3.1.87 MetronomeMark

A metronome mark. This is either a precise tempo indication like ‘quarter note = 80’, or an arbitrary piece of text (like ‘Allegro’), possibly followed by a precise indication in parentheses.

MetronomeMark objects are created by the following engraver(s): Metronome_mark_engraver.

Standard settings:

after-line-breaking (boolean):

ly:side-position-interface::move-to-extremal-staff

Dummy property, used to trigger callback for after-line-breaking.

break-align-symbols (list):

'(time-signature)

A list of break-align symbols that determines which breakable items to align this to. If the grob selected by the first symbol in the list is invisible due to break-visibility, we will align to the next grob (and so on). Choices are listed in break-alignment-interface.

break-visibility (vector):

#(#f #t #t)

A vector of 3 booleans, #(end-of-line unbroken begin-of-line). #t means visible, #f means killed.

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.

extra-spacing-width (pair of numbers):

'(+inf.0 . -inf.0)

In the horizontal spacing problem, we pad each item by this amount (by adding the ‘car’ on the left side of the item and adding the ‘cdr’ on the right side of the item). In order to make a grob take up no horizontal space at all, set this to (+inf.0 . -inf.0).

flag-style (symbol):

'default

The style of flags to be displayed within markups (via \note-by-number). Available are 'modern-straight-flag, 'old-straight-flag, 'flat-flag, 'mensural, 'stacked, and 'default.

non-break-align-symbols (list):

'(paper-column-interface)

A list of symbols that determine which NON-break-aligned interfaces to align this to.

outside-staff-horizontal-padding (number):

0.2

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.

outside-staff-priority (number):

1300

If set, the grob is positioned outside the staff in such a way as to avoid all collisions. In case of a potential collision, the grob with the smaller outside-staff-priority is closer to the staff.

padding (dimension, in staff space):

0.8

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

self-alignment-X (number):

-1

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. If not a number, align on the object’s reference point.

side-axis (number):

1

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.

stencil (stencil):

ly:text-interface::print

The symbol to print.

vertical-skylines (pair of skylines):

#<unpure-pure-container ly:grob::vertical-skylines-from-stencil >

Two skylines, one above and one below this grob.

X-offset (number):

self-alignment-interface::self-aligned-on-breakable

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 ly:grob::stencil-height >

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

Y-offset (number):

#<unpure-pure-container ly:side-position-interface::y-aligned-side ly:side-position-interface::pure-y-aligned-side >

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): break-alignable-interface, font-interface, grob-interface, item-interface, metronome-mark-interface, outside-staff-interface, self-alignment-interface, side-position-interface and text-interface.

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