+Octave checks make octave errors easier to correct: a note may be
+followed by @code{=}@var{quotes} which indicates what its absolute
+octave should be. In the following example,
+@example
+ \relative c'' @{ c='' b=' d,='' @}
+@end example
+
+@noindent
+the @code{d} will generate a warning, because a @code{d''} is
+expected, but a @code{d'} is found. In the output, the octave is
+corrected this and the following notes.
+
+There is also a syntax that is separate from the notes.
@example
\octave @var{pitch}
@end example
For linebreaks at regular intervals use @code{\break} separated by
skips and repeated with @code{\repeat}:
@example
-<< \repeat unfold 7 @{ s1 * 4 \break @}
+<< \repeat unfold 7 @{
+ s1 \noBreak s1 \noBreak
+ s1 \noBreak s1 \break @}
@emph{the real music}
>>
@end example
@noindent
This makes the following 28 measures (assuming 4/4 time) be broken every
-4 measures.
+4 measures, and only there.
