`avoid-scripts` (boolean)

  If set, a tuplet bracket avoids the scripts associated with the note heads it encompasses.

`avoid-slur` (symbol)

  Method of handling slur collisions. Choices are `inside`, `outside`, `around`, and `ignore`. `inside` adjusts the slur if needed to keep the grob inside the slur. `outside` moves the grob vertically to the outside of the slur. `around` moves the grob vertically to the outside of the slur only if there is a collision. `ignore` does not move either. In grobs whose notational significance depends on vertical position (such as accidentals, clefs, etc.), `outside` and `around` behave like `ignore`.

`axes` (list)

  List of axis numbers. In the case of alignment grobs, this should contain only one number.

  How much to shorten beamed stems, when their direction is forced. It is a list, since the value is different depending on the number of flags and beams.

`beaming` (pair)

  Pair of number lists. Each number list specifies which beams to make. `0` is the central beam, `1` is the next beam toward the note, etc. This information is used to determine how to connect the beaming patterns from stem to stem inside a beam.

  A pair of numbers. The first number specifies the default length of a beamlet that sticks out of the left hand side of this stem; the second number specifies the default length of the beamlet to the right.

`break-align-orders` (vector)

  This is a vector of 3 lists: `#(end-of-line unbroken start-of-line`). Each list contains break-align symbols that specify an order of breakable items (see break-alignment-interface).

  For example, this places time signatures before clefs:

  >     \override Score.BreakAlignment.break-align-orders =
  >       #(make-vector 3 '(left-edge
  >                         cue-end-clef

`extra-spacing-height` (pair of numbers)

  In the horizontal spacing problem, we increase the height of each item by this amount (by adding the ‚car‘ to the bottom of the item and adding the ‚cdr‘ to the top of the item). In order to make a grob infinitely high (to prevent the horizontal spacing problem from placing any other grobs above or below this grob), set this to `(-inf.0 . +inf.0)`.

`extra-spacing-width` (pair of numbers)

`nonstaff-nonstaff-spacing` (list)

  The spacing alist controlling the distance between the current non-staff line and the next non-staff line in the direction of `staff-affinity`, if both are on the same side of the related staff, and `staff-affinity` is either `UP` or `DOWN`. See `staff-staff-spacing` for a description of the alist structure.

`nonstaff-relatedstaff-spacing` (list)

  The spacing alist controlling the distance between the current non-staff line and the nearest staff in the direction of `staff-affinity`, if there are no non-staff lines between the two, and `staff-affinity` is either `UP` or `DOWN`. If `staff-affinity` is `CENTER`, then `nonstaff-relatedstaff-spacing` is used for the nearest staves on both sides, even if other non-staff lines appear between the current one and either of the staves. See `staff-staff-spacing` for a description of the alist structure.

`nonstaff-unrelatedstaff-spacing` (list)

  The spacing alist controlling the distance between the current non-staff line and the nearest staff in the opposite direction from `staff-affinity`, if there are no other non-staff lines between the two, and `staff-affinity` is either `UP` or `DOWN`. See `staff-staff-spacing` for a description of the alist structure.

`number-type` (symbol)

  Numbering style. Choices include `roman-lower`, `roman-upper` and `arabic`.

`output-attributes` (list)

  An alist of attributes for the grob, to be included in output files. When the SVG typesetting backend is used, the attributes are assigned to a group (<g>) containing all of the stencils that comprise a given grob. For example, `'((id . 123) (class . foo) (data-whatever . „bar“))` will produce `<g id=„123“ class=„foo“ data-whatever=„bar“> … </g>`. In the Postscript backend, where there is no way to group items, the setting of the output-attributes property will have no effect.

`outside-staff-horizontal-padding` (number)

  By default, an outside-staff-object can be placed so that is it very close to another grob horizontally. If this property is set, the outside-staff-object is raised so that it is not so close to its neighbor.

  One of four directives telling how outside staff objects should be placed.

  - `left-to-right-greedy` – Place each successive grob from left to right.
  - `left-to-right-polite` – Place a grob from left to right only if it does not potentially overlap with another grob that has been placed on a pass through a grob array. If there is overlap, do another pass to determine placement.
  - `right-to-left-greedy` – Same as `left-to-right-greedy`, but from right to left.
  - `right-to-left-polite` – Same as `left-to-right-polite`, but from right to left.
`outside-staff-priority` (number)

  Add this much extra space between objects that are next to each other.

