3.1.95 NoteHead

A note head. See also TabNoteHead.

NoteHead objects are created by: Completion_heads_engraver, Drum_notes_engraver and Note_heads_engraver.

Standard settings:

bend-me (boolean):

'()

Decide whether this grob is bent.

duration-log (integer):

note-head::calc-duration-log

The 2-log of the note head duration, i.e., 0 = whole note, 1 = half note, etc.

extra-spacing-height (pair of numbers):

ly:note-head::include-ledger-line-height

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).

glyph-name (string):

note-head::calc-glyph-name

The glyph name within the font.

In the context of (span) bar lines, glyph-name represents a processed form of glyph, where decisions about line breaking, etc., are already taken.

parenthesis-friends (list):
'(accidental-grob dot)

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.

stem-attachment (pair of numbers):

ly:note-head::calc-stem-attachment

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

stencil (stencil):

ly:note-head::print

The symbol to print.

X-offset (number):

ly:note-head::stem-x-shift

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

Y-extent (pair of numbers):

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

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

This object supports the following interface(s): bend-interface, font-interface, gregorian-ligature-interface, grob-interface, item-interface, ledgered-interface, ligature-head-interface, mensural-ligature-interface, note-head-interface, rhythmic-grob-interface, rhythmic-head-interface, staff-symbol-referencer-interface and vaticana-ligature-interface.

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