Drop C is one of the most common “heavy guitar” tunings because it gives you a low C for chunky riffs and easy power chords, while still feeling familiar under your fingers. In this guide you’ll learn the exact notes (C G C F A D), the easiest way to tune down without confusion, and how to use the TuneMode Drop C preset to lock in fast.

Key takeaways

  • The easiest path is Standard → Whole Step Down (D G C F A D) → Drop the low string to C.
  • Drop C power chords are simple: you can play many riffs with one-finger shapes on the lowest three strings.
  • If the low string feels floppy or buzzes, you may need heavier strings or a small setup tweak.
  • Use the preset so you always see the correct target notes: Drop C tuner

Who this is for

This is for you if:

  • a song says “tune to Drop C” and you want it done correctly in minutes
  • you’re writing heavier riffs but Drop D still feels too high
  • you tuned down and now your guitar feels buzzy or unstable

What is Drop C tuning?

Drop C is a 6‑string guitar tuning where the guitar is tuned down and the lowest string is “dropped” to make power chords easier.

From lowest (thickest) string to highest (thinnest), Drop C is:

C – G – C – F – A – D

For reference, standard tuning is:

E – A – D – G – B – E

If you like octave labels, Drop C is commonly written:

C2 – G2 – C3 – F3 – A3 – D4

(You don’t need to memorize the numbers — the note letters matter most.)


The easiest way to tune to Drop C (without getting lost)

You can tune straight from standard to Drop C, but it’s easy to overshoot because every string changes.

The simplest method is a two-step approach:

  1. Tune the whole guitar down one whole step to D Standard: D G C F A D
  2. Drop only the lowest string down to C: C G C F A D

This keeps you oriented: “everything down a step, then drop the low string one more step.”

Step 1: Open the Drop C preset in TuneMode

Open the preset so the tuner shows the target notes clearly:

Step 2: Tune to Whole Step Down (D G C F A D)

Starting from standard E A D G B E, tune each string down two semitones:

  • 6th string: E → D
  • 5th string: A → G
  • 4th string: D → C
  • 3rd string: G → F
  • 2nd string: B → A
  • 1st string: E → D

Go slowly. When you tune down, you’re loosening the string, so small peg movements can make bigger pitch changes than you expect.

Step 3: Drop the lowest string from D down to C

Now only change the lowest string:

  • 6th string: D → C

Once the tuner shows C and the cents are close to 0, you’re in Drop C.

Step 4: Re-check all strings once

Dropping the low string can slightly shift tension across the guitar. Do a quick pass again:

C G C F A D


Drop C vs C Standard (don’t mix these up)

These two get confused a lot:

  • Drop C: C G C F A D (the 5th and 4th strings are both C‑related for one‑finger power chords)
  • C Standard: C F Bb Eb G C (every string is tuned down evenly)

If your song says “Drop C,” it almost always means C G C F A D.


What Drop C changes (chords, riffs, and feel)

One-finger power chords (the reason Drop tunings exist)

On the lowest three strings (6–5–4), you can play a power chord with one finger:

  • Barre the same fret on strings 6–5–4
  • Examples (6–5–4):
    • Open (0) → C5
    • 3rd fret → D#5 / Eb5
    • 5th fret → F5
    • 7th fret → G5

This is why Drop C is riff-friendly: fast, tight shapes with minimal left-hand movement.

Familiar shapes still work (with one important warning)

Your top five strings are tuned like a “whole step down guitar,” so many shapes feel familiar. But the lowest string is different, so:

  • Standard open-chord shapes can sound wrong if you hit the 6th string by accident.
  • When in doubt, strum from the 5th string down for “normal chord” shapes.

Common Drop C problems (and how to fix them)

Problem 1: The low string feels floppy or buzzes

This is normal if you’re using light strings and tuning down.

Try:

  • A slightly heavier set (many players move up a gauge for Drop C)
  • A firmer picking hand (less “digging under” the string)
  • Raising the action a touch if the buzz is extreme

If you’re unsure, a quick setup from a tech can make Drop C feel dramatically better.

Problem 2: The tuner keeps jumping between notes

Drop tunings can produce big, boomy notes that confuse pitch detection.

Fixes:

  • Pluck one string at a time and mute the others.
  • Pick closer to the neck pickup (electric) for a stronger fundamental.
  • Tune with a clean tone (distortion adds harmonics).

If your tuner isn’t responding at all, use this checklist:

Problem 3: It sounds in tune open, but riffs sound off up the neck

That’s usually intonation. Tune the open string, then check the 12th fret:


A simple Drop C riff starter (no song required)

Here’s a basic “feel” exercise that uses the open low C and one-finger shapes. Palm-mute lightly and keep it tight.

  1. Chug the open 6th string (C) for a bar.
  2. Move to the 5th fret (F5) for a bar.
  3. Move to the 7th fret (G5) for a bar.
  4. Return to open (C5).

Once it feels good, set a tempo and practice clean transitions:


FAQs: Drop C tuning

Do I need heavier strings for Drop C?

Not strictly, but many players prefer heavier strings because the low string stays tighter, buzz is reduced, and tuning feels more stable.

Is Drop C the same as C Standard?

No. Drop C is C G C F A D. C Standard is C F Bb Eb G C.

Can I tune to Drop C from standard in one step?

Yes, but it’s easier to stay oriented if you go Standard → Whole Step Down → Drop the low string.

Will Drop C damage my guitar?

Tuning down reduces overall tension, so it’s usually safe. The main risk is setup-related: if you jump to much heavier strings, you may need a nut/action/intonation adjustment.

What’s the fastest way to get Drop C right?

Use a preset so the tuner always shows the target notes per string:


Next step: tune up and try it in context

Tune to Drop C, then test it with something musical:

  • Play open C5 (0–0–0 on the lowest three strings)
  • Practice moving that shape to the 5th and 7th frets with a click