`padding-pairs` (list)

  An alist mapping `(name . name)` to distances.

  Specify on which point of the parent the object is aligned. The value `-1` means aligned on parent’s left edge, `0` on center, and `1` right edge, in X direction. Other numerical values may also be specified - the unit is half the parent’s width. If unset, the value from `self-alignment-X` property will be used.

`parent-alignment-Y` (number)

  Like `parent-alignment-X` but for the Y axis.

`parenthesis-friends` (list)

  A list of Grob types, as symbols. When parentheses enclose a Grob that has ’parenthesis-friends, the parentheses widen to include any child Grobs with type among ’parenthesis-friends.

`parenthesized` (boolean)

  Parenthesize this grob.

`positions` (pair of numbers)

  Pair of staff coordinates `(start . end)`, where start and end are vertical positions in `staff-space` units of the current staff. For slurs, this value selects which slur candidate to use; if extreme positions are requested, the closest one is taken.

`prefer-dotted-right` (boolean)

  For note collisions, prefer to shift dotted up-note to the right, rather than shifting just the dot.

`protrusion` (number)

  In an arpeggio bracket, the length of the horizontal edges.

`rank-on-page` (number)

  0-based index of the system on a page.

`remove-layer` (index or symbol)

  When set as a positive integer, the `Keep_alive_together_engraver` removes all `VerticalAxisGroup` grobs with a `remove-layer` larger than the smallest retained `remove-layer`. Set to `#f` to make a layer independent of the `Keep_alive_together_engraver`. Set to `'()`, the layer does not participate in the layering decisions. The property can also be set as a symbol for common behaviors: `#'any` to keep the layer alive with any other layer in the group; `#'above` or `#'below` to keep the layer alive with the context immediately before or after it, respectively.

`replacement-alist` (list)

  Alist of strings. The key is a string of the pattern to be replaced. The value is a string of what should be displayed. Useful for ligatures.

  Number of degrees to rotate this object, and what point to rotate around. For example, `'(45 0 0)` rotates by 45 degrees around the center of this object.

`round-up-exceptions` (list)

  A list of pairs where car is the numerator and cdr the denominator of a moment. Each pair in this list means that the multi-measure rests of the corresponding length will be rounded up to the longer rest. See round-up-to-longer-rest.

`round-up-to-longer-rest` (boolean)

  Displays the longer multi-measure rest when the length of a measure is between two values of `usable-duration-logs`. For example, displays a breve instead of a whole in a 3/2 measure.

`rounded` (boolean)

  Decide whether lines should be drawn rounded or not.

`same-direction-correction` (number)

  Optical correction amount for stems that are placed in tight configurations. This amount is used for stems with the same direction to compensate for note head to stem distance.

`segno-kern` (number)

  The space between the two thin lines of the segno bar line symbol, expressed as a multiple of the default staff-line thickness (i.e. the visual output is not influenced by changes to `Staff.StaffSymbol.thickness`).

`self-alignment-X` (number)

  Specify alignment of an object. The value `-1` means left aligned, `0` centered, and `1` right-aligned in X direction. Other numerical values may also be specified - the unit is half the object width.

`self-alignment-Y` (number)

  Like `self-alignment-X` but for the Y axis.

`shape` (symbol)

  This setting determines what shape a grob has. Valid choices depend on the `stencil` callback reading this property.

`sharp-positions` (list)

  Sharps in key signatures are placed within the specified ranges of staff-positions. The general form is a list of pairs, with one pair for each type of clef, in order of the staff-position at which each clef places C: `(alto treble tenor soprano baritone mezzosoprano bass)`. If the list contains a single element it applies for all clefs. A single number in place of a pair sets accidentals within the octave ending at that staff-position.

`shorten-pair` (pair of numbers)

  The lengths to shorten on both sides a hairpin or text-spanner such as a pedal bracket. Positive values shorten the hairpin or text-spanner, while negative values lengthen it.

`shortest-starter-duration` (moment)

  The duration of the shortest note that starts here.

`side-axis` (number)

`skip-quanting` (boolean)

  Should beam quanting be skipped?

`skyline-horizontal-padding` (number)

  For determining the vertical distance between two staves, it is possible to have a configuration which would result in a tight interleaving of grobs from the top staff and the bottom staff. The larger this parameter is, the farther apart the staves are placed in such a configuration.

