ossia vertical spacing

[eluze]

hi

assuming you are using ungrouped staves you can use something like

\layout {
  \context {
    \Staff
    \override VerticalAxisGroup #'default-staff-staff-spacing = #'(
      (basic-distance . 0)
      (minimum-distance . 0)
      (padding . -2)
      (stretchability . 90)
    )
  }
}

and play around with the numbers!

this is discribed in the chapter you mention: "Spacing of ungrouped staves"
