single-tone recitative to a fixed melodic gesture. In these cases,
one can use either @code{\hide Stem} or
@code{\override Stem.length = #0} instead, and restore the stem
-when needed with the corresponding @code{\once \override Stem.transparent = ##f} (see example below). When using stems that
-carry flags, make sure to set @code{\hide Flag} as well.

@b{Timing.} For unmetered chant, there are several alternatives.
@unnumberedsubsubsec Removing the stencil
@cindex stencil, removing
+@funindex \omit
Every layout object has a stencil property. By default this is set
to the specific function which draws that object. If this property
will not be drawn. The default action can be recovered with
@code{\revert}.
+@lilypond[quote,verbatim,relative=1]
+a1 a
+\override Score.BarLine.stencil = ##f
+a a
+\revert Score.BarLine.stencil
+a a a
+@end lilypond
+
+This rather common operation has a shortcut @code{\omit}:

@lilypond[quote,verbatim,relative=1]

\omit Score.BarLine
@unnumberedsubsubsec Making objects transparent
@cindex transparent, making objects
+@funindex \hide
Every layout object has a transparent property which by default is
set to @code{#f}. If set to @code{#t} the object still occupies
space but is made invisible.
