No they will not. If you do use \mark, it creates a RehearsalMark
object, that lives in the Score context, and not in the Staff context:
in other words, even if the staff temporarily disappears the
RehearsalMark will still be printed anyway.

Therefore, you don't have to add any \mark to your flute staff. The
piccolo is enough.

Let me explain it another way: you have to put all the \mark commands
in only one variable (for example, the \marks variable like you did).
You can remove all \mark commands in the other variables (the piccolo,
the flute etc). The marks will automatically be added to the _Score_
(not just to the _Staff_ )

That's a bit more complicated. To print marks above other staves than
the topmost staff, there is no ready-to-use solution in LilyPond.

Two solutions exist:

- you can add the mark engraver to your violin 1 staff:

 \new Staff \with {
      \consists "Mark_engraver"
    } { << \vI \marks >> }

However, this kind of marks will disappear when the violins are not playing.

- to avoid this, you can also create a special context, in the \layout
block. This solution is more complicated, but this is the one I use:

\layout {
  \context {
    \type "Engraver_group"
    \name "MarkLine"
    \consists "Output_property_engraver"
    \consists "Axis_group_engraver"
    \consists "Mark_engraver"
    \consists "Metronome_mark_engraver"
    \override VerticalAxisGroup #'minimum-Y-extent = #'(-2 . 2 )
  }
  \context {
    \Score
    \remove "Mark_engraver"
    \remove "Metronome_mark_engraver"
    \accepts "MarkLine"
  }
}

And then, you will have to create a \new MarkLine at the right place,
and put the \marks variable inside it.

\score {
  <<
  \new MarkLine { \marks } % here...
  \new Staff { \pic }
  \new Staff { \fl }
  ...
  \new MarkLine { \marks }  % and here!
  \new Staff { \vI }
  \new Staff { \vII }
  ...
  >>
}

You should probably add all the marks in it, just not the \default marks.

Yes, that is the second method I explained above (except that I call
it the MarkLine context instead of the Dynamics context). This context
will not disappear, and the marks will always be printed.

Good luck,
