Here is my take on how to use a Capo on the guitar and why you might do so.
I’m going to get the controversial bit out of the way first!
And that is – “how is capo pronounced”?
Is it kay-poh (“a” sounding as in plate) or ka-poh (“a” sounding as in bad)?
Most will use the first pronunciation, but occasionally you will hear the second, particularly in Europe. Some would argue the second is the head of a crime family, but that’s a whole new story which doesn’t interest us hobby guitarists!
Use the first pronunciation and you won’t go far wrong and in all honesty, that’s the way most folks do say capo.
Right, so what is this thing used for? (No matter how it is pronounced!)
A capo is really a way of forming a temporary barre so that open chords and strings are higher in pitch and have a new key reference on the guitar.
Put another way, it is like moving the nut of the guitar further up the neck (towards the body and away from the headstock).
If you know how to play barre chords, your finger that is forming the barre across the strings is actually acting a bit like a capo while you play that chord.
And how do you attach it to the guitar?
A capo typically has some sort of bar that goes on the strings and an elastic or other strap that goes round the back of the neck of the guitar and fastens to keep the capo in place.
There are variations using hinged mechanisms and thumb screws to tighten, but the principle is the same – it rests on the strings forming the new reference key and attaches to the neck around the back of the neck of the guitar.
Here I am attaching a capo to one of my guitars and I should warn you now, I pronounce it the second way (ka-poh), but then I’m British and a bit strange that way!)
Much like placing fingers in the right place, just behind the fret, so it is with capos – too far back and the strings will rattle – too close and the strings will sound muffled or dull.
Keep playing the strings occasionally as you adjust the position of the bar of the capo to get the clearest sound you can.
Also, attaching too tightly will actually force the strings down over the fret so much that you will put the guitar out of tune.
The pressure on the strings just needs to be enough to stop the strings from rattling or buzzing on that fret and yet sufficient to get a clear tone from the strings.
Why would you use one?
capos are used mostly on acoustic guitars, more often than not, to raise the pitch of a tune using open chords or strings to match someone’s natural voice register.
The capo simply changes the key of the open strings.
But something else happens as well, and this is just my opinion, but it gives the guitar a slightly different tone which I think of as a more folk tone when used on acoustic guitars.
Scarborough fair by Simon & Garfunkel is a classic example of the use of a capo and is a terrific song as well.
What is it with that tune, I find it pleasing, melancholic and haunting all at the same time – what do you think?
Let’s just ignore that there is considerable doubt over the originality of this song and just enjoy it for the great tune it is.
The capo is being used just behind the 7th fret which effectively tunes the guitar to B tuning (if E is regular tuning, then the 7th fret of the E string is B). I.e., the “open” strings are now from where the capo is positioned and are B, E, A, D, F# and B (thickest to thinnest) – bingo, you’ve got a guitar tuned up by 7 semi-tones.
If you are predominantly an acoustic guitar player, then you’ll probably need or want to use a capo at some stage.
For something different, check out the version of Scarborough Fair by Queensrÿche
So I really hope you now know how to use a capo on the guitar and what it is used for as well as how to attach one in the right way.
I would welcome any comments or questions you might hav; just post them in the comments section and I’ll respond as soon as I can.
All the best and keep on rockin’
