Yes, but I see some weaknesses in our docs.
- Glossary: staff should link to system
- Glossary: both staff and system could benefit from images
- Learning: add some link(s) to Glossary: system. Currently we
have none!
address@hidden:~/src/lilypond/Documentation/learning$ git grep
"@rgloss{system}"
I would recommend adding this to Learning 2 Tutorial. Maybe
somewhere in 2.3 Multiple notes at once; maybe somewhere in
2.5 Final touches. I'll let somebody else think about it in more
detail and produce a patch.
