Hi

​ all​

,

​

Is there a simpler way to extend an ottava bracket a bit to the left?

In the snippet below, the first bar is the default p

​ lacement with no tweaks​

. The second bar achieves what I want by adapting the example "Modifying the Ottava spanner slope"

​ from the documentation.​ Is it an overkill though? Is there a shorter way to access the same parameter?

I tried something like \override Staff.OttavaBracket.shorten-pair = #'(-5 . 0) but found this affects only the line, not the text "8va".

Thanks in advance for any help!

This is a little bit funny, but it works almost equally well for the case you show (and with fewer lines of code):

{
  \time 6/8
  <e' g' c''>8\arpeggio\pp\<[
  <as' cs'' fs''>\arpeggio
  <ef'' af'' c'''>\arpeggio
  \ottava 1
  \override Staff.OttavaBracket.shorten-pair = #'(-6 . -0.6)
  \set Staff.ottavation = #"8va          "
  <as'' cs''' fs'''>\arpeggio
  <e''' g''' c''''>\arpeggio
  <b''' e'''' g'''' b''''>]\mf\arpeggio \ottava 0
}

I found that you adjust the number of spaces after "8va" and then tweak the first value of "shorten-pair" to match.
