Custom text formatting for titles
Standard \markup commands can be used to customize any header,
footer and title text within the \header block.
\score { \header { piece = \markup { \fontsize #4 \bold "PRAELUDIUM I" } opus = \markup { \italic "BWV 846" } } { s1 } }

Custom layout for titles
\markup commands in the \header block are useful for
simple text formatting, but they do not allow precise control over the
placement of titles. To customize the placement of the text fields,
change either or both of the following \paper variables:
-
bookTitleMarkup -
scoreTitleMarkup
The placement of titles when using the default values of these
\markup variables is shown in the examples in
Default layout of bookpart and score titles.
The default settings for scoreTitleMarkup as defined in
‘ly/titling-init.ly’ are:
scoreTitleMarkup = \markup { \column {
\if \should-print-all-headers { \bookTitleMarkup \hspace #1 }
\fill-line {
\fromproperty #'header:piece
\fromproperty #'header:opus
}
}
}
This places the piece and opus text fields at opposite
ends of the same line:
\score { \header { piece = "PRAELUDIUM I" opus = "BWV 846" } { s1 } }
This example redefines scoreTitleMarkup so that the piece
text field is centered and in a large, bold font.
\book { \paper { indent = 0\mm scoreTitleMarkup = \markup { \fill-line { \null \fontsize #4 \bold \fromproperty #'header:piece \fromproperty #'header:opus } } } \header { tagline = ##f } \score { \header { piece = "PRAELUDIUM I" opus = "BWV 846" } { s1 } } }
Text fields not normally effective in score \header blocks
can be printed in the Score Title area if print-all-headers is
placed inside the \paper block. A disadvantage of using this
method is that text fields that are intended specifically for the
Bookpart Title area need to be manually suppressed in every
\score block. See Titles explained.
To avoid this, add the desired text field to the scoreTitleMarkup
definition. In the following example, the composer text field
(normally associated with bookTitleMarkup) is added to
scoreTitleMarkup, allowing each score to list a different
composer:
\book { \paper { indent = 0\mm scoreTitleMarkup = \markup { \fill-line { \null \fontsize #4 \bold \fromproperty #'header:piece \fromproperty #'header:composer } } } \header { tagline = ##f } \score { \header { piece = "MENUET" composer = "Christian Petzold" } { s1 } } \score { \header { piece = "RONDEAU" composer = "François Couperin" } { s1 } } }
It is also possible to create your own custom text fields, and refer to them in the markup definition.
\book { \paper { indent = 0\mm scoreTitleMarkup = \markup { \fill-line { \null \override #`(direction . ,UP) \dir-column { \center-align \fontsize #-1 \bold \fromproperty #'header:mycustomtext %% User-defined field \center-align \fontsize #4 \bold \fromproperty #'header:piece } \fromproperty #'header:opus } } } \header { tagline = ##f } \score { \header { piece = "FUGA I" mycustomtext = "A 4 VOCI" %% User-defined field opus = "BWV 846" } { s1 } } }

Custom layout for headers and footers
\markup commands in the \header block are useful for
simple text formatting, but they do not allow precise control over the
placement of headers and footers. To customize the placement of
the text fields, use either or both of the following \paper
variables:
-
oddHeaderMarkup -
evenHeaderMarkup -
oddFooterMarkup -
evenFooterMarkup
The \markup command \if can be used to add markup
conditionally to header and footer text defined within the
\paper block, using the following syntax within
\markup:
\if condition argument
The condition is tested each time the markup is interpreted. The
resulting markup is argument if the condition is true, but empty if false.
Typical conditions include tests for page numbers (first page, last page,
specific page, …). To test for the condition being false, replace
\if with \unless.
The following example centers page numbers at the bottom of every
page. First, the default settings for oddHeaderMarkup and
evenHeaderMarkup are removed by defining each as a null
markup. Then, oddFooterMarkup is redefined with the page
number centered. Finally, evenFooterMarkup is given the
same layout by defining it as \oddFooterMarkup:
\book { \paper { print-page-number = ##t print-first-page-number = ##t oddHeaderMarkup = \markup \null evenHeaderMarkup = \markup \null oddFooterMarkup = \markup { \fill-line { \if \should-print-page-number \fromproperty #'page:page-number-string } } evenFooterMarkup = \oddFooterMarkup } \score { \new Staff { s1 \break s1 \break s1 } } }
Here is a list of all predefined procedures available for use with
\if and \unless.
| Syntax | Condition tested |
|---|---|
\on-first-page | First page in the book? |
\on-last-page | Last page in the book? |
\on-first-page-of-part | First page in the book part? |
\on-last-page-of-part | Last page in the book part? |
\on-page n | On page number n? |
\single-page | Does the book fit on just one page? |
\should-print-page-numbers-global | Print page numbers in the book? 1 |
\should-print-page-number | Print the number of the current page? |
\should-print-all-headers | Is print-all-headers true? |

[1] \should-print-page-numbers-global can differ from
\should-print-page-number for the first page in the book,
depending on the print-first-page-number setting of the
\paper block.
