THE HISTORY OF MUSIC NOTATION

Many conflicting statements have been made regarding the history and
development of music writing, and the student who is seeking light on
this subject is often at a loss to determine what actually did happen in
the rise of our modern system of writing music. We have one writer for
example asserting that staff notation was begun by drawing a single red
line across the page, this line representing the pitch _f_ (fourth line,
