A field holler is a type of song that people use to communicate with each other while working in a field. It's like a very special kind of song that you sing to help you do your work better.
Imagine you and your friends are outside in a big field picking berries all day long. Picking berries is hard work, and sometimes it can feel really boring. But you also want to talk to your friends and let them know how you're doing, or share something funny you just thought of.
So instead of just shouting or talking to each other, you might start singing a song. This song would be special because it would have a really simple melody that everyone could remember, and you could change up the words to fit whatever you wanted to say. For example, you could sing something like:
"Pickin' berries all day long,
Ain't nothin' gonna keep us down.
We'll keep workin' hard and strong,
Til the sun goes down."
And then your friends might join in or add their own words, like:
"Got a big ole basket here,
Gonna fill it up with juicy pears."
Everyone would be singing and working together, and it would make the work go by faster and be more fun. That's what a field holler is!
