Hi there,

I'm trying to get my parenthesized trill notes to stop colliding with ties, and I think there are a couple things I can learn by solving this problem.

First, I can't tell why the collision is happening -- is there a best practice for figuring out why elements collide?

Second, I know that some collisions happen because of engraver order. Is there a place I can look to see the default order of engravers, and how I can change this order?

If the collision should be avoided by changing padding, it looks like I might want to add some overrides to the PitchedTrillEngraver's TrillPitchGroup grob at the level of the voice context (according to the Internals reference).

thanks for taking a look,
Jeff

Here are two ways of fixing such collisions manually:

\new Staff \relative c'' {

  % Collision:

  \pitchedTrill b1~\startTrillSpan d b1\stopTrillSpan

  

  % Fixed by moving tie:

  \once \override Tie #'Y-offset = #0.75

  \pitchedTrill b1~\startTrillSpan d b1\stopTrillSpan

  

  % Fixed by reshaping tie (2.16+):

  \shape Tie #'((0 . 0.5) (0 . 0.75) (0 . 0.75) (0 . 0.5))

  \pitchedTrill b1~\startTrillSpan d b1\stopTrillSpan

}

But it seems to me that you want an automated solution, so this probably isn't very helpful.
