[MEI-L] Sample encoding of mensural notation

[Martha Thomae]

Hi Daniel,

I took a look at your files. I think the mistake is the way that the dots
are encoded. In Mensural MEI you don't use the attribute @dots. Any dot
after a note is encoded as an element <dot/>. And if this dot is behaving
as a "dot of addition" (which is called "dot of augmentation") you have to
add two attributes: @num and @numbase. These attributes change the note's
value. If the dot is a 'dot of augmentation' you should use @num="2" and
@numbase="3" (this will make your note 1.5 times its original value).

There is an example in the Verovio file that we talked about. So for a dot
of addition you must do:

<note pname="b" dur="semiminima" oct="4" num="2" numbase="3"/><!--
augm --><dot/>


I made these changes to your file and all voices lined up except for the
tenor. I realized this is because the <rest dur="longa"/> at the beginning
is given a duration of 3 breves instead of 2 breves, this is not a mistake
in your encoding, but in the way Verovio is interpreting that "longa" rest.
I will raise an issue about it. Besides that, everything should be working
fine.

Hope this helps,

Martha
