Prevent collision/overlap of ties in Lilypond

Question

Running the input

\score {
  \relative c' {
    <c d f g b c>4~
    4
  }
  \layout {
    \context {
      \Score
      \override SpacingSpanner.base-shortest-duration = #(ly:make-moment 1/16)
    }
  }
}

through Lilypond results in the following output:

The ties between the Bs and the Gs cross over each other. What's the best way to fix this (preferably automatically)?

Answer 1

I don't know if this is expected output or not. At any rate, you can override the default placement using the explicit direction specifiers ^ and _. In this case, you need to write the ~ on each note of the chord so you can change its direction individually. For example:

\version "2.22.1"

\relative c' {
  <c d f g b c>1~
  q
  <c_~ d_~ f_~ g^~ b^~ c^~>
  q
}

This syntax is explained here:
