I'm trying to set the Bodleian MS. Canon. Misc. 213 (early renaissance manuscript, perhaps the first in void mensural notation) in a form that captures most of the peculiarities of the copyist's notation, but uniformly readable. I've solved several of the problems, but ...
The copyist uses a variant of the descending semibreves mensural ligature, with a slanting box instead of the two square noteheads (this is shown in the Wikipedia page on Mensural Notation http://en.wikipedia.org/wiki/Mensural_notation#Ligatures in the leftmost entry on line 5 of the table). The notation looks just like the descending breve ligature, except that the stem goes up instead of down. I don't expect the Lilypond mensural notation to provide this variant directly, so I'm trying to find the right tweak in the source. There seems to be no hook for mensural ligatures in the Scheme source. I have stared at mensural-ligature-engraver.cc and mensural-ligature.cc without absorbing any clue as to where/how the choices involved in creating ligatures are actually made. It appears that there should be some invocation of spanners and maybe beams to generate the slanted forms, but I can't find the right spot in the code. So, pointers into the code will be highly appreciated. Of course, if someone wants to provide selectable variant ligature forms, ... :-) When I've accomplished enough to make a useful example, I'll post some of my techniques.
