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

21.2.2 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
See Default layout of bookpart and score titles for the
placement of titles when using the default values of these
\markup
variables.
The default setting for scoreTitleMarkup
defined in
ly/titling-init.ly is as follows.
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 } }![]()
The next example redefines scoreTitleMarkup
so that the
piece
text field is centered, using 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 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 } } }![]()

21.2.3 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 one or more 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 assigning #f
.
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 = ##f evenHeaderMarkup = ##f 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? 7 \should-print-page-number
Print the number of the current page? \should-print-all-headers
Is print-all-headers
true?

\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.
