Oh, sweet! That was about the easiest thing ever! Thanks for the
tip, Mark & Neil. :) This is much more elegant and useful.
Revised in LSR:
http://lsr.dsi.unimi.it/LSR/Item?u=1&id=616
Here's how it looks now (in case you don't want to go to LSR):
%\version "2.12.2"
stringNumberSpanner = #(define-music-function (parser location
StringNumber) (string?)
#{
\override TextSpanner #'style = #'solid
\override TextSpanner #'font-size = #-5
\override TextSpanner #'(bound-details left
stencil-align-dir-y) = #CENTER
\override TextSpanner #'(bound-details left text) = \markup {
\circle \number $StringNumber }
#})
\relative c {
\clef "treble_8"
\stringNumberSpanner "5"
\textSpannerDown
a8\startTextSpan
b c d e f\stopTextSpan
\stringNumberSpanner "4"
g\startTextSpan a
bes4 a g2\stopTextSpan
}
