\version "2.19.82"

leftBracketPath =
#'((moveto 0 -1)
   (lineto 0 0)
   (lineto 2 0)
   )

rightBracketPath =
#'((lineto 2 0)
   (lineto 2 -1)
   )

treble = {
  \time 2/4

  \once \override TextSpanner.dash-period = #1
  \once \override TextSpanner.bound-details.left.text =
  \markup {
    \path #0.25 #leftBracketPath \general-align #Y #CENTER \sans \upright "
x3"
  }
  \once \override TextSpanner.bound-details.right.text =
  \markup {

    \general-align #Y #CENTER \line { \sans \upright " x3" \path #0.25

  \bar "."
