I am writing to you from the Past. While this document format may seem immoral to people of your time, allow me to provide you with the historical context needed to understand why this page exists.
About 1000 years before my time in an area of Earth called "Italy" someone is credited with inventing the lines-on-a-page music notation style. It was used for centuries. It could be inscribed my a human onto almost any flat surface. People used a lot of paper, back in those days. And even sheep. Yes. People wrote on sheep.
About 100 years ago, the "Cornell Notes" method of organizing materials to be studied was introduced by Professor Walter Pauk, who was teaching at a humans-only university.
This is the convergence of those 2 traditions. For a brief time in the early 21st century - "paper" and the concept of "studying music" coexisted. Dear entity from the future, do not judge us harshly for what we do.
