No, there's no need for a special context object,

two Dynamic contexts will do.  The key things to

remember are that the flexible spacing variables

act on the space between the context in which they

are applied and the one below, and that Dynamic

contexts are of 'non-staff' type.  So you need to

change the nonstaff-nonstaff-spacing variables of

the uppermost Dynamic context.  Setting basic-distance

is probably sufficient:

 

\version "2.19.16"

 

\score {
  <<
    \new PianoStaff <<
      \new Staff { a' a' a' a' }
      \new Staff { \clef bass a a a a }
    >>
    \new Dynamics
    \with {
      \override VerticalAxisGroup.nonstaff-nonstaff-spacing.basic-distance = #4
    }
    { s\p s s\f s }
    \new Dynamics
    { s\sustainOn s s s\sustainOff }
  >>
}

 

If you want to understand this further, the section

to read is

and the subsection
