- Clivis shape:
- Porrectus shape:
Basically, anything that starts with:
<nc tilt="n"/>should have the stem rendered next to the note (not separated with a space as it currently is). This initial nc with @tilt = n usually appears as the first component of neumes that start with a clivis or porrectus shape (the shapes shown above).
And all neumes that have more than one neume component, should have all their neume components connected to one another (with the exception of the rhombuses and repeated notes). See the example of a torculus with the highest neume component being more than a second apart:
An example of the encoding of the torculus in the middle would be:
<neume>
<nc loc="4"/>
<nc loc="6"/>
<nc loc="3"/>
</neume>

The rules for "ligatures"—neumes consisting of more than one neume component—are relatively simple in my opinion. I am using the following real piece for illustrating this (see the manuscript image and encoding):
@tilt=se) must not have connected lines. (You can see a few examples in the second system.)The file for this can be seen in the ECHOES project repo: https://github.com/ECHOES-from-the-Past/GABCtoMEI/blob/main/MEI_outfiles/antiphonae_ad_communionem/002_C02_benedicite-omnes_pem85041_square_SQUARE.mei. I am providing a cleaner version here:
