where it is inserted.
+Within a score, automatic line breaking is prevented within music

+inhibiting automatic line breaks may cause music to run over the
+right margin if it cannot all be contained within one line.

+Automatic line breaks (but not page breaks) may be enabled at single
+bar lines by using @code{\once \autoLineBreaksOn} at a bar line.

Explicit @code{\breaks} evenly divide the music into six measures per

measure, the shortest duration is determined. The most common shortest

that this shortest duration should always be equal to or shorter than
-an 8th note. The shortest duration is printed when you run