`skyline-vertical-padding` (number)

  The amount by which the left and right skylines of a column are padded vertically, beyond the `Y-extent`s and `extra-spacing-height`s of the constituent grobs in the column. Increase this to prevent interleaving of grobs from adjacent columns.

`slash-negative-kern` (number)

  The space to remove between slashes in percent repeat glyphs. Larger values bring the two elements closer together.

`slope` (number)

  The slope of this object.

`slur-padding` (number)

  Extra distance between slur and script.

`snap-radius` (number)

  The maximum distance between two objects that will cause them to snap to alignment along an axis.

`space-alist` (list)

  An alist that specifies distances from this grob to other breakable items, using the format:

  >     '((break-align-symbol . (spacing-style . space))
  >       (break-align-symbol . (spacing-style . space))
  >       ...)

  Standard choices for `break-align-symbol` are listed in break-alignment-interface. Additionally, three special break-align symbols available to `space-alist` are:

  > `first-note`

  >   used when the grob is just left of the first note on a line

  > `next-note`

  >   used when the grob is just left of any other note; if not set, the value of `first-note` gets used

  > `right-edge`

  >   used when the grob is the last item on the line (only compatible with the `extra-space` spacing style)

  Choices for `spacing-style` are:

  > `extra-space`

  >   Put this much space between the two grobs. The space is stretchable when paired with `first-note` or `next-note`; otherwise it is fixed.

  > `minimum-space`

  >   Put at least this much space between the left sides of both grobs, without allowing them to collide. The space is stretchable when paired with `first-note` or `next-note`; otherwise it is fixed. Not compatible with `right-edge`.

  > `fixed-space`

  >   Only compatible with `first-note` and `next-note`. Put this much fixed space between the grob and the note.

  > `minimum-fixed-space`

  >   Only compatible with `first-note` and `next-note`. Put at least this much fixed space between the left side of the grob and the left side of the note, without allowing them to collide.

  > `semi-fixed-space`

  >   Only compatible with `first-note` and `next-note`. Put this much space between the grob and the note, such that half of the space is fixed and half is stretchable.

  Rules for this spacing are much more complicated than this. See [Wanske] page 126–134, [Ross] page 143–147.

`space-to-barline` (boolean)

  If set, the distance between a note and the following non-musical column will be measured to the bar line instead of to the beginning of the non-musical column. If there is a clef change followed by a bar line, for example, this means that we will try to space the non-musical column as though the clef is not there.

`spacing-increment` (dimension, in staff space)

  The unit of length for note-spacing. Typically, the width of a note head. See also spacing-spanner-interface.

`spacing-pair` (pair)

  A pair of alignment symbols which set an object’s spacing relative to its left and right `BreakAlignment`s.

  For example, a `MultiMeasureRest` will ignore prefatory items at its bounds (i.e., clefs, key signatures and time signatures) using the following override:

  >     \override MultiMeasureRest.spacing-pair =
  >                  #'(staff-bar . staff-bar)

`stacking-dir` (direction)

  Stack objects in which direction?

`staff-affinity` (direction)

  The direction of the staff to use for spacing the current non-staff line. Choices are `UP`, `DOWN`, and `CENTER`. If `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. Setting `staff-affinity` for a staff causes it to be treated as a non-staff line. Setting `staff-affinity` to `#f` causes a non-staff line to be treated as a staff.

`staff-padding` (dimension, in staff space)

  Maintain this much space between reference points and the staff. Its effect is to align objects of differing sizes (like the dynamics p and f) on their baselines.

`staff-position` (number)

  Vertical position, measured in half staff spaces, counted from the middle line.

`staff-space` (dimension, in staff space)

  Amount of space between staff lines, expressed in global `staff-space`.

