So, when the change in dynamics occurs over a shorter span, say one or two measures, symbols referred to as hairpins are used for crescendos and decrescendos. So, here we see a crescendo mark, which starts on the left side of the hairpin and then opens up. And that symbol, again, is called a crescendo. And means, to gradually get louder.
