LilyPond Internals Reference: 3.1.28 ClusterSpanner

### 3.1.28 ClusterSpanner

ClusterSpanner objects are created by: Cluster_spanner_engraver.

Standard settings:

> `minimum-length` (dimension, in staff space):

>   `0.0`

>   Try to make a spanner at least this long, normally in the horizontal direction. This requires an appropriate callback for the `springs-and-rods` property. If added to a `Tie`, this sets the minimum distance between noteheads.

> `padding` (dimension, in staff space):

>   `0.25`

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

> `springs-and-rods` (boolean):

>   `ly:spanner::set-spacing-rods`

>   Dummy variable for triggering spacing routines.

> `stencil` (stencil):

>   `ly:cluster::print`

>   The symbol to print.

> `style` (symbol):

>   `'ramp`

>   This setting determines in what style a grob is typeset. Valid choices depend on the `stencil` callback reading this property.

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