Here's a working solution that you can customize to your taste (the width
of the new markups, controlled by the \draw-line command's x-component, may
need to be adjusted depending on the horizontal spacing of your intended
usage):
%%%%%%%%%%%%%%%%
\version "2.18.2"
heelToToe = \markup {
\halign #-1.2
\concat{
\raise #0.5
\musicglyph #"scripts.upedalheel"
\hspace #0.5
\with-dimensions #'(0 . 0) #'(0 . 0) \concat {
\draw-line #'(3 . -5.5) % <-- controls width
\lower #5.5 \musicglyph #"scripts.dpedaltoe"
}
}
}
toeToHeel = \markup {
\halign #-1.3
\concat{
\musicglyph #"scripts.dpedaltoe"
\with-dimensions #'(0 . 0) #'(0 . 0) \concat {
\draw-line #'(3 . 5) % <-- controls width
\raise #5.5 \musicglyph #"scripts.upedalheel"
}
}
}
music = {
\clef bass
c,2_\rtoe g,^\heelToToe |
c2^\heelToToe g^\heelToToe |
c'2\rtoe g_\toeToHeel |
c2_\toeToHeel c,_\rtoe \bar "|."
}
{ \music }
\layout {
indent = 0
ragged-right = ##f
}
