Comb and paper is a rudimentary musical instrument which consists of a comb with a piece of paper pressed to it. To play it, one has to press their lips to the paper pressed to the comb and sing or vocalize into it. The voice makes the paper vibrate and changes the voice quality. The 1911 Encyclopedia Britannica refers to it as "the comb-music of the nursery". "Comb and paper" belongs to the category of "singing membranophones", sometimes called "mirlitons" after "mirliton", another name for the eunuch flute.
