Re: ...and thy Staff, they comfort me

[Mats Bengtsson]

A number of different features were involved here, I'll try to describe
them one by one:

- The new context type Dynamics defined in the file was only allowed to
  be included in PianoStaff contexts. If you add an \accepts statement
  also in the definition of the Score context, LilyPond will allow also
  the two Dynamics contexts outside the PianoStaff to be handled
  correctly. (Don't ask me why they still appeared but in the wrong
  order). This should solve the ordering problem.

- Your \global contains objects that have a duration (the s8*6*10),
  which means that they have to appear within some kind of context.
  If no such context already exists, LilyPond will create one for you.

  If you comment out the line with \RemoveEmptyStaffContext in your
  original example, you will see that LilyPond creates an extra Staff
  context to be able to host your \global definition.
  I definitely recommend to include it in some existing Staff instead,
  for example the "mel" Staff.

- Why did you use additional Dynamics staves for the dynamics and pedal
  marks? Why not just include them within the existing staves?
  If you make sure to keep them in the same Voice context as the
  corresponding music, LilyPond will even make sure that they don't
  collide with notes with several ledger lines. If you want them
  typeset at a larger distance from the staves by default, just
  increase the padding property of DynamicLineSpanner and
  SustainPedalLineSpanner, respectively.

The resulting file could look something like:
