Re: [bug?] \lyricsto with lyrics above notes

[Mats Bengtsson]

Actually, it seems the for the moment it is even better to
use { } instead of the {s1}. Consider for example the following
(somewhat but not extremely contrived) example:

\version "2.2.6"
\score{
<<
  \context Lyrics = sopranos \notes { } % Lyrics above
%  \context Lyrics = sopranos \notes { s1*10 } % Lyrics above
%  \context Lyrics = sopranos \notes { s1 } % Lyrics below
  \context Voice = sopranos  \notes \relative c'{R1*10^"Intro." <<  { 
r2 c | e g c1 }
  \context Lyrics = sopranos \lyricsto sopranos \lyrics{A ly -- rics 
line } >>}
>>
}

where the { s1 } does not keep the context alive long enough for
the actual lyrics to start, so you need {s1*10}. However, for some
reason it also works if you only say { }. I'm pretty sure that the
latter option did not work in early versions of LilyPond, whereas
the {s1*10} trick has been around as long as we have had \addlyrics
(the predecessor of \lyricsto).
