Re: is this a slashed grace?

Hello Ken,




See the attached slashedacciaccworkaround.pdf and .ly.

I hope this may be of use.

I have a workaround for this problem, namely to create an oblique line and move it onto the beam.  I did not use \acciaccatura but rather smaller notes because I wanted to control the spacing of the notes.

   I asked this question regarding a different piece that I was engraving.  It 
looks like the slashed grace as shown in the Lilypond documentation is not the 
same as what I have engraved (there is no slash).
   Now another piece has come up with the same question.
   Maybe these aren't slashed grace notes?  Maybe (as usual) I'm doing 
something wrong?
   My input, my engraving and the origin I'm reading from are attached.

Are you referring to the ornaments is measures 3, 11, and 25?

That's correct.

   A multi-note beamed acciaccatura is printed without a slash,
   and looks exactly the same as a multi-note beamed appoggiatura.

Cheers,
David.
