How interesting!
Do you use Graham's function or do you have something "on your own"?

I hoped normal markups to align automatically beside dynamics if
presents, but John disagreed so I didn't open a discussion about that
on one of the international mailing lists.

  c'4\mp-\markup \italic "dolce"

to produce the quite usual "mp dolce".

[And by the way why not make the traditional note-"text" in italic by
default, since the large majority of musical indications are shaped
this way?]

But this is another discussion, and I think I will come again with that
during the GLISS.

That's great, I mean, a huge improvement for basic users like me.

Actually I was speaking about a way to implement this directly into
your music function.  But I found a workaround using -tweak (in order
to not use this \override before the note), see "myCrescMod" below.

Thanks for the explanation.
It is really agreeable when a wise man takes the time to spread this
information.

By the way I found a solution using another variable that would have
this '-' within its definition.

mycresc = #(define-music-function (parser location mymarkup) (string?)
   (make-music 'CrescendoEvent 'span-direction START
               'span-type 'text 'span-text mymarkup))

myCrescMod = -\tweak #'dash-period #-1.0 -\mycresc "cresc"

{
  c'4\myCrescMod c' c' c'
  c'4\f c' c' c'
}

Cheers,
Xavier
