Re: Mordant Specification Inconsistancy

Unfortunately there seems to be no authoritative answer to this conundrum! 
As Gerou and Lusk put it[1], "the interpretation of an ornament varies 
according to the musical period or composer. It is advised to consult 
detailed references on ornament usage and interpretation."

One such authoritative source is Frederick Niemann's "Ornamentation in 
Baroque and Post-Baroque Music" (Princeton University Press, 1983, ISBN 
9780691027074).

I spent ages when I was putting SMuFL together trying to get definitive 
answers to these questions, and in the end had to give up. I tried to 
follow Niemann's research where possible.

Subject:        Mordant Specification Inconsistancy



Dear All, 

I've just found an inconsistency in the documentation regarding to the 
mordent element and any kind of help would be appreciated.
If you please look at the SMuFL specification: 
https://w3c.github.io/smufl/gitbook/tables/common-ornaments.html chapter 
4.46,
you will see the mordent glyph is the one without vertical line, whereas 
the inverted-mordent has the line.
If you now take a look at the musicXML documentation: 
http://usermanuals.musicxml.com/MusicXML/MusicXML.htm#EL-MusicXML-mordent.htm#kanchor1196

, you will see the exact opposite. The mordent has a vertical line and the 
inverted-mordent doesn’t. 
I performed some quick web searches and it appears that the meaning of the 
mordent has changed during the history, therefore I can’t decide for 
myself which is the good one.

So does anybody please tell me more about that, or do I miss something ? 
Best regards.
