the same shape relationship Drop D has on D–A–D. That is the whole idea: you get Drop D's riffing ergonomics, just pitched lower and chunkier.

Why and when to use it

Drop C exists for heavy, palm-muted riffing. The low C root gives the kind of deep, aggressive chug that defines modern metalcore and alternative metal, and the slack strings make heavy down-picking feel punchy and tight. Because the bottom three strings are a power chord, you can barre them flat at any fret and slide whole chords around with one finger — ideal for fast, syncopated riffs where you do not want to be reshaping chords mid-phrase.

Reach for Drop C when you want a heavier, lower sound than Drop D without going to a seven-string, when you are learning metalcore or nu-metal material, or when you want loose, low strings for chunky rhythm work. The looser tension also lends itself to wide bends and expressive lead lines over the low riffing.

String-by-string change from standard

To reach Drop C from standard EADGBE, every string comes down a whole step except the lowest, which comes down two whole steps. Derive each string: the low E drops two whole steps to C, the A drops a whole step to G, the D drops a whole step to C, the G drops a whole step to F, the B drops a whole step to A, and the high E drops a whole step to D. A useful check: your sixth string C should ring an octave below your fourth string C once both are set. Barring the bottom three strings at any fret then gives an instant power chord.

• Tears Don't Fall — Bullet for My Valentine
• Two Weeks — All That Remains
• Down with the Sickness — Disturbed
• My Curse — Killswitch Engage

These are cornerstones of metalcore, nu-metal and alternative metal — between them they show how Drop C underpins everything from melodic metalcore leads to crushing rhythm chug.

Common Genres

• Metalcore and post-hardcore
• Alternative metal and nu-metal
• Hard rock
• Djent-adjacent riffing

Practical tips and common mistakes

• Use heavier strings. Dropping this far slackens standard-gauge strings to a floppy feel; most Drop C players move to a heavier set (often .011–.054 or thicker) so the low C stays tight and intonates cleanly.
• Check the octave. The sixth-string C an octave below the fourth-string C is your built-in reference — if they beat against each other, the low string is off.
• Re-intonate if needed. A big drop like this can throw off intonation above the twelfth fret; a small saddle tweak often fixes sour high-fret chords.
• Approach from below. With five strings dropping a whole step and one dropping two, settle each by tightening up to the target so nothing slips flat under the looser tension.

How to use this tuner

• Click Start Tuner and allow microphone access when prompted.
• Pluck each string in turn — the matching peg below lights up automatically.
• Tap any peg to hear its exact target pitch as a reference.
• Lower every string a whole step and the low string two whole steps until each dial sits in the green band, then barre the bottom three strings to test the power-chord shape.
