The Music Papers are an item that you can bring to Agatha.

Locations
A copy can be found in the Springvale School. They are found in the room with the students' desks immediately to the right when you enter the school on the upturned regular desk. Make sure you look as it's not immediately in view.

There is also a copy in Vault 92, in the Living Quarters. It is in the bathroom of the men's quarters. Inside the closed bathroom stall. Behind the toilet.

Another book can be found on the roof of the Statesman Hotel, in the corner. Near the music stands and chairs.

Another can be found in the children's section of the Arlington Library. Past the Firehose Box. Go right. Past the Nuka Cola Machine. In the first room you see enter. In the right cubicle by a music stand on the floor.

Yet another can be found in The National Archives (if i remember correctly the first room in the Archive Sub-Basement)
