LilyPond program-reference: 3.1.127 VoltaBracket

### 3.1.127 VoltaBracket

VoltaBracket objects are created by: Volta_engraver.

Standard settings:

> `stencil` (unknown):

>   `ly:volta-bracket-interface::print`

>   The symbol to print.

> `font-encoding` (symbol):

>   `'fetaNumber`

>   The font encoding is the broadest category for selecting a font. Currently, only lilypond’s system fonts (Emmentaler and Aybabtu) are using this property. Available values are `fetaMusic` (Emmentaler), `fetaBraces` (Aybabtu), `fetaNumber` (Emmentaler), and `fetaDynamic` (Emmentaler).

> `thickness` (number):

>   `1.6`

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

> `edge-height` (pair):

>   `'(2.0 . 2.0)`

>   A pair of numbers specifying the heights of the vertical edges: `(left-height . right-height)`.

> `font-size` (number):

>   `-4`

>   The font size, compared to the ‘normal’ size. `0` is style-sheet’s normal size, `-1` is smaller, `+1` is bigger. Each step of 1 is approximately 12% larger; 6 steps are exactly a factor 2 larger. Fractional values are allowed.

> `word-space` (dimension, in staff space):

>   `0.6`

>   Space to insert between words in texts.

> `direction` (direction):

>   `1`

>   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`.

This object supports the following interface(s): volta-bracket-interface, text-interface, spanner-interface, side-position-interface, line-interface, horizontal-bracket-interface, font-interface and grob-interface.
