A capo is a clamp that presses all the strings down at a specific fret. When you place a capo on the guitar neck, it acts like a movable nut.

This raises the pitch of the guitar while letting you keep using familiar chord shapes.

• Change the key of a song easily
• Use simple open chords in higher keys
• Match a singer’s vocal range
• Create a brighter or tighter tone
• Avoid difficult barre chords

Capos are extremely common in acoustic, pop, folk, and worship music.

Every fret you move the capo up raises the pitch by one semitone.

• Capo on 1st fret = +1 semitone
• Capo on 2nd fret = +2 semitones
• Capo on 5th fret = +5 semitones

The chord shapes stay the same — only the key changes.

If you play a G chord shape:

• No capo → sounds as G
• Capo 2nd fret → sounds as A
• Capo 3rd fret → sounds as B♭

This works for all open chord shapes.

1. Place the capo just behind the fret (not on top of it)
2. Make sure it presses all strings evenly
3. Check that no strings are buzzing
4. Re-tune slightly if needed

• Placing the capo too far from the fret
• Not clamping firmly enough
• Forgetting to re-check tuning
• Assuming chord names stay the same

Capos and barre chords both allow you to play in different keys. The difference is how much effort and control they require.

• Capo: easier, lighter pressure, open-chord sound
• Barre chords: more control, movable anywhere, stronger technique
