Have a look at music-scheme.cc in the Lily source files

LY_DEFINE (ly_music_property, "ly:music-property",
           2, 1, 0, (SCM mus, SCM sym, SCM val),
           "Return the value for property @var{sym} of music expression"
           " @var{mus}.  If no value is found, return @var{val} or"
           " @code{'()} if @var{val} is not specified.")

HTH but don't ask me to explain it!
