Your lyrics need to be told which notes they are attached to.

I've not used gregorian.ly to do chanting like this, but it

Is there a particular reason you don't just try it out?
Let me quote from the documentation (Extending LilyPond Guide):
2.1 LilyPond code blocks
Creating music expressions in Scheme can be tedious, as they are heavily
nested and the resulting Scheme code is large. For some simple tasks
this can be avoided by using LilyPond code blocks, which enable common
LilyPond syntax to be used within Scheme.
LilyPond code blocks look like
#{ LILYPOND CODE #}
Here is a trivial example:
ritpp = #(define-event-function () ()
#{ ^"rit." \pp #}
)
{ c'4 e'4\ritpp g'2 }
[image src="lilypond/f3/lily-a1c2820d.png" alt="[image of music]"
text="image of music"]
LilyPond code blocks can be used anywhere where you can write Scheme
code. The Scheme reader actually is changed for accommodating LilyPond
code blocks and can deal with embedded Scheme expressions starting with
‘$’ and ‘#’.
The reader extracts the LilyPond code block and generates a runtime
call to the LilyPond parser to interpret the LilyPond code. Scheme
expressions embedded in the LilyPond code are evaluated in the lexical
environment of the LilyPond code block, so all local variables and
function parameters available at the point the LilyPond code block is
written may be accessed. Variables defined in other Scheme modules,
like the modules containing ‘\header’ and ‘\layout’ blocks, are not
accessible as Scheme variables, i.e. prefixed with ‘#’, but they are
accessible as LilyPond variables, i.e. prefixed with ‘\’.

It would be nice if there were a way to attach the fermata to the tremolo as a whole and do this placement automatically. Likewise, in a project I'm working on with Urs Liska, we're having to do a lot of extra code to get proper fermatas on the final barlines of score sections, which I would also like to see as something that … doesn't need all that extra code.

Re: End of file event
Hi, The situation is that I want to write out my statistical info collected during the score block processing to an external CSV. In my case students are given a lilypond file template which they need to use. This template contains a single score block in which they need to put their work. However, some students are rather creative, and spread out the same work over multiple score blocks. It is very unlikely that they will use book for structuring and in the rare case that might happen I can always edit it out manually. So, it looks like wrapping the toplevel-book-handler and adding my own stats writing will be exactly what I need.

All of the processing of top level expressions (also book level expressions) is done through hooks. You can replace those hooks with your own, call the underlying function yourself, and then work with stats. It will still not give you an "end-of-file" hook, though. However, if they don't use books for structuring the input, all collected scores at the end of file are placed into one book and processed then, so the book processing hook might still be good for you. The respective hooks are set with ly/declarations-init.ly:#(define toplevel-book-handler print-book-with-defaults) ly/declarations-init.ly:#(define toplevel-bookpart-handler collect-bookpart-for-book) ly/declarations-init.ly:#(define toplevel-music-handler collect-music-for-book) ly/declarations-init.ly:#(define toplevel-score-handler collect-scores-for-book) ly/declarations-init.ly:#(define toplevel-text-handler collect-scores-for-book) -- David Kastrup ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
