Questions & Answers about En la feria hay un coro de niñas y niños que canta canciones tradicionales.

Why is it en la feria and not a la feria?

En usually means in / at and describes location: en la feria = at the fair or in the fairground.
A usually means to, indicating movement toward something: voy a la feria = I’m going to the fair.
Here we’re describing where the choir is located, not movement, so en la feria is correct.

Why do we use hay instead of está in En la feria hay un coro…?

Hay is used to say there is / there are to introduce the existence of something: hay un coro = there is a choir.
Estar (e.g. está, están) is used for the specific location of something that is already known or identified:

• El coro está en la feria = The choir is at the fair. (we already know about “the choir”)
  Here the sentence is first introducing the choir, so Spanish uses hay.

Why is it un coro de niñas y niños and not un coro de niños only?

In traditional Spanish, niños (masculine plural) can refer to a mixed group of boys and girls.
However, many speakers now prefer to name both genders explicitly for inclusiveness: niñas y niños (girls and boys).
So un coro de niñas y niños emphasizes that the choir includes both girls and boys, instead of using the generic masculine.
