I've found what seems to me to be a common musical pattern in several different pieces, and I'm wondering if this pattern has a name.
Here's the pattern: the metaphorical musical train is chugging along at a pretty good pace, then the composer brings it to a grinding halt with a ritardando, which leads to a massive 'a tempo'.
