"set-global-staff-size..." puzzle

[Tom Cloyd]

I suspect this is simple - but not for me.

I've tried hard to solve this one myself, but I'm not coming up with 
ANYTHING helpful anywhere.

If I have

"#(set-global-staff-size 20)"

in my code, I get  6 staffs spread across 1.5 pages (#6 is all that's on 
page 2). If I set the size to 18, I get the crowded onto one page with 
2" at the bottom.

I cannot figure out what's happening, or how to get better control of 
spacing between staffs.


Also, the title of the piece is too high on the page. I can set a 
top-margin, but it's ignored. Can't find documentation on how to control 
this either.

Here's the top part of my code...

\version "2.10.0"

#(set-global-staff-size 20) % 20 this is said to be standard for most 
scores  

\paper {
   #(set-default-paper-size "letter" 'portrait)       
   ragged-last-bottom = ##t % turns off vertical justify
   left-margin = 0.6\in
   line-width = 7\in     % works better than specifying R-margin
   bottom-margin = .7\in
   top-margin = 0.15\in   
}

\layout {
   indent = 0.0\cm % remove indent on first staff
}

\header {
   title = "Prelude #2"
   subtitle = "A legato etude for classical guitar (2008.08.13)"
   composer = "Tom Cloyd"                                                 
   tagline = \markup { \small "score set by Tom Cloyd - with Lilipond - 
address@hidden"} % this is the copyright line   
}

Thanks in advance for any suggestions anyone has!
