Re: Avoid double beaming

[Valentin Petzel]

Hi Jogchum,

the reason for your issues is that you are using voice 2 (i.e. lowest voice) 
with a \stemUp, which will cause issues to resolve collision. Generally you 
should avoid using \stemUp and \stemDown unless you really need to use it and 
rather use the correct Voice.

If you were to use \voiceThree instead (which is the second highest voice) the 
Lilypond will properly resolve collision:

\version "2.24.0"

global = {
  \key c \major
  \time 3/4
}

sopranoVoice = \relative c'' {
  \global
  \dynamicUp
  <<
    \new Voice {
      \voiceOne
      r8 a^\p a4. g8 \time 2/4
      f g a a
    }
    \new Voice {
      \voiceThree
      r8 f f4.(e8)
      d e f f
    }
  >>
}

\score {
  \new Staff \with {
    instrumentName = "Sopraan"
    shortInstrumentName = "S."
  } { \sopranoVoice }
  \layout { }
}


But in your case I suppose you do not actually want to have two voices but 
chords:

\version "2.24.0"

global = {
  \key c \major
  \time 3/4
}

sopranoVoice = \relative c'' {
  \global
  \dynamicUp
  <<
    {
      r8 a^\p a4. g8 \time 2/4
      f g a a
    }
    {
      r8 f f4.(e8)
      d e f f
    }
  >>
}

\score {
  \new Staff \with {
    instrumentName = "Sopraan"
    shortInstrumentName = "S."
  } { \sopranoVoice }
  \layout { }
}

Cheers,
Valentin
