Thanks for this answer.
So IIUC the dash between the end of the tweak and the ly:music?
argument is mandatory, as well as the one between the note and the
\notToBarline ?
That's the two things I missed when I tried a music function with the
ly:music? argument.

Yes, this is nice.  At least I can use it with different grobs.

I would like to be able to get rid of the dash between the note and
\notToBarline .
But I do not think it is worth going into huge work only for me to
meet my aesthetic desire (but if someone else is interested in this
define-event-function and if this is implemented, I would be happy to
use it of course).  ;-)

Thank you.

Cheers,
