If you already have a lead sheet …
- Add a 0-line staff (I posted one that works with D5 here)
- Copy the notes and lyrics to it (as lyrics are attached to notes)
- Hide the noteheads, stems, and accidentals. You can do this in Properties panel in Engrave. You can’t hide ties so select all the notes and cut the ties with
U - Remove Rests
- In Setup, set the chord symbols to display on the 0-line staff, then use Select More and move them into position in Engrave.
- Engraving Options / Barlines set Minimum barline protrusion to something larger than the default to get the look you want.
- Hide the time sig on the 0-line staff if you really don’t want it. You may need to input an independent time sig if you want to keep it on your main lead sheet.
