Drop C tuning is C G C F A D, from the lowest string to the highest. It keeps the same low-string relationship as Drop D, but brings every string down a whole step further. The result is a six-string guitar with a lower, tighter register for modern rock and metal while retaining familiar Drop-style power-chord shapes.

What is Drop C tuning?

Start with standard tuning, E A D G B E. Tune each string down two semitones to D G C F A D, then lower the sixth string another whole step to C. That gives you C G C F A D.

The three lowest strings are C, G, and C: root, fifth, octave. That is why a single barre across strings 6–4 makes a complete power-chord voicing at any fret.

How to tune to Drop C

  1. Tune down to D Standard: D G C F A D.
  2. Lower string 6 from D to C.
  3. Check the open low C against string 4 at the 12th fret: both are C, one octave apart.
  4. Retune after a few minutes of playing; lower tension can make fresh strings settle slowly.

Drop C is substantially lower than standard tuning. A heavier string set and a correctly adjusted setup help the low C stay defined and in tune, especially with aggressive picking.

Drop C power chords

The core Drop C shape is the same geometry as Drop D, only lower in pitch. Barre strings 6, 5, and 4 at one fret; mute the higher strings if you want a focused rhythm-guitar sound.

This makes pedal-tone riffs especially direct: leave the open C ringing or palm-muted, then move one-finger power chords above it. The low range gives even simple movements a dense, percussive weight.

Chords and shapes in Drop C

Because every string has moved, standard-tuning chord names no longer apply to the same fingerings. However, the intervals between strings 5–1 are unchanged from standard tuning, so movable shapes keep their internal logic; their sounding pitch is two semitones lower. The altered interval is between strings 6 and 5, so voicings that include the lowest string need to be relearned.

For full chords, either build voicings from strings 5–1 or treat the low C as a deliberate pedal tone. A C minor or C5 riff underneath upper voices often sounds clearer than forcing an open-position standard shape across all six strings.

Useful scales in Drop C

C Natural Minor

C natural minor is C, D, E♭, F, G, A♭, B♭. It starts at the open sixth string, making it a natural first map for the tuning. On the low C string: open C, fret 2 D, fret 3 E♭, fret 5 F, fret 7 G, fret 8 A♭, and fret 10 B♭.

C Phrygian

C Phrygian adds the tense flat 2 immediately above the open root: C, D♭, E♭, F, G, A♭, B♭. The first-fret D♭ against the open C is a classic low-tuned metal color. For a brighter third while keeping that flat 2, try C Phrygian Dominant: C, D♭, E, F, G, A♭, B♭.

Common Drop C progressions

i – ♭VII – ♭VI: C minor – B♭ – A♭. Play the roots as open, 10th, and 8th-fret power chords on strings 6–4.

i – ♭VI – ♭III – ♭VII: C minor – A♭ – E♭ – B♭. A broad minor-key movement that works well with an open-C pedal between chords.

i – ♭II: C5 – D♭5. The one-fret Phrygian clash is simple, immediate, and effective for breakdowns or tense riff openings.

Visualize Drop C on the fretboard

Select 6-String Drop C in AltTuningLab to recalculate every note across the 24-fret neck. Set the chord root to C and choose Power (5) to see the low-string barre, or overlay C minor and Phrygian to find lead lines around your riffs.

Songs to learn in Drop C

These songs use Drop C in different ways: tight palm-muted rhythm work, fast power-chord changes, melodic lead parts, and low-string pedal tones. They make useful references once you have the tuning under your fingers.

Learn the rhythm parts slowly with a metronome first. In lower tunings, clean muting and precise timing make as much difference as the notes.

Next steps

Once Drop C feels familiar, compare it with Drop D to hear how the lower overall register changes the same riff idea. If you want an additional low string without giving up the Drop relationship, move on to 7-string Drop A.
