Possibly using named arguments, so

(make-pango-font-tree "FreeSerif" "FreeSans" "Inconsolata"
   #:music "lilyjazz" #:brace "gonville")

Though I am not overly happy with what would be the required and what
would be the optional font arguments.

Maybe recycling the same function name is not really worth the trouble.
A backward compatible interface seems to create more trouble than it
solves.
