Lyrics and Repeats

[Kaj Persson]

Hi all

In the Notation manual is described how to manage Lyrics in Repeat 
conditions. It shows examples the Repeat section following an initial 
part of music. There are also examples when the Repeat starts the piece 
and then followed by more music. But if you are searching the 
combination of these two you search in vain. This was really what I 
wanted, an initial part before the Repeat then a couple of alternatives 
and an ending part outside of the repeat and alternatives. Well I 
understand the author of the manual who left this case aside, because 
the solution I succeeded to find does not agree with the normal rules 
described in the manual. The rule with repeated { \skip 1 } was changed. 
Instead of counting individual tones, you now has to define whole 
measures. If you do not, the text is gliding away, possibly of the 
score, it vanishes and you cannot find it! I suppose this is a bug that 
ought to be corrected.

Another observation is that \lyricsto adds an extra space at the start 
in the case that you define an new lyric at the beginning of the 
\repeat. So the '\new Lyric \lyricsto "melody" { ' is NOT equivalent 
with '\new Lyric { \set associatedVoice = "melody" '. This too ought to 
be a bug.

To find this took of course a quite lot of time, and I am still not 
shure I have catched the full truth. In the following examlple I have 
used variables for the lyrics, just to test that it work, and it does. 
The interested can also test removing the "% " before the \lyricsto to 
see the consequence.

I am running LilyPond version 2.21.0 via Frescobaldi. Appended an image 
of the Music example.
