Manual repeat and line break.

[Walt North]

Well... after sending this I started thinking about a different question I had asked a while back and realized I could leverage that to get what I need.   it's not really ideal but it will work.

Refer to code below and the screen shot. Once i get the structure laid out I'll work on making it prettier.

The desired end result to match the James Taylor song (plus some extra parts I'm adding in) is :

AA BB CC

BB DD

AA BB EE

AA  FF

Note of course each of these will be much longer than just two measures in the real song. And that D D, E E, and F F do match each other structurally otherwise I could have taken a simpler approach.

    \layout {
      \context {
        \ChordNames
        \override BarLine.bar-extent = #'(0 . 2)
        \consists "Bar_engraver"
      }
    }
    
    ch = \chordmode {
      a1 a \break
      \repeat volta 2 {
        b b
        \alternative {
          \volta 1 { c c }
        }
      }
      <<
        \chordmode { d d  \break e e  \break f f  }
        \chordmode {
          \set Score.repeatCommands = #'((volta #f) (volta "2.")
    end-repeat)
