What does a guitar capo do?

A capo clamps across all six strings at a specific fret, raising the pitch of all open strings simultaneously. This allows you to use the same open chord shapes you already know but produce those chords in a higher key. For example, with a capo on fret 2, a C chord shape produces a D chord sound.

Where should I place a guitar capo?

Place the capo immediately behind (just to the left of) the fret, as close to the fret as possible — exactly as you would place a left-hand finger. If it is too far back from the fret, strings may buzz. Press it firmly enough that all strings ring clearly. Always check tuning after fitting.

How do I know which capo position to use?

To find the right capo position for a singer: ask them to hum the melody or find a comfortable starting note. Find that note on the guitar and place the capo at the fret that puts your familiar open chord shapes in that key. The chord position chart in this lesson gives you the chord name equivalents at each position.

Do I need to retune my guitar after using a capo?

Yes — always retune after fitting a capo. The extra pressure of the capo bar can push some strings slightly sharp. Play each string and check with a tuner or by ear. Elastic capos in particular need careful tension adjustment to avoid over-sharpening.

Should a capo replace learning barre chords?

No — a capo is a useful tool but not a replacement for barre chords. A capo can only move all strings up simultaneously, while barre chords give you flexibility to play any chord at any position. Learn both: use the capo for transposing when it suits, and use barre chords when you need individual chord position control.

How to Use a Guitar Capo — Types, Positions & Chord Changes

What a Capo Does

A capo ('short for 'capotasto' — Italian for 'head of neck') is a device that clamps across all six strings at a chosen fret, raising the pitch of every open string simultaneously. It acts like a moveable nut, shortening the vibrating length of the strings.

With a capo in place, all your familiar open chord shapes remain exactly the same under your fingers — but they sound in a higher key. A capo on fret 2 raises every note by two semitones. Your C chord shape now sounds as D, your G shape sounds as A, and so on.

Types of Capo

🔧 Spring Capo

The most popular type. Squeeze to open, clip onto the neck, release. Quick to attach and remove. Good even pressure across all strings. Available at any music shop — inexpensive and reliable.

🔗 Elastic Capo

A bar with a rubber or elastic strap that wraps around the neck. More adjustable tension but slower to fit. Preferred by some players for its lighter feel. Less common than spring capos today.

✦ How to Fit a Capo

Position the capo immediately behind the fret — just like placing a left-hand finger. Press it firmly enough that all strings ring clearly with no buzzing. Too far back from the fret = buzzing. Too hard = strings sharp. Check tuning after every fitting.

Chord Names at Each Capo Position

When a capo is placed at a fret, all chord names change by the number of that fret position. Use this as your reference chart:

Shape	Capo 1	Capo 2	Capo 3	Capo 4	Capo 5
C	C#/Db	D	D#/Eb	E	F
G	G#/Ab	A	A#/Bb	B	C
D	D#/Eb	E	F	F#/Gb	G
Am	A#m/Bbm	Bm	Cm	C#m/Dbm	Dm
Em	Fm	F#m/Gbm	Gm	G#m/Abm	Am

When to Use a Capo

Matching a singer's key — find the key that suits their voice and use the capo to play there with familiar shapes
Matching a recording — many well-known songs were recorded with a capo; use the same capo position to match the original sound
Accessing bright-sounding keys — keys like Bb and Eb sound great but have few open chords; a capo on fret 1 or 3 lets you play open shapes that sound in those keys
Creating a different tone — a capo higher up the neck gives the guitar a brighter, more chime-like sound, useful for contrasting textures when two guitarists are playing together

⚠ Always Tune After Fitting

Fitting a capo almost always requires retuning. The extra string pressure from the capo bar can push some strings sharp. Always check all 6 strings with a tuner after attaching the capo, before you start playing.
