### 3.1.2 Multiple scores in a book

A document may contain multiple pieces of music and text. Examples of these are an etude book, or an orchestral part with multiple movements. Each movement is entered with a `\score` block,

>     \score {
>       …music…
>     }

and texts are entered with a `\markup` block,

>     \markup {
>       …text…
>     }

All the movements and texts which appear in the same ‘`.ly`’ file will normally be typeset in the form of a single output file.

>     \score {
>       …
>     }
>     \markup {
>       …
>     }
>     \score {
>       …
>     }

One important exception is within lilypond-book documents, where you explicitly have to add a `\book` block, otherwise only the first `\score` or `\markup` will appear in the output.

The header for each piece of music can be put inside the `\score` block. The `piece` name from the header will be printed before each movement. The title for the entire book can be put inside the `\book`, but if it is not present, the `\header` which is at the top of the file is inserted.

>     \header {
>       title = "Eight miniatures"
>       composer = "Igor Stravinsky"
>     }
>     \score {
>       …
>       \header { piece = "Romanze" }
>     }
>     \markup {
>        …text of second verse…
>     }
>     \markup {
>        …text of third verse…
>     }
>     \score {
>       …
>       \header { piece = "Menuetto" }
>     }

Pieces of music may be grouped into book parts using `\bookpart` blocks. Book parts are separated by a page break, and can start with a title, like the book itself, by specifying a `\header` block.

>     \bookpart {
>       \header {
>         title = "Book title"
>         subtitle = "First part"
>       }
>       \score { … }
>       …
>     }
>     \bookpart {
>       \header {
>         subtitle = "Second part"
>       }
>       \score { … }
>       …
>     }
