Jean,

I think \translate-scaled will work for me! This is a wonderful tool.  In the following example, \concat allows me to get the symbols closer together. The -.2 values for x in /translate-scaled on the third \markup example do nothing. Is there a way to turn off collision avoidance in \markup? I know about \once \override TextScript.extra-offset = #'(0 . 0) , but that does not scale.

\concat is not the tool you want here. Basically, \translate-scaled moves the markup on an imaginary grid, but \concat then ignores the placement of the translated markup on this grid by realigning its left edge to the right edge of the previous element, to bring the two elements as close to each other as possible. Try this instead:

\version "2.24.1"

chord =
\markup \overlay {
  C
  \translate-scaled #'(1.8 . .4) \fontsize #-1 \flat
  \fontsize #-2 \column {
    \translate-scaled #'(3.1 . 1.2) 7
    \translate-scaled #'(3.1 . 2.5) 4
  }
}

{ 
  \textLengthOn
  c1^\markup \fontsize #5 \chord
  c1^\markup \fontsize #10 \chord
  c1^\markup \fontsize #5 \chord
}
