The use of parallel lines to indicate pitch in written music can be traced back to the late-9th century. It developed from an older approach to the description of musical intervals and scales by reference to the strings on two instruments — a single-stringed monochord and a multi-stringed cithara. The latter provided the model for what would become the definitive attribute of staff notation.
The step from plucked string to drawn line is documented in two treatises. One was written ca. 890 by the French monk, Hucbald (b. ca. 840 – d. 930), who in it derived a lined system from a six-stringed instrument. The other is of less certain 9th-century date and unknown authorship. It shows a lined system derived in the same manner and adds a set of symbols called “daseia” to represent notes. (Early manuscript illustrations of both are shown below, as are daseia taken from a font packaged with current music notation software.)
Hucbald was once believed also to have been the anonymous author of the second volume and therefore the deviser of so-called daseian notation. However, none of its symbols appear anywhere in his named work. Both his and daseian notation employ an otherwise identical system of lines. His description of how it was derived from the strings on a cithara is more detailed than the one in the anonymous work, suggesting that lines and daseia appeared successively in the two treatises.
