Thanks Abraham
I have read that section again and I am still a bit confused at what I am
seeing in this attempt at a MWE. In bar 2 the voiceTwo notes are shifted
right, but in bar 5 the voiceOne note, a dotted note, is being shifted to the
right. I have tried using the Staff.NoteCollision.prefer-dotted-right override
but that doesn’t seem to help. In bar 7 there is a different construct with
temporary voices and there the shifting looks like what I want. I am trying to
get the dotted stemUp note in bar 5 to be shifted left.

\version "2.24.0"
\include "english.ly"
SopranoMusic = \relative c'
{
fs4 fs e | d d d | b'2 b4 | a d, e | d2.^\markup "why right?" | s2. | s2.
}
AltoMusic = \relative c'
{
d4 d cs | b cs c | b2 d4 | d d cs | d4 d e | << { fs4 e d | e2. } \\ { d2 s4
| d b cs } >>
}
\score {
\new Staff
<<
\key d \major
\time 3/4
\new Voice = "sopranos"
{
\override Staff.NoteCollision.prefer-dotted-right = ##f
\voiceOne
<<
{ \SopranoMusic }
>>
}
\new Voice = "altos"
{
\voiceTwo
<<
{ \AltoMusic }
>>
}
>>
\layout { }
}
Thanks,
Carolyn
