3.1.9 Arpeggio

An arpeggio line (normally a vertical wiggle).

Arpeggio objects are created by: Arpeggio_engraver and Span_arpeggio_engraver.

Standard settings:

direction (direction):

-1

If side-axis is 0 (or X), then this property determines whether the object is placed LEFT, CENTER or RIGHT with respect to the other object. Otherwise, it determines whether the object is placed UP, CENTER or DOWN. Numerical values may also be used: UP=1, DOWN=-1, LEFT=-1, RIGHT=1, CENTER=0.

line-thickness (number):

1

For slurs and ties, this is the diameter of the virtual “pen” that draws the two arcs of the curve’s outline, which intersect at the endpoints. 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).

padding (dimension, in staff space):

0.5

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

positions (pair of numbers):

ly:arpeggio::calc-positions

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.

protrusion (number):

0.4

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

script-priority (number):

0

A key for determining the order of scripts in a stack, by being added to the position of the script in the user input, the sum being the overall priority. Smaller means closer to the head.

side-axis (number):

0

If the value is X (or equivalently 0), the object is placed horizontally next to the other object. If the value is Y or 1, it is placed vertically.

staff-position (number):

0.0

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

For ties, there is a distinction between exact and inexact values: an exact value serves as a rough vertical offset that gets further tuned to make the tie avoid staff lines. An inexact value is taken as the precise vertical offset without further adjustments.

stencil (stencil):

ly:arpeggio::print

The symbol to print.

thickness (number):

1

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).

X-extent (pair of numbers):

ly:arpeggio::width

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

X-offset (number):

ly:side-position-interface::x-aligned-side

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

Note that many objects have special positioning considerations, which cause any setting of X-offset to be ignored or modified, even though the object supports the self-alignment-interface.

Y-extent (pair of numbers):

#<unpure-pure-container #<procedure ly:grob::stencil-height (_)> #<procedure ly:arpeggio::pure-height (_ _ _)> >

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

Y-offset (number):

#<unpure-pure-container #<procedure ly:staff-symbol-referencer::callback (_)> >

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

Note that many objects have special positioning considerations, which cause any setting of Y-offset to be ignored or modified, even though the object supports the self-alignment-interface.

This object supports the following interface(s): arpeggio-interface, font-interface, grob-interface, item-interface, side-position-interface and staff-symbol-referencer-interface.

This object is of class Item (characterized by item-interface).
