Hi Matt,

Actually, you can stick an override in the note entry of the music
itself if you want to.

In fact, there are three override locations. All three override
locations are equivalent:

1. In a \context block (which lives within the a \layout block)
2. In a \with block (which follows context instantiation immediately)
3. In the note entry of the actual music


1. Here's an override in a \context block, as before:

    \score {
      \relative c'' {
        c4\startGroup\startGroup
        c4\stopGroup
        c4\startGroup
        c4\stopGroup\stopGroup
      }
      \layout {
        \context {
          \Staff \consists "Horizontal_bracket_engraver"
          \override HorizontalBracket #'direction = #up
    }}}


2. Here's an override in a \with block:

\score {
  \new Staff \with {
     \consists "Horizontal_bracket_engraver"
     \override HorizontalBracket #'direction = #up
   } {
     \relative c'' {
        c4\startGroup\startGroup
        c4\stopGroup
        c4\startGroup
        c4\stopGroup\stopGroup
      }
  }
}


3. And here's an override in the note entry of the music itself:

\score {
  \new Staff \with {
     \consists "Horizontal_bracket_engraver"
  } {
     \override Staff.HorizontalBracket #'direction = #up
     \relative c'' {
        c4\startGroup\startGroup
        c4\stopGroup
        c4\startGroup
        c4\stopGroup\stopGroup
      }
  }
}


Gurus, are there any other override locations? Or just these three?

Use whichever override location you prefer. (I prefer method #2 with a
\with block, because this leaves context settings with the context and
layout settings in \layout. Other users prefer other override
locations as a matter of style.)

No matter which override location you pick, you *must* first determine
the context of the grob you wish to override. In this case the
HorizontalBracket grob lives in the Staff context. You absolutely have
to determine this; otherwise you might write something like \override
Voice.HorizontalBracket #'direction = #up, which is absolutely correct
syntactically but will have no effect whatsoever because you've
misspecified the context.
