A capo is a clamp that presses across the strings at a fret to raise the pitch of the open strings. Open it, place it just behind the fret you want, and let it close so the pad holds all the strings down evenly. Moving it up the neck raises the pitch; removing it restores the open tuning.
Choose the fret for the pitch you want
Decide how much higher you want the open strings to sound, then move up the neck to reach it. Each fret up the neck raises the pitch by a semitone, so the further up you place the capo, the higher the open strings sound. Place the capo at the fret that matches the key you need, and keep it there while you play.
Place the capo just behind the fret
Squeeze the capo open and set it across the strings just behind the fret wire, with the pad pressing the strings against the fretboard. Let it close and check that it sits straight across the neck. Pluck each string and listen for a clear note. If a string sounds dull or buzzes, slide the capo closer to the fret or release and reposition it until every string rings clearly.
Check the tuning after you clamp it
A capo can pull the strings slightly sharp, so check the tuning once it is in place. Play each string and listen for the pitch you expect. If a string sounds sharp or flat, move the capo closer to the fret and check again. A capo that sits too far from the fret needs more pressure and pulls the strings further out of tune, so keep it close to the fret wire.
Move the capo to change key
To play in a higher key, slide the capo further up the neck and check the tuning again. To return to a lower key, move it back toward the headstock or take it off. Each position gives a different key, so the capo sets the pitch while your hand position stays the same. Release the capo with one hand and reposition it without pulling the strings.
Remove the capo and store it
Squeeze the capo to release it, then lift it straight off the neck without pulling the strings. Do not drag it along the strings or let it snap shut on the fretboard. Wipe the pad and the neck with a soft dry cloth if dust has collected, and keep the capo in its bag so the spring and pad stay clean.

Frequently asked questions
Where should a capo sit on the neck?
Just behind the fret you want, with the pad pressing all the strings evenly. If a string buzzes or sounds dull, slide the capo closer to the fret and check each string again.
Does a capo change the tuning of the guitar?
It raises the pitch of the open strings, and it can pull them slightly sharp. Check the tuning after you clamp it and move it closer to the fret if a string sounds off.
Can I leave a capo on the guitar?
Take it off when you stop playing. A capo left clamped keeps pressure on the strings and the neck, and the pad can collect dust. Store it in its bag until you need it again.
