<p>Dear all,</p>
<p>Fairly new MEI user, trying to encode some 13th-century Notre
Dame notation into MEI for a class. MEI has good support for many
neumes, but I'm attempting to get them to work in a polyphonic
context, align correctly and with good semantics. Here is a small
example which I'm attempting to encode:</p>
<p><img moz-do-not-send="false"
src="cid:part1.A71D349E.3C156FA6@yokermusic.scot" alt="Small
Notre Dame example." width="612" height="297"></p>
<p>Most of the neumes can be notated and typed with the exception of
the complex neume FGBGA which does not have a name. This is fine
as this music does not stick to the usual neume types.<br>
</p>
<p>My first issue arises when trying to show the first tenor note D
is aligned with the porrectus GFG. How would I go about achieving
this without using semantically-incorrect spacers or invisible
rests or durations? What I really wish for is the possibility to
encode sections of polyphony in groups that are aligned together,
i.e. the first three neumes in the organal voice in one group,
then the porrectus in a new group with the tenor virga.</p>
<p>The second issue is the vertical lines. They are not barlines,
nor always rests. They are divisiones with a complex and
context-sensitive function. Sometimes they function as rests,
sometimes they are alignment marks, sometimes syllable marks.</p>
<p>The first attached file 'benedicamus-domino.mei' encodes this
example naively. Nothing is aligned and I use <barLine>
where divisiones are.</p>
<p>The second attached file 'benedicamus-domino-wish.mei' is how I
wish to encode this file, using a made-up element
<alignmentGrp> that can contain anything a <font size="-1"><</font>section>
contains. I have also replaced the <barLine> with another
made-up element <divisio>.</p>
<p>Needless to say, I'm not concerned with the output in verovio, as
very little neumatic notation is supported anyway, but instead
encoding the alignment and elements correctly. Is something like
this possible in MEI already or will I have to dabble in ODD? If I
must, are there any links to a good workflow and documentation for
using ODD with MEI?</p>
<p>Thanks in advance for responding to this quite complex question,</p>
<p>Joshua Stutter.<br>
