Why it sounds like that

C 5th is built from the 1st and 5th degrees of the C major scale, giving the formula 1–5. The perfect fifth interval creates the open, neutral sound typical of power chords. Compare it with C major, which adds the major third E for a complete major triad.

What goes wrong with C 5th?

  • The 6th string sounds because the thumb does not mute it.
  • The 2nd string rings open when the fretting hand fails to mute it.
  • The 4th string buzzes because the middle finger is too far from the fret.

When to use it

C 5th functions as the tonic in C major progressions like C–F–G (I–IV–V) or C–G–Am–F (I–V–vi–IV). Its neutral fifth suits rock, punk, and metal rhythm parts. Use it with C major and G major for a full major sound.

Changing to and from C 5th

  • Sliding the shape down one fret to the 2nd fret gives B 5th.
  • Sliding the shape up one fret to the 4th fret gives C♯ 5th.

Which voicing to use

The 3rd fret position is the default and works well for barre chord progressions. The 8th fret position moves the shape up the neck for a higher voicing. The C5/G inversion puts the fifth in the bass, giving a less rooted, more open sound.

Common questions

What is the difference between C 5th and C major?

C 5th contains only C and G, while C major adds E. The missing third makes the power chord neutral and suitable for both major and minor contexts.

Can C 5th be played on the 6th string?

Yes, the 8th fret position uses the 6th string at fret 8 for the root C. The default position mutes the 6th string to keep the bass note on the 5th string.

Why is C 5th called a power chord?

Power chords contain only the root and fifth, producing a strong, focused sound with no major or minor quality. They are common in rock and metal because they sound clear under distortion.
