### 3.1.8 `AmbitusNoteHead`

A note head in an `Ambitus`.

`AmbitusNoteHead` objects are created by: `Ambitus_engraver`.

Standard settings:

`duration-log` (integer):

`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): `ambitus-interface`, `font-interface`, `grob-interface`, `item-interface`, `ledgered-interface`, `note-head-interface` and `staff-symbol-referencer-interface`.
