Okay kiddo, have you ever heard of a music bureau? No? Well, it's a place where people go to help musicians and singers get jobs playing music.
Imagine if you wanted to be a musician and play your music for lots of people but didn't know how to get started. That's where the music bureau comes in. They help connect musicians with people who want to hire them to play music.
Think of the music bureau like a big playground where musicians can go and find new friends to play music with. They also have lots of toys (like instruments) that musicians can use to play music.
So, the music bureau helps musicians find work and gives them the things they need to make great music. That's pretty cool, right?
