For a "guitar" that actually produces different pitches, you will need:
--cereal box or kleenex box
--rubber bands of varying lengths/thicknesses
--2 to 3 pencils, preferably the same diameter (for under the "strings")
--paper towel tube, if you want a "neck", to look like a guitar.(not necessary for making sound)
--scissors
