Re: Identifying to which note a grace note is attached

Hi Joe and Simon,

"not seen in conventional notated music"?

In capella, we support both appoggiatura and passing appoggiatura. In 
German, the terms are Vorschlag and Nachschlag. I find various examples 
for Nachschlag 
(https://de.wikipedia.org/wiki/Verzierung_(Musik)#Nachschlag 
<https://de.wikipedia.org/wiki/Verzierung_%28Musik%29#Nachschlag>, 
http://www.klavier-noten.com/musik-literatur/VERZIERUNGEN.pdf), but none 
for passing appoggiatura. Maybe passing appoggiatura it is not the 
correct English term. But Nachschlag seems to be well known.
In our MusicXML export, we use the steal-time-previous attribute for 
Nachschlag notes, and hope that the steal-time-following attribute 
(documented "as for appoggiaturas"), will be implicitly applied if the 
note has a <grace/> element.

Kind regards,
Bernd Jungmann
