Export the melody to PDF with paper strips, print it out and cut with scissors.
Make sure to use the right paper size and set you printer scale to 100%, otherwise
the size won't match. It's better when paper strips are thick, so if you are going
to use thin office paper, we recommend you to glue two or three layers together.
Another option is to laminate paper strips with a transparent duct tape
