These must always be present in exactly this form. This is the

Here we use the constants @code{DOWN} and @code{UP}.
-These have the values @code{-1} and @code{+1} respectively, and
+These have the values @w{@code{-1}} and @code{+1} respectively, and
these numerical values may be used instead. The value @code{0}
may also be used in some cases. It is simply treated as meaning
@code{UP} for stems, but for some objects it means @q{center}.
@noindent
If the fingering seems a little crowded the @code{font-size}
could be reduced. The default value can be seen from the
-@code{Fingering} object in the IR to be @code{-5}, so let's
-try @code{-7}:

the @code{self-alignment-interface}. In general these are objects
that contain text. The values are @code{LEFT}, @code{RIGHT}
or @code{CENTER}. Alternatively, a numerical value between
-@code{-1} and @code{+1} may be specified, where @code{-1} is
+@w{@code{-1}} and @code{+1} may be specified, where @w{@code{-1}} is
left-aligned, @code{+1} is right-aligned, and numbers in between
move the text progressively from left-aligned to right-aligned.
Numerical values greater than @code{1} may be specified to move

in the value corresponds to a movement of half the text's length.
the rest is in voice two. The default in @code{\voiceTwo} (i.e. in
the second voice of a @code{<<@{...@} \\ @{...@}>>} construct) is that
@code{staff-position} is set to -4 for MultiMeasureRest, so we need to

-Here's a further example taken from the opening of the left-hand
-staff of Chopin's Prelude Op 28 No. 2. We see that the beam

This can be resolved by manually moving both ends of the beam
