Unmetered music: An alternative to \cadenzaOn: Difference between revisions

VisualWikitext
Created page with "If your music is unmetered, you might use <code>\cadenzaOn</code>. But <code>\cadenzaOn</code> will disable automatic measure demarcation, and when it is applied, the <code>\bar</code> command will ''not'' start a new measure. <u>If you want the features that come with measure demarcation</u> (e.g., resetting '''accidentals''', automatic '''bar numbering''', automatic '''beaming'''), the following approach may be useful. It combines <code>\omit TimeSignature</code> with..."
 
I changed the music example.
