Hi Kieren,

I've spend most of the day on this topic, starting even before you
wrote this mail.
Let me ensure you, my table has some nice bite marks more ...

All this predefining markups down/above/parenthesized is way too
tedious and error-prone and would need to be done for
double-ottavation as well ...
And \raise will break whenever you want to use another \fontsize ...

I tried a general approach.

Though, what has driven me crazy is the impossibility to set
OttavaBracket.text sufficiently.
None of the below works for _all_ OttavaBrackets:

{
  \override Staff.OttavaBracket.text = "foo"
  \ottava #1 c''4 4 4 4  4 4 \ottava #0 4 4  \break
  \ottava #2 c''4 4 4 4  4 4 \ottava #0 4 4  \break
  \ottava #-1 c4 4 4 4   4 4 \ottava #0 4 4 \break
  \ottava #-2 c'4 4 4 4  4 4 \ottava #0 4 4 \break
}

{
  \override Staff.OttavaBracket.after-line-breaking =
    #(lambda (grob) (ly:grob-set-property! grob 'text "foo"))
  \ottava #1 c''4 4 4 4  4 4 \ottava #0 4 4  \break
  \ottava #2 c''4 4 4 4  4 4 \ottava #0 4 4  \break
  \ottava #-1 c4 4 4 4   4 4 \ottava #0 4 4 \break
  \ottava #-2 c'4 4 4 4  4 4 \ottava #0 4 4 \break
}

If you do it 'before-line-breaking it works, yes, but can't be changed
'after-line-breaking anymore ...

No idea what's happening and why.

Thus I did some ugly trickery with 'before-line-breaking.

Please look at the attached png and test the attached code.
Tell me what isn't sufficient.

Cheers,
  Harm
