Explanation:

In Western classical music, a suite, by definition, means that the piece consists of a set of smaller pieces (or movements) that follow a sequence. They were meant to be accompanied by dances. Although there were 'suite-like' compositions in previous centuries, the suite became defined as we know it until the seventeenth century, which corresponds to the Baroque period.
