You are thinking of LilyPond/Scheme as a procedural language here. What
happens here is that you calculate a suitable override and, well, throw
it away. The return value of this function, calculated later as arg,
does not care what you have

Well, I'm not enthusiastic about both code and interface. The problem
with the code is that
{ c'8-\parenthesize-1 [ f'8] }
will no longer compile.
Ah, I see.
The first reason for that is that one-paren
parenthesize will not work for any

Hi list,
my scheme-fu is a bit rusty, so I tried to get a new start
by enhancing the parenthesize function defined in
ly/music-functions-init.ly with the code to be found in

Here is what I have so far:

I remember getting such error messages in combination with some
unbalanced parentheses, but my editor tells me that this is not the case
here :-(
Found it!
It was unbalanced ''s in the doc string here!

What about
\version 2.19.20
#(define (set-paren-property arg)
(if (memq 'event-chord (ly:music-property arg 'types))
;; arg is an EventChord - set the parenthesize property
