Re: note collision - shift voiceOne to left

[Jakob Pedersen]

    Hello Carolyn,
    
    I think what you are asking for is making it look something like
    this:

    I made that using a graphics program, not lilypond.
    
    While I get why you'd want it to look the same as similar places, I
    think that 1) this is harder to read, because it looks like the
    first crotchet is positioned where the second beat of the
      measure would be, and 2) the lilypond placement on the left of the
      dotted minim is the "right" or at least standard way of
      typesetting this type of collision.
      
      Best wishes,
      Jakob

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

Hi, Carolyn!

The default when there are two voices with colliding notes is to shift the voice with upstems (odd-numbered voices) to the right and voices with downstems to the left.  I would like the opposite - i.e. voiceOne, with stems up, shifted left.  Is this possible?  (not as a single override, but throughout the entire piece)

I trust you've seen this section in the NR on collision resolution, but if not, here it is:

https://lilypond.org/doc/v2.24/Documentation/notation/multiple-voices#collision-resolution 

Do any of these techniques not help? And if not, perhaps you could show a screenshot or provide a small example of the shifting you don't want so we can target the problem.

Hope that helps,

Abraham
