Re: Context creation

[Mats Bengtsson]

How about the following example of how to get an ossia stave for 
alternative versions of the music.
The method described in the manual is somewhat clumsy since you have to 
count the number of
bars to know what \skip commands to insert between each ossia. Here, you 
can enter the two
versions of the music together.

\version "2.10"
\relative c' <<
 \new Staff = ossia \with
 {
   %No time signature in the ossia staff
   \remove "Time_signature_engraver"
   fontSize = #-3
   \override StaffSymbol #'staff-space = #(magstep -3)
   \override StaffSymbol #'thickness = # (magstep -3)
   firstClef = ##f
 }  {\stopStaff s1*4} % Keep the context alive during the full score
 \new Staff {
 c4 d e f |
 << { g a b c }
    \context Staff = ossia {\startStaff g8 f g a b a b c \stopStaff } >> |
 b4 a g f |
 << { e4 d c2 }
    \context Staff = ossia {\startStaff e8 f e d c2 \stopStaff } >> |
 }
>>


Another fine detail about the difference between \new and \context is 
that if you do
<<
\new Staff = one { c d e f }
\new Staff = one { g f e d }
>>
then LilyPond will take the word "new" more seriously than the "= one", 
i.e. even though you
specify the same name to both staves, you will get a new copy since you 
used \new and not
\context on the second line.
