G 5th chord on guitar (G5)

Why it sounds like that

G 5th is built from the 1st and 5th degrees of the G major scale, giving the formula 1–5. The perfect fifth interval produces the hollow, neutral sound of a power chord. Compare it with G major, which adds the major third B for a complete major triad.

What goes wrong with G 5th?

• The 3rd string sounds because the fretting hand fails to mute it.
• The 2nd string rings open when the fretting hand fails to mute it.
• The 5th string buzzes because the middle finger is too far from the fret.

When to use it

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

Changing to and from G 5th

• Sliding the shape down one fret to the 2nd fret gives F♯ 5th.
• Sliding the shape up one fret to the 4th fret gives A♭ 5th.

Which voicing to use

The 3rd fret position is the default and works well for barre chord progressions. The 10th fret position moves the shape up the neck for a higher voicing. The G5/D inversion puts the fifth in the bass, giving a less rooted, more open sound.
