What is a Capo?
A capo is a device that allows you so move the nut of your guitar around. Okay, not really, but if you think of it in those terms you’ll be able to get a lot out of one. Essentially a capo is a strip of hard material (usually rubber or plastic) which is clamped onto the neck of your guitar at a position of your choosing, effectively providing you with a full barre on whatever fret you place it. It is a floating nut, if you will. Capos can look fairly high-tech in spite of their simplicity of function. You can find more about capos, including how to use one to transpose the key of a song (and make it easier to play), in the article The Underappreciated Art of Using a Capo. This answer can be edited and improved by you on the Guitar Noise Wiki. Go to capo and select edit to make improvements.
