+
+The within-system vertical spacing mechanisms are controlled by
+two sets of grob properties. The first set is associated with the
+@code{VerticalAxisGroup} grob, which is created by all staves and
+non-staff lines. The second set is associated with the
+@code{StaffGrouper} grob, which can be created by staff-groups,
+but only if explicitly called. These properties are described
+individually at the end of this section.
+
+Except for the @code{staff-affinity} property (of the
+@code{VerticalAxisGroup} grob), each of these grob properties is
+stored as an alist (association list), and each uses the same
+alist structure as the @code{\paper} spacing variables discussed
+in @ref{Flexible vertical dimensions}.
+
+The @emph{reference point} for a staff is the vertical center of
+its @code{StaffSymbol} (i.e. the middle line if @code{line-count}
+is odd; the middle space if @code{line-count} is even).
+
+The reference points for individual non-staff lines are given in

-@item
-@var{minimum-distance} provides a lower bound on the final distance
-between the center line of one staff to the center line of the next
-staff. That is, if a page has many systems and needs to be compressed,
-the distance from this staff to the next will never be compressed to
-less than @var{minimum-distance}.
+Default overrides for specific types of non-staff lines can be
+found in the relevant context definitions in
+@file{ly/engraver-init.ly}.
-@item
-@var{padding} is the amount of whitespace that must be present between
-the bottom of one staff and the top of the next. It differs from
-@var{minimum-distance} in that the effect of @var{padding} depends on
-the height of objects in the staff. For example, @var{padding} is more
-likely to come into effect for staves with notes that are far below the
-staff.
-@item
-@var{stretchability} controls the stretchable space's propensity to
-stretch when the system is stretched. Large values will cause a
-system to stretch more, while a value of zero will prevent the
-space from stretching at all. If unset, @var{stretchability}
-defaults to @code{space - minimum-distance}.
+@subsubheading Properties of the @code{VerticalAxisGroup} grob
+
+@code{VerticalAxisGroup} properties are typically adjusted with an
+@code{\override} at the @code{Staff} level (or equivalent).
+
+@table @code
+@item next-staff-spacing
+The distance between the current staff and the staff just below it
+in the same system, even if one or more non-staff lines (such as
+@code{Lyrics}) are placed between the two staves. Does not apply
+to the bottom staff of a system. For a grouped staff, if
+@code{next-staff-spacing} is set, it will be used instead of the
+relevant @code{StaffGrouper} property
+(@code{between-staff-spacing} or @code{after-last-staff-spacing}).
+If unset, the @code{default-next-staff-spacing} property is used,
+unless the staff is part of a staff-group and the appropriate
+@code{StaffGrouper} property is set.
+
+@item default-next-staff-spacing
+The value to use for @code{next-staff-spacing} when it is unset,
+for ungrouped staves and for grouped staves that do not have the
+relevant @code{StaffGrouper} property set
+(@code{between-staff-spacing} or @code{after-last-staff-spacing}).
+
+@item staff-affinity
+The direction of the staff to use for spacing the current
+non-staff line. Choices are @code{UP}, @code{DOWN}, and
+@code{CENTER}. If @code{CENTER}, the non-staff line will be
+placed equidistant between the two nearest staves on either side,
+unless collisions or other spacing constraints prevent this.
+Adjacent non-staff lines should have non-increasing
+@code{staff-affinity} from top to bottom, e.g. a non-staff line
+set to @code{UP} should not immediately follow one that is set to
+@code{DOWN}. Non-staff lines at the top of a system should use
+@code{DOWN}; those at the bottom should use @code{UP}. Setting
+@code{staff-affinity} to @code{#f} will cause a non-staff line to
+be treated as a staff. Conversely, setting @code{staff-affinity}
+(to @code{UP}, @code{DOWN}, or @code{CENTER}) for a staff will
+cause it to be treated as a non-staff line.
+
+@c TODO: verify last clause below ("even if other...")
+
+@item inter-staff-spacing
+The distance between the current non-staff line and the nearest
+staff in the direction of @code{staff-affinity}, if there are no
+non-staff lines between the two, and @code{staff-affinity} is
+either @code{UP} or @code{DOWN}. If @code{staff-affinity} is
+@code{CENTER}, then @code{inter-staff-spacing} is used for the
+nearest staves on @emph{both} sides, even if other non-staff lines
+appear between the current one and either of the staves.
+
+@item inter-loose-line-spacing
+The distance between the current non-staff line and the next
+non-staff line in the direction of @code{staff-affinity}, if both
+are on the same side of the reference staff, and
+@code{staff-affinity} is either @code{UP} or @code{DOWN}.
+
+@item non-affinity-spacing
+The distance between the current non-staff line and the staff in
+the opposite direction from @code{staff-affinity}, if there are no
+other non-staff lines between the two, and @code{staff-affinity}
+is either @code{UP} or @code{DOWN}. This can be used, for

-cause it to be treated like a non-staff.

-Adjacent non-staff lines should have non-increasing
-@var{staff-affinity} from top-to-bottom. For example, the behavior of

-A non-staff line at the bottom of a system should have
-@var{staff-affinity} set to @code{UP}. Similarly, a non-staff
-line at the top of a system should have @var{staff-affinity} set
-to @code{DOWN}.

-@subsection Vertical spacing between systems
-
-The mechanisms that control spacing between systems are similar to those
-that control spacing between staves within a system (see
-@ref{Vertical spacing inside a system}). The main difference is that
-the variables to control spacing between systems are set in the
-@code{\paper} block, rather than as grob properties. These paper block
-variables are @var{system-system-spacing},
-@var{score-system-spacing}, @var{markup-system-spacing},
-@var{score-markup-spacing}, @var{markup-markup-spacing},
-@var{top-system-spacing}, @var{top-markup-spacing} and
-@var{last-bottom-spacing}. Note that these variables ignore non-staff
-lines. For example, @var{system-system-spacing} controls the spacing
-from the middle staff line of the bottom staff from one system to
-the middle staff line of the top staff of the next system, whether
-or not there are lyrics below the upper system.
-See @ref{Flexible vertical dimensions} for a description of each
-of these variables.
-
-There are two more @code{\paper} block variables that affect vertical
-spacing: if @var{ragged-bottom} is set to @code{##t} then no pages will
-be stretched (which means that neither the space between systems nor the
-space within systems will be stretched). If @var{ragged-last-bottom}
-is set to @code{##t} then the last page will not be stretched.
