The conjunctura is a falling group, usually of four notes when in the
upper part (Ex. 166), sometimes of five : (Ex. 167) but in the cadences
there are often six, seven, eight, nine, or even more notes. This caden-
tial occurrence, or copula as it is sometimes called, is so frequent in
some manuscripts as to appear a cliche. The theorists and the test
of concordance in the manuscripts supports them tell us that the
last note of a conjunctura is equivalent to the sum of the time-values
of the others. This is true of a conjunctura of four or five notes run
ning in the text, but it needs modification in the case of some of the
cadential forms employed. Ex. 168 is a cadence used dozens of times
in Wolfenbiittel 677. Ex. 172 is a good instance of the actual use of
the conjunctura in a composition of the period:
