About the C5 Chord
The C5 power chord is rock music's most fundamental sound—raw, powerful, and deliberately ambiguous. Built from just C and G (the root and fifth), this two-note chord intentionally omits the third, creating a sound that's neither major nor minor. This ambiguity gives power chords their versatility and edge.
What makes C5 special is what it lacks. Without the third, C5 can work in any context—major, minor, or modal. This flexibility made power chords the backbone of rock, punk, and metal. When guitarists crank up the distortion, the clean simplicity of root-fifth cuts through perfectly.
On piano, C5 is simply C and G—perhaps the simplest possible chord. Yet this simplicity has driven countless songs. Power chords prove that musical power doesn't require complexity.
Music Theory & Usage
C5 functions wherever C major or C minor would work—its ambiguity allows both. In rock, power chords often move in parallel motion, creating progressions that would sound crude with full triads but powerful with fifths only.
The chord appears throughout rock, punk, metal, and any genre where raw power matters more than harmonic complexity. Power chords also appear in orchestral writing as "open fifths."

Frequently Asked Questions about C5
What notes are in C5?
C5 contains only C (root) and G (perfect 5th). There is no third, which is why it's neither major nor minor—it's ambiguous by design.
Why are power chords used in rock?
Power chords lack the third that would make them major or minor. This simplicity works perfectly with distortion (which makes complex chords muddy) and creates a raw, powerful sound that defines rock.
Is C5 the same as C(no3)?
Yes, C5 and C(no3) mean the same thing—a C chord without the third. "Power chord" and "5 chord" are informal names; "no3" is more technical notation.
Can I use C5 instead of C major or C minor?
Yes—power chords work in both major and minor contexts because they're ambiguous. This is their strength: C5 fits wherever C fits, without committing to a mood.
