the property is @code{font-shape} and the value is
@code{italic}. As before, we'll omit the context.
-As an aside, although it is an important one, note that because the
-values of @code{font-shape} are symbols they must be introduced with a
-single apostrophe, @code{'}. That is why apostrophes are needed
-before @code{thickness} in the earlier example and @code{font-shape}.
-These are both symbols too. Symbols are then read internally by
-LilyPond. Some of them are the names of properties, like
-@code{thickness} or @code{font-shape}, others are used as values that
-can be given to properties, like @code{italic}. Note the distinction
-from arbitrary text strings, which would appear as @code{"a text

-In the case of lyrics, if you try specifying the context in the

-a newline or a digit. All other characters are included
-as part of the syllable. For this reason a space or newline
-must appear before the terminating @code{@}} to prevent it being
-included as part of the final syllable. Similarly,
-spaces must be inserted before and after the
-period or dot, @q{.}, separating the context name from the
-object name, as otherwise the two names are run together and
-the interpreter cannot recognize them. So the command should be:

@cindex beams, controlling manually
-The @code{positions} property allows the position and slope of
-tuplets, slurs, phrasing slurs and beams to be controlled manually.
-Here's an example which has an ugly phrasing slur due to its trying to
-avoid the slur on the acciaccatura.
+The @code{positions} property allows the vertical position and hence
+the slope of tuplets, slurs, phrasing slurs and beams to be controlled
+manually.
-@lilypond[quote,verbatim,fragment,ragged-right,relative=1]
-r4 \acciaccatura e8\( d8 c~ c d c d\)
-@end lilypond
+Here's an example in which the phrasing slur and slur collide:
-@noindent
-We could simply move the phrasing slur above the notes, and this
-would be the preferred solution:
-
-@lilypond[quote,verbatim,fragment,ragged-right,relative=1]
-r4
-\phrasingSlurUp
-\acciaccatura e8\( d8 c~ c d c d\)
+@lilypond[quote,verbatim,ragged-right]
+\relative { a'8 \( ( a'16 ) a \) }
@end lilypond
-@noindent
-But if there were some reason why this could not be done the
-other alternative would be to move the left end of the phrasing
-slur down a little using the @code{positions} property. This
-also resolves the rather nasty shape.
-
@cindex PhrasingSlur, example of overriding
@cindex positions property, example
-@lilypond[quote,verbatim,fragment,ragged-right,relative=1]
-r4
-\once \override PhrasingSlur.positions = #'(-4 . -3)
-\acciaccatura e8\( d8 c~ c d c d\)
+@noindent
+One possibility would be to move the two ends of the phrasing slur
+higher. We can try setting the left end to 2.5 staff-spaces above the
+centre line and the right end to 4.5 above, and LilyPond will
+select the phrasing slur from the candidates it has found with its
+end points closest to these:
+
+@lilypond[quote,verbatim,fragment,ragged-right]
+\once \override PhrasingSlur.positions = #'(2.5 . 4.5)
+a'8 \( ( a''16 ) a'' \)
@end lilypond
+This is an improvement, but why not lower the right end of the slur
+a little? If you try it you'll find it can't be done in this way.
+That's because there are no candidate slurs lower than the one
+already selected, and in this case the @code{positions} property has
+no effect. However, ties, slurs and phrasing slurs @emph{can} be
+positioned and shaped very precisely when necessary. To learn how to
+do this, see @ruser{Modifying ties and slurs}.
+
Here's a further example. We see that the beams
collide with the ties:
{
\time 4/2
<<
- { c'1 ~ c'2. e'8 f' }
+ { c'1 ~ 2. e'8 f' }
\\
{ e''8 e'' e'' e'' e'' e'' e'' e'' f''2 g'' }
>>
<<
- { c'1 ~ c'2. e'8 f' }
+ { c'1 ~ 2. e'8 f' }
\\
{ e''8 e'' e'' e'' e'' e'' e'' e'' f''2 g'' }
>>
{
\time 4/2
<<
- { c'1 ~ c'2. e'8 f' }
+ { c'1 ~ 2. e'8 f' }
\\
{
\override Beam.positions = #'(-1 . -1)
}
>>
<<
- { c'1 ~ c'2. e'8 f' }
+ { c'1 ~ 2. e'8 f' }
\\
{ e''8 e'' e'' e'' e'' e'' e'' e'' f''2 g'' }
>>
the second measure of eighth notes, but not to any of the beams in the
second voice.

+@cindex tweak, generated from override
+Now for @emph{overriding} the transparency of a graphical object,
+we could have used the shorthand @code{\hide} as explained above.
+Tweaking is a different operation, affecting only properties
+generated from a single music expression. It turns out that we
+can convert overrides into tweaks using @code{\single}, making it
+possible to rewrite the above example as
+
+@lilypond[quote,fragment,relative=2,verbatim]
+<<
+ {
+ \single \hide Stem
+ \single \hide Flag
+ \tweak Stem.length #8
+ b8~ 8\noBeam
+ }
+\\
+ { b8[ g] }
+>>
+@end lilypond
+
+In this particular case, the difference to @code{\once \hide} is
+not apparent. It is important when there are several objects at
+the same point in musical time (like noteheads in a chord). In
+that case, @code{\once} will affect all of those objects while
+@code{\single} will only affect a single one, the one generated by
+the immediately following music expression.
