Ligatures and Musical Meaning

In mensural notation, certain combinations of notes could be notated either individually or bound together as ligatures. The choice of whether or not to use a ligature provided an opportunity for composers and scribes to encode different types of musical meaning. It has long been accepted that ligatures could help to show text underlay, and scholars have also proposed that ligatures could clarify aspects of musical structure, such as melodic and rhythmic patterns, phrasing, and articulation. It is difficult to prove wide applicability of these proposals, not least because they tend to rely primarily on the evidence of practical sources. Fortunately, there is more theoretical evidence about the purpose and function of ligatures than has been heretofore recognized. While much of the evidence unsurprisingly points toward the textual significance of ligatures, a substantial amount of theory from the early fifteenth century to the midsixteenth century shows that ligatures were also important for clarifying aspects of mensural context, sometimes forcing perfection and alteration. The evidence leads us to reconsider widely held assumptions about the significance of ligatures and to look beyond text underlay as the primary meaning that may (or may not) be signified. Drawing on these insights, contextual analysis of notation can provide a clearer window into the concerns and priorities of composers and scribes.
