in the Italian music, denotes a quick time, peculiar to jigs. This species of time is otherwise called the measure of nine times, which requires two falls of the hand, and one rise. There are three sorts of nonupla:

1. *Nonupla di semi-minime*, or *dupla semiquarta*, thus marked $\frac{2}{9}$, where nine crotchets are to be in the bar, of which four make a semi-breve in common time, i.e., in the down stroke six, and but three up: it is usually beat adagio. 2. *Nonupla di crome*, or *semiqua ottava*, marked thus $\frac{3}{9}$, wherein nine quavers make a bar instead of eight in common time, i.e., six down and three up: it is beat presto. 3. *Nonupla di semi-crome* or *super feti partiente nona*, thus distinguished $\frac{4}{9}$, in which nine semi-quavers are contained in a bar, whereof sixteen are required in common time, six down, and three up: it is ordinarily beat prestissimo. Beside these, there are two other species of nonupla, for which see TRIPLE.
