Re: temporary staff for divisi

[Mats Bengtsson]

I answer this email for the record.

It seems that there's an attempt to explain this better in the 2.13 
manual than in the 2.12 manual, see 
http://lilypond.org/doc/v2.13/Documentation/notation/Context-layout-order#Context-layout-order 
and 
http://lilypond.org/doc/v2.13/Documentation/notation/Aligning-contexts#Aligning-contexts, 
but it still doesn't really answer your question.

The Staff contexts are ordered vertically in the order they are created. 
The main Staff contexts in \violineA and \violineB are created at the 
same musical moment (at the top of the piece), and in that case, the 
order is determined by the order they appear in the \score{...} block in 
your .ly file. However, the \context Staff = "Two" happens later 
(musically) and is therefore created later so it appears at the bottom 
of the system.

As you have figured out, this can be solved by specifying 
alignAboveContext. An alternative is shown in the template A.4.1 SATB 
vocal score in the Learning manual, which partly is described in 
http://lilypond.org/doc/v2.13/Documentation/notation/Entering-lyrics#Working-with-lyrics-and-variables
