Hi Ben,

How about:

half-brace = \markup\concat {

Hi Ben,

How would you suggest I go about creating the bracket markings that separate big sections, like in a piece with two orchestras or similar?

Create a custom StaffGroup context.

ideally I'd prefer the circle symbol in the bracket to always be centered alongside the staff group

The InstrumentName is center-able — override it.  =)

Hope that helps!
Kieren.

Kieren,

I just came across this link!

It helps me visually see how to approach this better. But I'm confused how to create a custom 'bracket' rather...

I'll keep at it. If you have any hints, I welcome them. :) Thank you!

Pierre,

Wow this is incredibly helpful. I see now how the overrides work beautifully with your custom group! How do you recommend I go about creating a second bracket though, for the other orchestra? (1 and 2, instead of 1 and 1 - see attached). I don't understand the best way to duplicate the context in this case.
