Re: Parenthesis/bracket/brace questions

[Brent Annable]

Hey Andrew,

Wow, this looks like exactly like my score! Thank you very much, I managed to tweak the values of this code to get exactly the shape I needed.

On a side note, in my searches I noticed it's now possible to define different barline types, and the bracket type looks like it would also do the job very well here... but I can't get the brace to span both staves without having 'horns' (there seems to be some weird spanning behaviour too):

\version "2.19.65"

\defineBarLine "[" #'("" "[" ".")

\defineBarLine "]" #'("]" "" ".")

upper = {

  c''4 \bar "[" 4 4 \bar "]" 4

}

lower = {

  \clef bass

  c4 4 4 4

}

\score {

  \new PianoStaff <<

    \new Staff {

      \upper

    }

    \new Staff {

      \lower

    }

  >>

}

Any ideas? I'm stumped.

Brent.

Hi Brent,

Unless I am totally missing the point, this was discussed on the list a couple of years ago, and a simple solution provided oin LSR 957. Is the following not what you want?

1. Does anybody have an idea how to insert large, cross-staff square braces (effectively parenthesizing the entire staff) as in the link below? I have no idea how to even start.