`staff-staff-spacing` (list)

  When applied to a staff-group’s `StaffGrouper` grob, this spacing alist controls the distance between consecutive staves within the staff-group. When applied to a staff’s `VerticalAxisGroup` grob, it controls the distance between the staff and the nearest staff below it in the same system, replacing any settings inherited from the `StaffGrouper` grob of the containing staff-group, if there is one. This property remains in effect even when non-staff lines appear between staves. The alist can contain the following keys:

  - `basic-distance` – the vertical distance, measured in staff-spaces, between the reference points of the two items when no collisions would result, and no stretching or compressing is in effect.
  - `minimum-distance` – the smallest allowable vertical distance, measured in staff-spaces, between the reference points of the two items, when compressing is in effect.
  - `padding` – the minimum required amount of unobstructed vertical whitespace between the bounding boxes (or skylines) of the two items, measured in staff-spaces.
  - `stretchability` – a unitless measure of the dimension’s relative propensity to stretch. If zero, the distance will not stretch (unless collisions would result).
`staffgroup-staff-spacing` (list)

  The spacing alist controlling the distance between the last staff of the current staff-group and the staff just below it in the same system, even if one or more non-staff lines exist between the two staves. If the `staff-staff-spacing` property of the staff’s `VerticalAxisGroup` grob is set, that is used instead. See `staff-staff-spacing` for a description of the alist structure.

`stem-attachment` (pair of numbers)

  An `(x . y)` pair where the stem attaches to the notehead.

`stem-begin-position` (number)

  User override for the begin position of a stem.

`stencil` (stencil)

  The symbol to print.

`stencils` (list)

`strict-note-spacing` (boolean)

  If set, unbroken columns with non-musical material (clefs, bar lines, etc.) are not spaced separately, but put before musical columns.

`stroke-style` (string)

  Set to `"grace"` to turn stroke through flag on.

`style` (symbol)

  This setting determines in what style a grob is typeset. Valid choices depend on the `stencil` callback reading this property.

`text` (markup)

  Text markup. See Formatting text.

`text-direction` (direction)

  This controls the ordering of the words. The default `RIGHT` is for roman text. Arabic or Hebrew should use `LEFT`.

`thick-thickness` (number)

  Thickness of the thick line in a bar line, expressed as a multiple of the default staff-line thickness (i.e. the visual output is not influenced by changes to `Staff.StaffSymbol.thickness`).

`thickness` (number)

  For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual „pen“ that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e. the visual output is influenced by changes to `Staff.StaffSymbol.thickness`).

`tie-configuration` (list)

  List of `(position . dir)` pairs, indicating the desired tie configuration, where position is the offset from the center of the staff in staff space and dir indicates the direction of the tie (`1`=>up, `-1`=>down, `0`=>center). A non-pair entry in the list causes the corresponding tie to be formatted automatically.

`to-barline` (boolean)

  If true, the spanner will stop at the bar line just before it would otherwise stop.

`toward-stem-shift` (number)

  Amount by which scripts are shifted toward the stem if their direction coincides with the stem direction. `0.0` means centered on the note head (the default position of most scripts); `1.0` means centered on the stem. Interpolated values are possible.

`toward-stem-shift-in-column` (number)

  Amount by which a script is shifted toward the stem if its direction coincides with the stem direction and it is associated with a `ScriptColumn` object. `0.0` means centered on the note head (the default position of most scripts); `1.0` means centered on the stem. Interpolated values are possible.

`transparent` (boolean)

  This makes the grob invisible.

`tuplet-slur` (boolean)

  Draw a slur instead of a bracket for tuplets.

`uniform-stretching` (boolean)

  If set, items stretch proportionally to their natural separation based on durations. This looks better in complex polyphonic patterns.

`voiced-position` (number)

  The staff-position of a voiced `Rest`, negative if the rest has `direction` `DOWN`.

`when` (moment)

  Global time step associated with this column.

`whiteout` (boolean-or-number)

  If a number or true, the grob is printed over a white background to white-out underlying material, if the grob is visible. A number indicates how far the white background extends beyond the bounding box of the grob as a multiple of the staff-line thickness. The `LyricHyphen` grob uses a special implementation of whiteout: A positive number indicates how far the white background extends beyond the bounding box in multiples of `line-thickness`. The shape of the background is determined by `whiteout-style`. Usually `#f` by default.

`whiteout-style` (symbol)

  Determines the shape of the `whiteout` background. Available are `'outline`, `'rounded-box`, and the default `'box`. There is one exception: Use `'special` for `LyricHyphen`.

  Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

`X-offset` (number)

  The horizontal amount that this object is moved relative to its X-parent.

  Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

`Y-offset` (number)

  The vertical amount that this object is moved relative to its Y-parent.

`zigzag-length` (dimension, in staff space)

  The length of the lines of a zigzag, relative to `zigzag-width`. A value of `1` gives 60-degree zigzags.

`zigzag-width` (dimension, in staff space)
