    A ligature is a coherent graphical symbol that represents at least
 two distinct notes.  Ligatures originally appeared in the manuscripts of
 Gregorian chant notation around the 9th century to denote ascending or
 descending sequences of notes.  In early notation, ligatures were used
 for monophonic tunes (Gregorian chant) and very soon denoted also the
 way of performance in the sense of articulation.  With the invention of
 the metric system of the white mensural notation, the need for ligatures
 to denote such patterns disappeared.
