decreasing \score after-title-space in \book

[Kieren Richard MacMillan]

Hello, all --

I'm trying to create a \book with multiple \score-s within it. I'm  
having difficulty bringing the first system of the first piece up  
close to its title (see screenshot). The code I've tried is below.

Any help would be appreciated.

Thanks,
Kieren.
