\paper variables for line breaking
-
max-systems-per-page -
The maximum number of systems that will be placed on a page. This is currently supported only by the
ly:optimal-breakingalgorithm. Default: unset. -
min-systems-per-page -
The minimum number of systems that will be placed on a page. This may cause pages to be overfilled if it is made too large. This is currently supported only by the
ly:optimal-breakingalgorithm. Default: unset. -
systems-per-page -
The number of systems that should be placed on each page. This is currently supported only by the
ly:optimal-breakingalgorithm. Default: unset. -
system-count -
The number of systems to be used for a score. Default: unset. This variable can also be set in a
\layoutblock.

\paper variables for page breaking
Default values not listed here are defined in ‘ly/paper-defaults-init.ly’
-
page-breaking -
The page-breaking algorithm to use. Choices are
ly:minimal-breaking,ly:page-turn-breaking,ly:one-page-breaking,ly:one-line-breaking,ly:one-line-auto-height-breaking, andly:optimal-breaking(the default). -
page-breaking-system-system-spacing -
Tricks the page breaker into thinking that
system-system-spacingis set to something different than it really is. For example, ifpage-breaking-system-system-spacing.paddingis set to something substantially larger thansystem-system-spacing.padding, then the page-breaker will put fewer systems on each page. Default: unset. -
page-count -
The number of pages to be used for a score, unset by default.
The following variables are effective only when page-breaking
is set to ly:page-turn-breaking. Page breaks are then chosen
to minimize the number of page turns. Since page turns are required
on moving from an odd-numbered page to an even-numbered one, a
layout in which the last page is odd-numbered will usually be
favoured. Places where page turns are preferred can be indicated
manually by inserting \allowPageTurn or automatically by
including the Page_turn_engraver (see Optimal page turning).
If there are insufficient choices available for making suitable page turns, LilyPond may insert a blank page either within a score, between scores (if there are two or more scores), or by ending a score on an even-numbered page. The values of the following three variables may be increased to make these actions less likely.
The values are penalties, i.e., the higher the value the less likely will be the associated action relative to other choices.
-
blank-page-penalty -
The penalty for having a blank page in the middle of a score. If
blank-page-penaltyis large andly:page-turn-breakingis selected, then LilyPond will be less likely to insert a page in the middle of a score. Instead, it will space out the music further to fill the blank page and the following one. Default: 5. -
blank-last-page-penalty -
The penalty for ending the score on an even-numbered page. If
blank-last-page-penaltyis large andly:page-turn-breakingis selected, then LilyPond will be less likely to produce a score in which the last page is even-numbered. Instead, it will adjust the spacing in order to use one page more or one page less. Default: 0. -
blank-after-score-page-penalty -
The penalty for having a blank page after the end of one score and before the next. By default, this is smaller than
blank-page-penalty, so that blank pages after scores are inserted in preference to blank pages within a score. Default: 2.

\paper variables for page numbering
Default values not listed here are defined in ‘ly/paper-defaults-init.ly’
-
auto-first-page-number -
The page breaking algorithm is affected by the first page number being odd or even. If set to true, the page breaking algorithm will decide whether to start with an odd or even number. This will result in the first page number remaining as is or being increased by one. Default:
#f. -
first-page-number -
The value of the page number on the first page.
-
print-first-page-number -
If set to true, a page number is printed on the first page.
-
print-page-number -
If set to false, page numbers are not printed.
-
page-number-type -
The type of numerals used for page numbers. Choices include
roman-lower,roman-upperandarabic. Default:'arabic.

Known issues and warnings
Odd page numbers are always on the right. If you want the music to start on page 1 there must be a blank page on the back of the cover page so that page 1 is on the right hand side.

Miscellaneous \paper variables
-
page-spacing-weight -
The relative importance of page (vertical) spacing and line (horizontal) spacing. High values will make page spacing more important. Default:
10. -
print-all-headers -
If set to true, this will print all headers for each
\scorein the output. Normally only thepieceandopusheader variables are printed. Default:#f. -
system-separator-markup -
A markup object that is inserted between systems, often used for orchestral scores. Default: unset. The
\slashSeparatormarkup, defined in ‘ly/titling-init.ly’, is provided as a sensible default, for example:#(set-default-paper-size "a8") \book { \paper { system-separator-markup = \slashSeparator } \header { tagline = ##f } \score { \relative { c''1 \break c1 \break c1 } } } -
footnote-separator-markup -
A markup object that is inserted above the footnote texts at the bottom of the page. Default: a centered horizontal line, defined in ‘ly/paper-defaults-init.ly’.

Known issues and warnings
The default page header puts the page number and the instrument
field from the \header block on a line.
