lilypond-usage: Music runs off the page

 
 Music runs off the page
 -----------------------
 
 Music running off the page over the right margin or appearing unduly
 compressed is almost always due to entering an incorrect duration on a
 note, causing the final note in a measure to extend over the bar line.
 It is not invalid if the final note in a measure does not end on the
 automatically entered bar line, as the note is simply assumed to carry
 over into the next measure.  But if a long sequence of such carry-over
 measures occurs the music can appear compressed or may flow off the page
 because automatic line breaks can be inserted only at the end of
 complete measures, i.e., where all notes end before or at the end of the
 measure.
 
           Note: An incorrect duration can cause line breaks to be
           inhibited, leading to a line of highly compressed music or
           music which flows off the page.
 
    The incorrect duration can be found easily if bar checks are used,
 see (lilypond-notation)Bar and bar number checks.
 
    If you actually intend to have a series of such carry-over measures
 you will need to insert an invisible bar line where you want the line to
 break.  For details, see (lilypond-notation)Bar lines.
