RE: Ddoubled parentheses

[Mogens Lemvig Hansen]

Thanks Aaron.

 

Looking at http://lilypond.org/doc/v2.18/Documentation/notation/visibility-of-objects#index-_005comit

I would have expected the syntax to be

   \new NullVoice \with { \omit Score.ParenthesesItem } { \music }

and I would have expected that to eliminate the parentheses in _all_ voices – but only the NullVoice is affected.  This is of course wonderful for my case, but I don’t understand why it works that way.

 

I need to become less scared of the Internals Reference.

 

Regards,

Mogens

The default location for the Parenthesis_engraver is the Score context,

that is why removing it from the NullVoice has no effect.

 

The simplest option I see is this:

 

%%%%

\version "2.18.2"

 

music = \relative {

   c' e \parenthesize g c

}

 

\score {

   \new Staff <<

     \new Voice { \music }

     \new NullVoice \with { \omit ParenthesesItem } { \music }

   >>

}

%%%%
