The six-note figures is hundreds or thousands of years old, and is part of public domain folklore. However, not being artistic, I copied (and altered) the graphic from the website given. I'm not 100% sure that a simple basic rendering of these six notes in musical staff notation does not create a new copyrighted work. If it does, let me know and I will create a duplicate myself (it will look identical to the current graphic, so this seems kind of silly...)
