As my daughter learns the guitar I am learning a lot of new terms along with her. I never knew what a “capo” was, until it was explained to me as being a type of clamp that would clamp the guitar’s strings at a certain fret to change the sound of the guitar. I found this pretty interesting and now I know I have a lot to learn when it comes to giving my daughter what she needs for her guitar. You can find a capo from musicians friend. I saw the various capo’s there and am not sure what my daughter will need as she progresses, but I am confident of being able to find the right one.
