Do you mean something like the following (which duplicates the image you've
uploaded)?
\version "2.15.32"
#(define-markup-command (mbarre layout props fretnum vdrop offset) (markup?
number? number?)
(interpret-markup layout props
#{
\markup \translate #(cons offset 0) \small \bold { \concat {
\postscript #(string-append "0.1 setlinewidth 0.7 -0.5 moveto 0 -"
(number->string vdrop) " rlineto 0.5 0 rlineto stroke") $fretnum } }
#}
)
)
\relative c'' {
<e c>4^\markup { \mbarre "V" #2.3 #0 } <e c>^\markup { \mbarre "V" #2.3
#-1.5 }
}
HTH,
David
