Parentheses overrides

[James Worlton]

Hi all,

I"m trying to widen the parentheses so the left brace doesn't collide with the sharp. The code I'm trying isn't working. Is this possible?

\version "2.19.15"

parenWider = {

  \once \override ParenthesesItem #'X-extent = #'(-8 . 0)

}

\score {

  \new Staff { \parenWider \parenthesize fis'4 }

}

Thanks,

James Worlton
