LilyPond Internals Reference: 3.2.5 ambitus-interface

### 3.2.5 ambitus-interface

The line between note heads for a pitch range.

#### User settable properties:

> `gap` (dimension, in staff space)

>   Size of a gap in a variable symbol.

> `length-fraction` (number)

>   Multiplier for lengths. Used for determining ledger lines and stem lengths.

> `maximum-gap` (number)

>   Maximum value allowed for `gap` property.

> `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`).

#### Internal properties:

> `note-heads` (array of grobs)

>   An array of note head grobs.

This grob interface is used in the following graphical object(s): Ambitus, AmbitusLine and AmbitusNoteHead.
