Counting aloud is a very good way to demonstrate features of a metric structure. The most common counting patterns are duple (in twos), triple (in threes), or quadruple (in fours). In the duple structures we have been using, each level could be counted in two’s as in Ex. 5x). Or, as in 5y), the “count 1” of level A could be used as a reference count, meaning that each level below it would begin with “1” only when level A does. Depending on the passage, there may be still other ways to count the same metric structure.
