Forwarding this worthwhile example to the group as Alex probably intended.

I would also like to submit this example from Beethoven’s *Grosse Fuge*,
containing very clearly some grace notes that are belonging, if to
anything, then indeed to the preceding note (alternatively the trill). They
certainly do not *attach* to the following note, since there is none. One
could argue that they are attached to a position (an approach that has its
merits, in my opinion), which would mean that it is pretty much irrelevant
whether that position contains a regular note or a rest. As a side thought,
this would open the question whether grace notes should be allowed to have
positions that do not contain such a regular note or rest in the first

Hi Simon,

In both notated music and in MusicXML, grace notes and appoggiaturas are
not "attached" to notes that follow them (although ties or slurs could
provide such connections, as they do in non-grace-note cases). They simply
precede the following notes, in their order of occurrence on the page or in
a document.

If an application has a notion of attachment, that's up to the application.
MusicXML doesn't need to encode attachment, because music notation doesn't
have an inherent notion of such attachment.

That second scenario (grace note following normal note at the end of a
measure) is not seen in conventional notated music. Although one could
write it and encode it, its interpretation would be unclear to a performer.
It's not so much that the layout is correct or incorrect, as that the
conventional interpretation of a grace note or appoggiatura is dependent on
some normal note that follows it in the same measure.

Hope this helps,

.            .       .    .  . ...Joe

"Bring music to life"

Good afternoon,

Firstly, my comprehension of music notation is not extensive, so please
forgive me if I make any clearly wrong assumptions.

When using notation software, we can add a grace note or appoggiatura to
either the start of a note or after it.
At this point, we can decide to link the notes with a tie, a slur or
nothing as in this manner.

I have two questions :

   1. In MusicXML, how can I detect which to note the grace note is
   attached since there is no tie or slur ?
   2. Is this layout correct specifically for the second scenario ?

Best regards
Simon Giddings
