What makes you believe that your code is a Scheme file? The given
example uses
```
\override foo.bar = #(...some Scheme code...)
```
This is standard LilyPond syntax, which wraps Scheme code into a
`#(...)` construction. Consequently, you can use `\include` in the
normal way.
There also exists a `#{...#}` contruction, which allows to wrap
LilyPond code within Scheme code, for example
```
\override foo.bar = #(
... some Scheme code ...
#{ ... some LilyPond code ... #}
... some Scheme code ...
)
```
This often makes it very simple to write Scheme extensions.
BTW, LilyPond actually contains real Scheme files, having the file
name extension `.scm` (such files can be found in the `scm`
subdirectory of LilyPond's data directory tree). They are loaded at
start-up with a different mechanism, and 'normal' users don't need to
know the exact details how it is done.
