LilyPond Internals Reference: 3.1.46 GraceSpacing

### 3.1.46 GraceSpacing

GraceSpacing objects are created by: Grace_spacing_engraver.

Standard settings:

> `common-shortest-duration` (moment):

>   `grace-spacing::calc-shortest-duration`

>   The most common shortest note length. This is used in spacing. Enlarging this sets the score tighter.

> `shortest-duration-space` (dimension, in staff space):

>   `1.6`

>   Start with this much space for the shortest duration. This is expressed in `spacing-increment` as unit. See also spacing-spanner-interface.

> `spacing-increment` (number):

>   `0.8`

>   Add this much space for a doubled duration. Typically, the width of a note head. See also spacing-spanner-interface.

This object supports the following interface(s): grace-spacing-interface, grob-interface, spacing-options-interface and spanner-interface.
