Re: The behavior of a \score block

[Mats Bengtsson]

There's no need for the \new Score in this situation. You can just as 
well do the setting
in the \layout block:
\score {
 <<
   \new Staff { c''1 \mark "molto" c'' }
   \new Staff { c'1 \mark "molto" c' }
 >>
 \layout{
   \context {
     \Score
     \remove "Mark_engraver"
     \remove "Staff_collecting_engraver"
   }
   \context {
     \Staff
     \consists "Mark_engraver"
     \consists "Staff_collecting_engraver"
   }
 }
 \header {
   piece = "a Score within a \score!"
 }
}

Here, I also moved the redefinition of the Staff contexts into the 
\layout block, which is not necessary
but saves some typing in this particular example, since all the Staff 
contexts should have the same
definition.

In general, I cannot think of any situation where \new Score is really 
needed. I searched a bit
in the mailing list archives, and found one early mention of this 
feature in 
http://lists.gnu.org/archive/html/lilypond-devel/2004-02/msg00098.html
From there, it seems that the main reason to allow for \new Score was 
for symmetry with
all other contexts, like Staff and Voice, where you can tweak the 
context using \new Xxxx \with ...
