4.3.1 Line breaking
Line breaks are normally determined automatically. They are chosen
so that lines look neither cramped nor loose, and consecutive
lines have similar density. Occasionally you might want to
override the automatic breaks; you can do this by specifying
\break
. This will force a line break at this point. However,
line breaks can only occur at the end of ‘complete’ bars, i.e.,
where there are no notes or tuplets left ‘hanging’ over the bar
line. If you want to have a line break where there is no bar line,
you can force an invisible bar line by entering \bar ""
,
although again there must be no notes left hanging over in any of
the staves at this point, or it will be ignored.
The opposite command, \noBreak
, forbids a line break at the
bar line where it is inserted.
The most basic settings influencing line spacing are indent
and line-width
. They are set in the \layout
block.
They control the indentation of the first line of music, and the
lengths of the lines.
If ragged-right
is set to true in the \layout
block,
then systems end at their natural horizontal length, instead of
being spread horizontally to fill the whole line. This is useful
for short fragments, and for checking how tight the natural
spacing is.
The option ragged-last
is similar to ragged-right
,
but affects only the last line of the piece.
\layout { indent = #0 line-width = #150 ragged-last = ##t }
For line breaks at regular intervals use \break
separated by
skips and repeated with \repeat
. For example, this would
cause the following 28 measures (assuming 4/4 time) to be broken
every 4 measures, and only there:
<< \repeat unfold 7 { s1 \noBreak s1 \noBreak s1 \noBreak s1 \break } the real music >>
A linebreaking configuration can be saved as a .ly
file
automatically. This allows vertical alignments to be stretched to
fit pages in a second formatting run. This is fairly new and
complicated. More details are available in
Spacing.

Known issues and warnings
Line breaks can only occur if there is a ‘proper’ bar line. A note which is hanging over a bar line is not proper, such as
c4 c2 << c2 {s4 \break } >> % this does nothing c2 c4 | % a break here would work c4 c2 c4 ~ \break % as does this break c4 c2 c4
This can be avoided by removing the Forbid_line_break_engraver
.
Note that manually forced line breaks have to be added in parallel
with the music.
\new Voice \with { \remove Forbid_line_break_engraver } { c4 c2 << c2 {s4 \break } >> % now the break is allowed c2 c4 }
Similarly, line breaks are normally forbidden when beams cross bar
lines. This behavior can be changed by setting
\override Beam #'breakable = ##t
.
