Wetcircuit gave a perfect answer in their comment, but I want to get this question off of the unanswered list. As mentioned, these are "cumulative tales," which are well-suited for tragic tales as they depend on progressively accumulating detail that concludes suddenly. The German tale "Little Louse and Little Flea" is a fine example, ending with the "cumulative" summary and the traditionally sobering denouement:
Little louse has burned herself to death.
Little flea is crying.
Little door is creaking.
Little broom is sweeping.
Little cart is running.
Little manure pile is burning.
Little tree is shaking.
"Oh," said the spring, "then I will begin to flow," and it began to flow furiously. And everything drowned in the water: the girl, the little tree, the little manure pile, the little cart, the little broom, the little door, the little flea, and the little louse, all together.
A Companion to the Fairy Tale includes the chapter "Catch if you can: The Cumulative Tale," which provides some interesting commentary on the structure and history of the cumulative tale, although only a portion of the chapter is freely available:
Rather like a constructed tower of cards, the tale extends itself until it reaches the inevitable collapse – at its best, a resounding memory-racking crescendo of accumulations, which then abruptly stops. With the cumulative tale, the repetitive pattern takes precedence over the plot or, some might say, is the plot. Essentially, the tale exists to add to or multiply itself via those accumulations.
