- Line breaks does work with \break. For a jazz chord chart, I want exactly 4 mesures on each line, and equally spaced. Does anyone know how to obtain that ? I'm not much familiar with the contexts.
- I would like to have the lines closer. I tried : \override Staff.VerticalAxisGroup #'minimum-Y-extent = #'(-2 . 2) but this make appear the key (which I don't want) and a staff of length one pixel.
