LilyPond Internals Reference: 3.2.92 semi-tie-interface

### 3.2.92 semi-tie-interface

A tie which is only on one side connected to a note head.

#### User settable properties:

> `control-points` (list)

>   List of offsets (number pairs) that form control points for the tie, slur, or bracket shape. For Béziers, this should list the control points of a third-order Bézier curve.

> `direction` (direction)

>   If `side-axis` is `0` (or `#X`), then this property determines whether the object is placed `#LEFT`, `#CENTER` or `#RIGHT` with respect to the other object. Otherwise, it determines whether the object is placed `#UP`, `#CENTER` or `#DOWN`. Numerical values may also be used: `#UP`=`1`, `#DOWN`=`-1`, `#LEFT`=`-1`, `#RIGHT`=`1`, `#CENTER`=`0`.

> `details` (list)

>   Alist of parameters for detailed grob behavior. More information on the allowed parameters for a grob can be found by looking at the top of the Internals Reference page for each interface having a `details` property.

> `head-direction` (direction)

>   Are the note heads left or right in a semitie?

> `thickness` (number)

>   Line thickness, generally measured in `line-thickness`.

#### Internal properties:

> `note-head` (graphical (layout) object)

>   A single note head.

This grob interface is used in the following graphical object(s): LaissezVibrerTie and RepeatTie.
