A capo is one of the simplest tools in a guitarist's kit — and one of the most useful. It lets you change the key of a song without relearning the chord shapes, making it easier to match a singer's vocal range or play along with a recording.
What Is a Capo?
A capo (short for capotasto, Italian for "head of neck") is a clamp that presses all six strings down at a specific fret. It acts like a movable nut, shortening the scale length and raising the pitch of all strings by the same amount.
How Does It Change the Key?
Each fret raises the pitch by one semitone. When you place a capo and play an open chord shape, the actual sound is higher. Try it below — drag the capo to any fret and watch the chord names update.

Common Uses for a Capo
- Matching a singer's key: If a vocalist sounds best in A but you only know G-shape chords, place the capo on the 2nd fret.
- Playing along with a recording: Many songs are recorded with a capo to give the guitar a brighter, higher sound.
- Avoiding barre chords: Instead of playing F major (a barre chord), put the capo on the 1st fret and play an open E shape.
- Tonal variety: Higher capo positions produce a jangly, banjo-like tone — perfect for folk and country.
How to Place a Capo
- Choose the fret where you want to place the capo.
- Clamp it just behind the fret (on the nut side), pressing all strings evenly.
- Strum all strings open to check for buzzing or muted notes — adjust if needed.
- Re-tune if necessary — capos can slightly pull strings sharp on some guitars.
