### 3.2.38 footnote-spanner-interface

Make a footnote spanner.

#### User settable properties:

> `footnote-text` (markup)

>   A footnote for the grob.

#### Internal properties:

> `spanner-placement` (direction)

>   The place of an annotation on a spanner. `LEFT` is for the first spanner, and `RIGHT` is for the last. `CENTER` will place it on the broken spanner that falls closest to the center of the length of the entire spanner, although this behavior is unpredictable in situations with lots of rhythmic diversity. For predictable results, use `LEFT` and `RIGHT`.

This grob interface is used in the following graphical object(s): FootnoteSpanner.
