Using a guitar capo allows you to effectively reposition the nut of
your guitar up to a new fret, increasing the pitch of the open strings.
Obviously you can tune the guitar down, so using a capo can be seen as
tuning up from standard tuning without over stretching and breaking the
strings!
Vocalists
often find the capo useful because it allows them to sing in a more
comfortable register, yet still allow the guitarist to play those
familiar, lush open chord voicings.
First, let's look at the different types of capo you can use...
Types of guitar capo
There
are two main types of capo - strap and clamp. Both serve the same
fundamental purpose - to press down a bar across the strings at a given
fret. It's similar to when you barre your fingers across, i.e. in barre
chords.
Strap capos
As the name suggests, strap capos involve pulling the bar down by
tightening a strap around the back of the neck.
Clamp
capos
Simply
clamps the bar down onto the strings using a spring or locking lever
(by tightening a screw).
Partial
capos
These
are designed to only fret one or a few strings, leaving the others open
as standard. Great for alternate tunings and where you need a low bass
string but higher treble strings.
Attaching and using a guitar capo
Whichever
type of capo you use, the positioning is the same. Make sure the bar of
the capo is positioned close to the fret wire. This is
exactly the same principle as if you were fretting the strings with
your fingers.
Ensure the
capo is straight, in line with the fret wire.
Make
sure that when attaching the capo you don't push any strings out of
place. Make sure all the strings remain in equal spacing apart from
each other, as they would rest naturally.
Ensure the capo is
tight enough by playing each string and listening for any excess
buzzing. The capo will be your "base" so you need it to resonate
without obstruction, just like your open strings would.
Always remove the capo when putting your guitar down for longer than a
few minutes.
How the capo affects tuning and chords
When
using the guitar capo in standard tuning, you'll simply be moving the
pitch of the strings up by a semitone each fret. For example (1st/skinniest string at the top, down to 6th/fattest string)...

This
means if you have the capo at the 1st fret, and you play the standard
open C major chord, you'll in fact be playing C# major. All open chord
pitches will have changed. However, it's simple mathematics - if your
capo is on 4th, for example, that's 4 semitones (or 2 whole steps) from
the open position, so
what would open D major become if it was moved up by that same degree
of 4 semitones?...
D major- Eb - E
- F - F#
major
Barre and
other movable chords will remain unchanged, as they do not use any open
strings and you'll be using the same fret as you would without the
capo. E.g. a G major barre chord will still be played at the 3rd fret,
even if the capo is on the 1st or 2nd.
Using a guitar capo can
provide fresher chord voicings and put your songs in a different key,
often giving them a completely different feel. Experiment with it and
try the capo in different positions, as high as the 5th 6th 7th, even
higher frets.
