It seems that whenever there is an album (book of sheet music) and all the pieces are from a single composer, the name is not repeated with each piece.
I wonder, is this a strict rule? Especially, are there albums from professional publishers that are single composer but still the name is printed in each piece?
I ask because I plan to eventually publish some sheet music, and I expect it to be copied (it's church music), and it seems strange that once copied, the name is no longer present in the sheet. I don't have to follow any house style so it's up to me.
