Re: Colored hairpins?

[Tim Reeves]

Well, it helps some, but why do I get
an error when I try the same thing with hairpins?

error: syntax error, unexpected EVENT_IDENTIFIER

         
      r4 d4 \p d d | \repeat "unfold"
4 {d1~} | d1 \once \override Hairpin #'color = #blue   \cr | d1 |
d1 \f

(using 2.11.43 on Windows XP)

and where can I put the variable redDyn
in my .ly file? Everywhere I try seems to give me errors, which is why
I just put the \override right in with the music.

Finally, when does one have to include
the context, like \once \override Voice.DynamicText #'color = #blue?

Thanks for your help.

Dynamics are DynamicText graphical objects (grobs); if you look at  
the bottom of the corresponding page

     <http://lilypond.org/doc/v2.11/Documentation/user/lilypond-
internals/DynamicText#DynamicText>

you'll see that one of the interfaces DynamicText supports is the  
grob-interface; on *that* page (which is conveniently linked),

     <http://lilypond.org/doc/v2.11/Documentation/user/lilypond-
internals/grob_002dinterface#grob_002dinterface>

you'll find the property to set. To save you the trouble (this  
time ;) I've included it here, as a variable:

     redDyn = \once \override DynamicText #'color = #red

Anything that inherits the grob-interface *should* be color-able...  
and that's just about everything in the 'Pond.  =)

HTH,
