Okay, so you know how when you walk, you have a certain rhythm in the way your feet go up and down? Cadence in poetry is kinda like that. It's the pattern of beats and sounds that make up a poem's rhythm.
It's like a song without any music. Every time you read a poem out loud, you might notice that some parts sound stronger, like they have an extra oomph or emphasis, while others are softer or weaker. This is because they have different syllables or sounds that make up their cadence.
Sometimes, poems have what's called "meter," which means they have a regular pattern of stressed and unstressed syllables. It's like a dance where you know what steps come next. Other times, poems have a more free-form cadence, where the rhythm might change from line to line depending on what the author is trying to say.
So basically, cadence is the way a poem sounds when you read it out loud, and it can be regular or flexible depending on the poem itself.
