Re: Grace note spacing & alignment in score

[Lib Lists]

Hi Michael,

I'm also interested in knowing if there's a better solution, but in
the end this is fairly easy to implement, and one can decide how
compressed the grace spacing is by changing its duration. In the
example you posted it makes sense to have the grace notes starting
with the percussion upbeat because the score looks rhythmically neat,
and the spacing gives a realistic idea of the actual duration of the
grace (depending on the tempo).
Interestingly, I found this post from 2019 on Scoring Notes, but
referred to grace notes at the end of a bar
https://www.scoringnotes.com/tips/grace-notes-at-the-end-of-a-bar-in-sibelius/.
Maybe the solution proposed is even better than mine, as it includes
the rest before the grace notes in the same tuplet.
Cheers,
Lib
