Hi,
considering the statement by Gould below and my personal findings,
I would like to see the following change to the ottavation bracket be
added to LilyPond like proposed in this thread:
http://lists.gnu.org/archive/html/lilypond-user/2014-02/msg00321.html
and now updated in this mail.
Could this be added to the issues as a wish or enhancement (it is even a
bit ugly).
Cheers,
Joram
Here is my wish including examples:
What does E. Gould say ...
Page 28:
The octave sign is written in italic, the numeral '8' is 1 1/2
stave-paces high. The optional 'va' is placed flush with the top of
_ottava sopra_ (_8^va_), flush with the base of _ottava bassa_ (_8va_).
Indicate the extent of the transposition with a line of dashes
(hereafter called a dotted line). The line extends from the top edge
of the _8_ for _8 sopra_ and the base of the _8_ for _8 bassa_, and
runs parallel to the stave.
And those 8s look bold to me.
Brian Barker
This has something in common with the current situation, but these
points are different:
- there should be super/subscript for va etc.
- it should be bold
- the lines should be at the top edge/base and not in the middle
Here is my incomplete suggestion with some comments:
Text positioning:
- \super does not look good
- \raise depends on the staff size (not on the font size)
- therefore \translate-scaled
- the value is a compromise for 8 and 15 which look slightly different
- should we add text for a third octave to LP? ±3 (i.e. 22va and 22vb)
(this is easy in scm/define-music-callbacks.scm)
or a general text calculated from the octavation:
|octavation|*7 + 1 and va if octavation > 0, vb if octavation < 0
Lines
- The lines are unchanged but they should go to the top line or base
line respectively.
- The right edge would look better if it was a solid vertical line
(without a dash gap)
- I have seen more dotted than dashed lines, but that’s debatable.
This snippet shows what I propose as default. If accepted, the markups
would have to be translated to scheme:
