## Question:

Is there a way to change how the score title appears based on whether it’s on an odd or even page?

### Given:

```
% --- paper.ily
\paper {
  scoreTitleMarkup = \markup \column {
    \fill-line {
      \box \fromproperty #'header:order
      \bold \fromproperty #'header:title
      \null
    }
    \fill-line {
      \null
      \italic \fromproperty #'header:author
    }
  }
}
```

```
% --- score.ily
\score {
  <<
    \new Staff \music
  >>
  \header {
    title = \title
    order = \order
    author = \author
  }
}
```

```
% --- compile.ly
title = "Good Afternoon"
order = "1"
author = "Santa"
music = {
  % ...
}
\include "./score.ily"

title = "Good Evening"
order = "2"
author = "Elves"
music = {
  % ...
}
\include "./score.ily"

title = "Good Night"
order = "3"
author = "Truman"
music = {
  % ...
}
\include "./score.ily"
```

### Result:

[![two sheet music pages side-by-side, all score titles look the same][1]][1]

### Contrived Example:

(Notice the `order` and `author` are on reversed sides on the right-hand page.)
