10. Bach Well Tempered Clavier doodle
It might just look like a squiggle on the top of the page, but it's actually Bach's incredibly geeky way of explaining how to tune the keyboard before playing. The doodles are read from right to left, with the letter C beneath the doodle indicating where the C lies, with each different kind of loop representing the intervals to be used.
